Custom Carbide-Tipped Counterbore Tools
Custom carbide-tipped counterbore tools are drawing-based cutting tools for machining flat-bottom recesses, stepped bores, angled seats, radiused transitions and combined form features in metal components.
The carbide cutting edges are brazed onto a steel tool body, so these tools are also described as custom brazed carbide counterbores. The carbide provides wear resistance and cutting-edge performance, while the steel body provides structural toughness, design flexibility and economical construction for larger or more complex tools.
Aoshiji® Custom Tool supplies straight, step, angled, radius-profile, combination and large-diameter counterbore cutters for applications where standard counterbore tools cannot meet the required geometry, tolerance, surface finish, burr condition, tool life or cost-per-part target.
These counterbores are commonly used in aerospace, automotive, and heavy machinery applications where non-standard dimensions, high wear resistance, stable cutting performance or complex recessed features are required.
Typical applications include:
- Flat-bottom counterbores
- Stepped recesses
- Formed blind holes
- Angled or tapered seats
- Radius transitions
- Combined counterbore and chamfer features
- Bearing cage and bearing retainer machining
- Large-diameter counterboring
- Drawing-specific form machining
- Roughing and finishing counterbore operations

01 What Is a Custom Counterbore Tool?
A counterbore tool produces a cylindrical recess around an existing or simultaneously machined hole. A conventional counterbore normally generates a larger-diameter, flat-bottom recess that is concentric with the smaller hole.
Custom counterbore tools extend this basic function by combining additional features such as:
- Multiple diameters
- Controlled counterbore depth
- Angled seats
- Tapered surfaces
- Internal radii
- Chamfers
- Formed bottom profiles
- Blended transitions
- Drawing-specific contours
Depending on the feature geometry and the terminology used by the customer, these tools may also be called:
- Counterbore cutters
- Counterbore cutting tools
- Form counterbores
- Profile counterbores
- Step counterbores
- Combination counterbores
- Piloted counterbores
- Carbide-tipped counterbores
- Brazed carbide counterbores
When the recess includes a radius, taper or combined profile rather than a conventional flat bottom, the terms form counterbore, profile counterbore or combination counterbore provide a more precise engineering description.For a broader explanation of carbide-tipped and brazed carbide tool construction, see our main product guide: Custom Carbide-Tipped Cutting Tools.
02 Carbide-Tipped vs Brazed Carbide Counterbores
In custom counterbore tooling, carbide-tipped counterbore and brazed carbide counterbore generally describe the same basic construction.
Carbide-Tipped Counterbore
The term carbide-tipped describes the tool structure. Carbide cutting edges, carbide tips or carbide bars are supported by a steel tool body.
Brazed Carbide Counterbore
The term brazed carbide describes the joining method. During controlled brazing, a brazing filler alloy melts to form a permanent bond between the carbide cutting sections and the steel body.The brazed joint is engineered to provide stable support while maintaining the required cutting geometry and dimensional accuracy. Compared with high-speed steel (HSS), carbide cutting edges retain hardness and cutting performance better at elevated machining temperatures.
For this product page:
- Carbide-tipped counterbores use brazed carbide cutting edges
- Brazed carbide counterbores have a steel supporting body
- The cutting profile is finish-ground after brazing
- The tool is designed according to the customer’s drawing and machining conditions
The two terms should be used together naturally without treating them as different tool categories.
03 Counterbore vs Countersink vs Spotface
| Feature | Geometry | Typical Purpose |
|---|---|---|
| Counterbore | Cylindrical recess with a flat or formed bottom | Recessing bolt or fastener heads, seats or drawing-specific features |
| Countersink | Conical recess | Seating flat-head screws or producing a chamfered entry |
| Spotface | Shallow flat-bottom machined surface | Producing a clean, perpendicular seating surface |
| Form counterbore | Recess with steps, angles, radii or combined profiles | One-pass production of a drawing-specific recess |
A counterbore should not automatically be described as a countersink. A countersink creates a conical surface, while a conventional counterbore creates a cylindrical recess.
A spotface is normally shallower than a counterbore and is used primarily to clean or level a seating surface.
Custom combination tools can machine two or more of these features in one operation when the tool strength, chip evacuation and dimensional relationships permit.
04 Types of Custom Counterbore Tools
Straight Flat-Bottom Counterbore
A straight counterbore produces a cylindrical recess with a controlled diameter and flat bottom.
Typical applications include:
- Bolt-head recesses
- Bearing component seats
- Flat-bottom blind recesses
- Controlled-depth counterbores
- Repeated-hole production
The cutting geometry can be designed to control bottom flatness, wall finish, corner condition and burr formation.
Angled or Tapered Form Counterbore
An angled counterbore produces a drawing-defined seat or tapered surface.
Important design variables include:
- Included angle
- Axial position
- Cutting-edge overlap
- Corner transition
- Profile tolerance
- Cutting-force direction
These tools are useful when angle consistency and contact geometry are more important than a conventional flat-bottom recess.
Radius-Profile Counterbore
A radius-profile counterbore produces a curved transition, formed bottom or blended recess.
Possible forms include:
- Full radius
- Partial radius
- Concave profile
- Convex transition
- Radius-to-angle combination
- Radius-to-step combination
The complete profile can be generated in one pass to avoid mismatch, witness marks or blend lines created by multiple tools.
Ball-Radius and Chamfer Combination Counterbore
A combination counterbore can integrate a ball-radius form with a chamfer or additional diameter.
This design may be selected when:
- Multiple tools would create alignment variation
- The feature must be completed in one setup
- Tool-change reduction is required
- A continuous drawing-defined profile must be maintained
Step Counterbore
A step counterbore produces two or more related diameters in one operation.
Possible features include:
- Pilot diameter
- Main counterbore diameter
- Secondary step
- Chamfer
- Radius transition
- Controlled shoulder depth
A step counterbore can reduce tool changes and maintain the dimensional relationship between related features.
Piloted Counterbore
A piloted counterbore uses an existing hole to help locate or stabilize the cutting tool.
Pilot options may include:
- Integral pilot
- Replaceable pilot
- Fixed pilot
- Drawing-specific guide diameter
- Pilotless construction when the machine setup provides sufficient guidance
The pilot diameter, pilot length and clearance must be matched to the pre-hole and cutting process.
05 When a Custom Counterbore Is Recommended
A custom counterbore tool should be considered when:
- The counterbore diameter is non-standard
- The feature includes multiple diameters
- A special depth relationship is required
- The recess includes a taper or angle
- The bottom includes a radius or formed profile
- A chamfer must be machined in the same operation
- The counterbore is unusually large or deep
- Standard pilots do not match the pre-hole
- Standard counterbore cutters produce excessive burrs
- Surface finish is unstable
- Chatter marks appear on the bore wall
- Cutting edges chip during interrupted cutting
- Tool life is too short
- Several standard tools are currently required
- One-pass form machining is preferred
- Solid carbide construction would be unnecessarily expensive
- Standard indexable inserts cannot reproduce the profile
A custom tool should be designed around the complete machining process rather than only the counterbore diameter and depth.
06 Counterbore Dimensions and Drawing Requirements
The following dimensions should be defined on the component or tool drawing.
Basic Geometry
- Counterbore diameter
- Pilot-hole diameter
- Counterbore depth
- Overall cutting length
- Tool overall length
- Shank diameter
- Pilot diameter
- Pilot length
Form Geometry
- Step diameters
- Step lengths
- Included angles
- Taper angles
- Corner radii
- Bottom radii
- Chamfer angle
- Chamfer width
- Profile coordinates
- Relief or clearance requirements
Quality Requirements
- Diameter tolerance
- Depth tolerance
- Profile tolerance
- Angle tolerance
- Concentricity
- Position tolerance
- Radial runout
- Axial runout
- Bottom flatness
- Surface-finish requirement
- Burr requirement
The drawing should clearly identify whether the tolerance applies to the tool, the machined component or both.
07 Cutting Geometry and Edge Preparation
Counterbore performance depends on the relationship between the cutting geometry, carbide grade, workpiece material and machine setup.Flute design and coating options can also be customized according to the workpiece material, cutting conditions, chip-evacuation requirements and target tool life.
Important design variables include:
- Number of cutting edges
- Tooth spacing
- Peripheral rake angle
- Axial rake angle
- Primary relief
- Secondary relief
- Side clearance
- Cutting-edge overlap
- Chip-gullet volume
- Carbide tip dimensions
- Carbide support behind the edge
- Corner radius
- Cutting direction
- Regrinding allowance
Edge Preparation Options
The cutting edge may be supplied with:
- Sharp edge
- Light hone
- Micro-radius
- Protective chamfer
- Combined chamfer and hone
Sharper cutting edges may be selected for copper alloys and burr-sensitive applications.
Stronger edge preparation may be required for ductile iron, interrupted cutting and applications with unstable engagement.
There is no universal edge preparation suitable for every counterboring application.
08 Pilot, Shank and Machine Interface Options
The tool interface must be matched to the machine, holder, cutting load and required overhang.
Possible configurations include:
- Straight shank
- Weldon-style flat
- Taper shank
- Morse taper
- BT interface adaptation
- HSK interface
- Cylindrical arbor
- Bore-mounted cutter
- Drawing-specific connection
- Integral pilot
- Replaceable pilot
- Pilotless form tool
For long or large-diameter tools, the design should consider:
- Tool-body core diameter
- Bending stiffness
- Connection rigidity
- Unsupported length
- Cutting-force direction
- Balance
- Machine spindle capacity
- Holder runout
A large cutting head on a small or excessively long shank may create deflection, chatter and uneven edge loading.
09 Workpiece Materials
Aoshiji counterbore designs are developed according to the actual material and machining conditions.
Brass, Bronze and Copper Alloys
Copper-alloy components may require:
- Sharp cutting geometry
- Smooth rake surfaces
- Controlled edge hone
- Burr-control-focused cutting action
- Reduced material adhesion
- Stable chip evacuation
- Protection against smearing or tearing
The required geometry depends on the exact copper alloy, hardness and workpiece condition.
For bearing cages and bearing retainers, common quality concerns include:
- Hard burrs at the recess edge
- Smearing on the bore wall
- Material adhesion
- Surface tearing
- Chatter marks
- Inconsistent surface finish
QT400 and QT500 Ductile Iron
QT400 and QT500 are ductile iron grades commonly used in Chinese engineering drawings. International buyers may also describe this material category as ductile cast iron or nodular cast iron.
Counterbore designs for ductile iron may require:
- Strong carbide-edge support
- Controlled micro-hone
- Resistance to edge chipping
- Rigid steel body
- Stable tooth engagement
- Sufficient chip-gullet volume
- Controlled radial and axial runout
Interrupted surfaces, casting variation and machine vibration must be considered during tool design.
Additional Materials
Other cast irons, carbon steels, alloy steels and non-ferrous materials can be evaluated from the drawing, hardness, cutting conditions and production target.
Carbide grade and cutting geometry should not be selected from the material name alone.
10 Burr Control and Surface Finish
Counterbore quality is influenced by both the cutting edge and the complete machining system.
Typical quality problems include:
- Hard burrs
- Rolled or smeared edges
- Bore-wall chatter marks
- Vibration patterns
- Tearing
- Poor bottom finish
- Profile mismatch
- Edge chipping
- Inconsistent counterbore depth
Burr-Control Design
For burr-sensitive applications, the tool may require:
- Sharper cutting geometry
- Controlled exit engagement
- Reduced edge adhesion
- Appropriate cutting direction
- Balanced tooth loading
- Stable feed
- Minimal runout
Surface-Finish Design
For improved surface finish, the design may include:
- Finishing edges
- Controlled edge overlap
- Low-runout grinding
- Profile-ground carbide
- Stable body geometry
- Defined regrinding allowance
- Separate roughing and finishing tools
Typical targets such as Ra 1.6 µm or Ra 3.2 µm must be reviewed together with material, allowance, machine condition, coolant and feed rate.
11 Rigidity, Runout and Cutting Stability
A counterbore can have the correct profile and still perform poorly if the complete system lacks rigidity.
Cutting stability depends on:
- Tool-body stiffness
- Shank diameter
- Tool overhang
- Pilot support
- Holder accuracy
- Spindle condition
- Workpiece clamping
- Cutting allowance
- Number of cutting edges
- Tooth-to-tooth runout
- Carbide brazing accuracy
- Dynamic balance
Excessive runout can cause one cutting edge to remove most of the material.
Possible results include:
- Uneven wear
- Chipping on the overloaded edge
- Oversized or tapered recesses
- Chatter
- Poor surface finish
- Short tool life
For large rotary counterbores, radial runout, axial runout and balance should be controlled as part of the manufacturing and inspection process.
12 Chip Evacuation and Coolant Strategy
Chip evacuation must be considered during the initial tool design.
Important variables include:
- Number of flutes
- Gullet depth
- Gullet width
- Cutting depth
- Blind-hole geometry
- Material chip form
- Tool orientation
- Coolant delivery
- Machine spindle direction
- Available chip space
Blind-Hole Counterboring
Blind recesses can cause chip accumulation between the tool and the finished surface, increasing the risk of recutting, surface damage and unstable chip evacuation.
The design may require:
- Larger chip gullets
- Open flute geometry
- Reduced tooth count
- External coolant directed toward the cutting zone
- Internal coolant where technically practical
- Controlled pecking or chip-clearing cycles
Dry and Emulsion Cutting
Some copper-alloy applications may use dry cutting or emulsion.
Ductile-iron applications may use dry cutting, air blast or emulsion depending on the machine and customer process.
The coolant strategy should be specified before the final edge geometry and chip-control design are approved.
13 Large-Diameter and Form Counterboring
Large-diameter counterbores can consume a substantial amount of carbide when manufactured as solid carbide tools.
Carbide-tipped construction uses carbide only in the cutting area while retaining a steel supporting body.
For large-diameter or complex-profile counterbores, this brazed construction can provide better cost efficiency than an equivalent solid-carbide design because carbide is concentrated at the cutting edges rather than throughout the complete tool body.
This construction can be practical for:
- Large cutting diameters
- Deep formed recesses
- Long tool bodies
- Heavy counterbore heads
- Multiple cutting features
- Drawing-specific profiles
- Low-to-medium production quantities
- Tools requiring future regrinding or retipping
Large-diameter design must still account for:
- Body strength
- Centrifugal loading
- Brazed-joint support
- Cutting-force balance
- Chip-gullet strength
- Machine power
- Maximum spindle speed
- Dynamic balance
- Safe operating parameters
The tool should not be operated at a rotational speed selected only from a standard small-diameter counterbore chart.
14 Roughing and Finishing Tool Strategy
A single counterbore can perform the complete operation when cutting allowance, rigidity and surface-finish requirements permit.
For demanding profiles, separate roughing and finishing tools may provide better process stability.
Roughing Counterbore
The roughing tool removes most of the material while leaving a controlled finishing allowance.
Possible roughing features include:
- Stronger cutting edges
- Larger chip gullets
- Reduced finished diameter
- Increased chip clearance
- Edge preparation for interrupted cutting
Finishing Counterbore
The finishing tool produces the final:
- Diameter
- Angle
- Radius
- Profile
- Depth relationship
- Surface finish
A roughing and finishing strategy may be recommended when:
- The counterbore diameter is large
- Cutting depth is substantial
- Interrupted cutting is present
- Surface finish is critical
- Profile tolerance is tight
- Chatter has occurred with a single-tool process
- Tool life is unstable
The roughing allowance must be specified per side and should remain consistent across the complete formed profile.
15 Wind-Turbine Bearing Cage Application Case
Brazed Carbide Form Counterbore for QT400/QT500 Bearing Cage Machining
A wind-turbine bearing-cage application required a large formed blind hole in QT400/QT500 ductile iron.
Component Requirement
| Item | Requirement |
|---|---|
| Finished diameter | Ø156.2 mm |
| Form angle | 6.75° |
| Machining depth | 159 mm |
| Diameter tolerance | 0 / +0.03 mm |
| Surface finish | Ra ≤ 3.2 µm |
| Cutting condition | Interrupted cutting with vibration risk |
| Machine | Horizontal boring machine |
| Coolant | External emulsion |
Tooling Strategy
The application used separate roughing and finishing counterbores.
The roughing tool was designed approximately 0.5 mm below the finishing diameter, leaving about 0.25 mm finishing allowance per side.
Both tools used the same drawing-defined form angle.
Engineering features included:
- Brazed carbide cutting edges
- Heat-treated alloy-steel body
- Two-flute form geometry
- Reinforced core
- Chip-control grooves
- Increased body rigidity
- Controlled edge preparation
- MT5 interface adapted to BT50
- Dynamic balancing
- Drawing-specific profile grinding
Machining Parameters
| Parameter | Value |
|---|---|
| Spindle speed | 200 r/min |
| Feed rate | 30 mm/min |
Production Result
The previous roughing tool produced approximately 8 components.
The optimized brazed carbide roughing counterbore produced approximately 28 components under the documented customer conditions.
The application also achieved:
- Stable finished diameter
- Consistent form angle
- Reduced chatter marks
- Improved chip evacuation
- Fewer edge-chipping failures
- More stable production cycles
- Lower tooling cost per completed component
These results apply to the documented machine, component, material and cutting conditions. Other applications require individual engineering review.
16 Manufacturing and Quality Control

Possible reconditioning options include:
- Face regrinding
- Relief regrinding
- Profile regrinding
- Diameter correction
- Edge re-preparation
- Retipping
- Steel-body rebuilding
Regrinding feasibility depends on:
- Remaining carbide thickness
- Original regrinding allowance
- Fixed finished diameter
- Profile tolerance
- Pilot relationship
- Tool-body condition
- Brazed-joint condition
- Previous regrinding history
A regrind drawing or inspection record is recommended for tools with multiple profiles or tight dimensional relationships.
Repeat production can be controlled by:
- Tool drawing number
- Drawing revision
- Customer part number
- Approved tool photograph
- Material and carbide grade record
- Inspection report
- Regrinding history

20 Frequently Asked Questions
What is a counterbore tool?
A counterbore tool machines a larger-diameter recess around a smaller hole. A conventional counterbore normally produces a cylindrical recess with a flat bottom, while a custom form counterbore may also generate steps, angles, radii or combined profiles.
What is a counterbore used for?
Counterbores are used to create recessed seats, flat-bottom cavities, bolt-head recesses, bearing-component features and drawing-specific formed recesses.
What is the difference between a counterbore and a countersink?
A counterbore normally creates a cylindrical recess with a flat or formed bottom. A countersink creates a conical recess, usually for a flat-head fastener or chamfered entry.
What information is required for a counterbore quotation?
Provide the component or tool drawing, material, hardness, dimensions, tolerances, surface finish, machine interface, coolant method, current cutting parameters, production quantity and current tooling problem.
What is the difference between a counterbore and a spotface?
A spotface is normally a shallow machined seating surface. A counterbore is generally deeper and creates a defined recess around a hole.
Is carbide-tipped the same as brazed carbide?
In Aoshiji custom counterbore tooling, the terms normally describe the same construction. Carbide-tipped describes the carbide cutting edge, while brazed carbide describes how the carbide is joined to the steel body.
When should a custom counterbore be used?
A custom counterbore should be considered when the diameter, depth, pilot, step, angle, radius or combined profile cannot be produced efficiently with a standard counterbore tool.
Do you support cutting-tool distributors?
Yes. Aoshiji supports distributors and industrial tooling suppliers with drawing review, technical evaluation, custom-tool production and revision-controlled repeat orders.
Can a counterbore machine multiple features in one pass?
Yes. A custom combination counterbore can integrate diameters, steps, angles, radii and chamfers when the geometry, tool strength and chip evacuation permit one-pass machining.
Can you manufacture a large-diameter counterbore?
Yes. Carbide-tipped construction is often practical for large-diameter counterbores because carbide is concentrated at the cutting edges while the main supporting body is made from steel.
Can a counterbore have an integral pilot?
Yes. The pilot may be integral, replaceable or omitted depending on the pre-hole, machine setup, toolholder and required guidance.
Can one tool achieve the final counterbore surface finish?
A single tool may achieve the final result in stable applications. Large, deep or vibration-sensitive profiles may require separate roughing and finishing counterbores.
Many brazed carbide counterbores can be reground when sufficient carbide and regrinding allowance remain. The profile, diameter, relief, pilot relationship and runout must be checked after regrinding.
Retipping may be possible when the steel body remains dimensionally stable and undamaged. The economic feasibility depends on tool size, profile complexity and rebuilding cost.
Typical Aoshiji applications include brass, bronze, copper alloys and QT400/QT500 ductile iron. Other cast irons, steels and non-ferrous materials can be evaluated from the drawing and machining conditions.
A properly designed cutting edge, rake geometry, edge preparation, cutting direction and stable machine setup can reduce burr formation. The result depends on the exact material, allowance and process conditions.
