PCD Flat-Bottom Drill Ø6 mm with 2×60° + 1×45° Chamfers – PCD-FBD-60×2-45×1-06-V1

Overview

This PCD flat-bottom drill is designed for precision drilling in non-ferrous and abrasive materials such as aluminum alloys, copper alloys, composites, and engineering plastics. The PCD cutting edges deliver excellent wear resistance and stable edge quality under high-speed machining conditions, helping maintain consistent hole size, burr control, and chamfer geometry throughout long production runs.

The compound chamfer configuration (2×60° + 1×45°) is engineered for parts requiring multiple edge treatments at the hole entrance or stepped hole features. By integrating these chamfers into the drilling tool itself, manufacturers can complete hole machining in one pass while reducing setup complexity and minimizing variation caused by separate drilling and chamfering tools.

Why Use a PCD Flat-Bottom Drill with Integrated Chamfers?

In automated CNC production, separate drilling and chamfering operations typically increase:

• cycle time

• tool changes

• spindle movements and positioning steps

• risk of chamfer misalignment

• burr rework or manual finishing

By combining flat-bottom drilling with multi-angle chamfer generation, this tool delivers a streamlined machining sequence and consistent feature relationships. The flat-bottom geometry supports controlled seating surfaces and accurate depth control, while the integrated chamfers produce repeatable edge geometry without secondary operations.

Compared with carbide flat-bottom drills, PCD flat-bottom drills typically provide more stable wear behavior and longer service life in non-ferrous and abrasive materials, especially when burr-free edge quality is required over extended batches.

Applications

This PCD flat-bottom drill is commonly used for:

• Flat-bottom hole drilling in aluminum alloys, copper alloys, composites, and plastics

• Automotive and aerospace components requiring controlled hole depth and chamfer geometry

• Mold and die parts with flat seating surfaces or stepped-hole requirements

• High-volume production lines where cycle time and tool changes must be minimized

• Precision components where secondary chamfering operations are undesirable

• Parts requiring repeatable chamfer angles for assembly, sealing, or fastener seating functions

Key Features

• True flat-bottom drilling geometry for controlled hole bottom surfaces

• Integrated compound chamfers – 2×60° + 1×45° generated in the same operation

• PCD cutting edges for long tool life and stable performance in non-ferrous materials

• One-pass multi-function design combining drilling and chamfering

• High concentricity control for consistent hole positioning and chamfer alignment

• Optimized flute geometry for chip evacuation and burr reduction

• Optional through-coolant for thermal stability and chip control

Benefits in Production

Using this tool provides measurable production advantages:

• Reduced machining time by eliminating secondary chamfering steps

• Improved hole bottom flatness and consistent depth control

• Repeatable chamfer quality with stable angle and width control

• Lower tool change frequency and improved machine uptime

• Reduced burr formation and reduced manual finishing requirements

• Longer tool life compared with carbide or HSS drilling solutions in non-ferrous applications

• Higher productivity and lower cost per part in mass production

For high-volume manufacturing, the main benefit is process repeatability: hole geometry and chamfer features remain consistent across long production cycles with minimal tool-related variation.

Machining Notes for Engineers

To maximize performance and ensure consistent results:

• Maintain correct preconditions for chip evacuation, especially in deep holes

• Select appropriate coolant strategy (external coolant, MQL, or through-coolant) based on material and hole depth

• Control runout and tool holding stability to maintain chamfer symmetry

• Ensure program entry approach supports stable chamfer formation and avoids tool bounce

• Use material-appropriate cutting parameters to prevent built-up edge in ductile aluminum alloys

Aoshiji® can adjust edge preparation and flute geometry according to workpiece material condition (die-cast vs wrought aluminum, silicon content, copper alloy type, composite reinforcement type).
