PCD Countersink 90° Ø10 mm – PCD-CSK-90-10-V1 | Aoshiji® Custom Tool
Aoshiji® Custom Tool offers the PCD countersink 90° Ø10 mm (Model PCD-CSK-90-10-V1) for precision chamfering and countersinking on pre-drilled holes, delivering burr-free edges and stable countersink geometry in high-volume CNC machining applications.
Overview
This PCD countersink is specifically designed for precision chamfering of pre-drilled holes in aluminum, composites, and non-ferrous materials, where burr-free edges, dimensional consistency, and long tool life are critical.
The PCD Countersink 90° Ø10 mm (Model PCD-CSK-90-10-V1) features polycrystalline diamond (PCD) cutting edges that provide exceptional wear resistance, minimal edge degradation, and superior surface finish compared with carbide or HSS countersinks.
By maintaining stable tool engagement and accurate concentricity, this PCD countersink is well suited for high-volume production environments where consistent countersink quality and reduced tool changes are required.
Why Choose a PCD Countersink for Precision Chamfering?
Compared with carbide countersinks, PCD countersinks offer significantly longer tool life and more stable cutting performance when machining abrasive and non-ferrous materials such as aluminum alloys, CFRP, and engineering plastics.
This makes PCD countersinks particularly effective in applications requiring consistent countersink geometry, clean edges, and reduced downtime in serial production.
Applications
Countersinking and chamfering on pre-drilled holes in aluminum alloys, copper, brass, composites, and engineering plastics
Automotive and aerospace components requiring high-precision countersinks
Mold and die manufacturing and other precision engineering applications
Flathead screw seats and deburring operations at 90°
Custom countersinking requirements (available angles: 60°, 82°, 100°)
Key Features
One-pass precision – Produces accurate 90° countersinks in a single operation
PCD cutting edges – Outstanding wear resistance and extended tool life
High concentricity – Ensures consistent countersink size, position, and depth
Optimized flute design – Smooth chip evacuation and reduced burr formation
Guided tip design (optional) – Improves tool stability and concentricity during countersinking on pre-drilled holes
Customizable geometry – Diameter, angle, flute configuration, and shank type tailored to application requirements
Benefits
Shorter cycle time with fewer tool changes
Superior countersink quality with burr-free edges and smooth surface finish
Longer service life compared with carbide and HSS countersinks
Lower cost per part in high-volume CNC machining environments
