PCD Keyseat Cutter Head – High Precision Slotting & Keyseat Cutter
Overview
The PCD Keyseat Cutter Head from Aoshiji® Custom Tool is a precision-engineered slotting and keyseat milling solution designed for CNC machining of aluminum alloys, non-ferrous metals, composites, and plastics. Built with polycrystalline diamond (PCD) cutting edges, it provides outstanding wear resistance, long service life, and superior surface finish—making it ideal for high-volume slotting and keyseat operations.
As a head-only design (without shank), it offers maximum flexibility by mounting onto arbor-based or modular toolholder systems, ensuring compatibility with diverse CNC machining setups.
Applications
Precision slotting and keyseat machining in non-ferrous metals and composites
Automotive & aerospace components requiring high-accuracy grooves and slots
Mold & die manufacturing with critical slot features
CNC machining centers utilizing modular toolholder systems
Key Features
PCD cutting edges – Exceptional wear resistance and stable cutting action
Head-only design – Compatible with multiple arbors and modular holders
High accuracy – Maintains precise slot width and smooth wall finish
Optimized chip evacuation – Gullet design prevents clogging and improves reliability
Customizable geometry – Diameter, slot width, tooth count, and coolant options tailored per drawing
Benefits
Flexible use across various CNC toolholder and arbor systems
Longer tool life compared with carbide slotting cutters
Consistent accuracy for slots, keyseats, and grooves
Reduced cycle time by achieving precision in one pass
Lower cost per part in high-volume production
