Component Breakdown

Cutting Head
- Central Inserts: Primary cutting edges (KC7325 carbide grade).
- Finishing Inserts: Achieve Ra 0.8-3.2μm surface finish.
BTA Tube
- Matches hole diameter; delivers 70-150bar coolant for chip removal.
Guidance System
- Tungsten support pads (e.g., BTA-SP-50) prevent deflection and extend tool life.
