High-Performance Drilling Machining Logic
The 870-2100-21-PM 4334 is an exchangeable drill tip engineered for high-process security in steel Holemaking. Its Machining Logic centers on a robust PM geometry that balances edge strength with efficient Chip Evacuation, specifically for P-group materials. The Insert Seat interface (Size 21) is designed to withstand extreme torque, providing the necessary Clamping Force to maintain Stability during high-feed operations. When used with a CoroDrill® 870 body, it delivers H10 tolerance precision in various Milling centers and CNC machines.
