Product description
Step drill HSS-TiN can make smooth bores of various diameters with one drill
CNC ground spiral groove provides optimized chip evacuation and reduced vibration for even bores
Excellent cutting smoothness thanks to axial and radial back grinding
TiN coating for long life. Laser markings for diameters. 3-face shank for high torque transfer
The step drill is made of HSS (High-Speed Steel) and coated with TiN (titanium nitride). This ensures an exceptionally long service life when using coolant. The hole diameters in both spiral grooves are clearly visible and permanently marked with the aid of a laser. In addition, the 3-face shank prevents slippage in the drill chuck and ensures a high torque transfer.
