Step drill HSS-AlTiN 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
Made of HSS for a long service life. Laser markings for diameters.
AlTiN coating for maximum service life, laser markings for hole diameters, 3-face shank for high torque transfer
The step drill is made of HSS (High-Speed Steel) and coated with AlTiN (aluminium titanium nitride). This ensures maximum service life and makes the use of coolant unnecessary. 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.
