Step Drill Bit Milwaukee AlCrN 4-20 mm

The new aluminum chromium nitride (AlCrN) coating ensures 10x longer lifespan than the standard MILWAUKEE® step drill bit.
For steel and stainless steel.
RAPID STRIKE TIP™: The quick strike tip improves centering: less slipping and faster drilling without pre-punching or drilling.
The special shape of the tip and steps prevents jamming: less risk of the drill bit getting stuck when using a fast cordless drill; also prevents deformation of the material being drilled.
The optimized shape of the two ground cutting edges ensures 2x faster and smoother cutting.
3 flat secure attachment prevents the step drill bit from slipping in the chuck and ensures maximum torque transfer.
Laser-engraved size marking ensures the best long-term visibility.
