ASTMELINE PUUR COBALT 6-35mm

The new aluminum chromium nitride coating (AlCrN) extends the bit's service life by 10x compared to standard MILWAUKEE® step drill bits. Suitable for steel and stainless steel. The RAPID STRIKE TIP facilitates starting screws, prevents bit slippage, and reduces heat generation during screwdriving. The specially designed tip and step geometry reduce the risk of bit jamming when using cordless tools and prevent material twisting. Optimized two-flute sharp edge geometry enables 2x faster and smoother drilling. Three even clamps prevent the step bit from slipping in the chuck and ensure optimal torque transfer. Laser-etched full markings remain visible for a long time. This product description is an automated translation of the original Finnish description.
