Size No. 1. Drilling range 4.0 - 20.0 mm.NEXT GENERATION - With this robust tool, sheets can be centered, drilled, drilled and deburred in one operation.The deep-ground and spiral-shaped clamping groove offers absolute smoothness and high cutting performance. In particular, chips that do not break are cleanly transported away as with a twist drill. This reduces the formation of surface-mounted cutting edges and cold welding on the cutting edges. The cone makes it easier to pull back on pierced sheets. HSS: High-performance high-speed working steel for drilling in well-machined materials with a strength of up to 900 N/mm².This text is machine translated.
