Product details

Drilling range 4.0 - 20.0 mm. Next generation - With this robust tool, sheets can be centered, pre-drilled, drilled, and deburred in a single operation. The deeply ground and spiral-shaped chip groove ensures absolute smooth operation and high cutting performance. In particular, non-breaking chips are transported away cleanly, similar to a spiral drill. This reduces the formation of built-up edges and cold welds on the cutting edges. The cone shape facilitates retraction when drilling through sheets. HSS Co 5: High-performance high-speed steel with a 5% cobalt content. High toughness and heat resistance, suitable for drilling in difficult-to-machine materials with a strength of up to 1100 N/mm².
