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.
Tin: The titanium nitrite coating is a universal standard layer.
It offers a 300-400% longer service life compared to uncoated tools.
Cooling is recommended.
