Product Information
CBN ground flute
Because CBN ground flutes have better and sharper cutting edges - without burrs - unlike the conventional milled flutes.
This guarantees a superior cutting edge and longer tool life.
Radially adjusted relief produced by CBN grinding
Because radially adjusted relief produced by CBN grinding relates directly to its diameter, the cutting edge is always
the highest point of the diameter.
Flute
The straight or spiral flute offers absolute running smoothness and high cutting performance.
In the spiral flute non-breaking chips in particular are transported away cleanly as with a spiral drill.
Cone at the end
The cone at the end of these tube and sheet drills makes it easier to withdraw the tool from the material.
CBN ground bit with split point DIN 1412 C
The CBN ground bit ensures centering and spot-drilling even in thin-walled material.
