The Spiral Flute Tube and Sheet drills

Professional Tube and Sheet Drill

Spiral Flute Tube and Sheet drills, CBN ground, HSS
The Spiral Flute Tube and Sheet drills with a helical groove, which reduces the frictional resistance of the tool during the drilling. This contributes to a quieter performance and reduces the heating of the tool. The chips created during the drilling are continuously transported off and the sharpness of the blade maintains longer. The tip has a split point, which allows an easy drilling. 3-surface grip on the shank does not allow the tool to spin. Individual drilling diameters are clearly marked in the flutes. Ideal tools for alloyed and unalloyed sheets up to 4.0 mm, non-ferrous metals and plastics.
