BOHRER 430HSS conical drill bit, 4-31 mm, Tenifer-treated.

HSS conical drill bit.
Drill hole diameter: 4 - 31 mm
Shank diameter: 9 mm

Tenifer-treated for surface hardening through reduced cold welding. Burr-free drilling and reaming of metal sheets, pipes, steel profiles, Cr-Ni steel, non-ferrous metal, acrylic glass and plastic up to a wall thickness of 5 mm.
The hole diameters are signed by laser in both grooves. The scale is legible when the tool is rotating. The three-sided tappet shank prevents "slipping" in the drill chuck.
