Specification

Solid carbide high-performance drill with internal cooling channels specially designed for machining aluminium. Six guide chamfers guarantee excellent alignment accuracy and stabilisation of the drill bit even at very high cutting speeds and feed rates. The special coating prevents built-up edges due to extremely smooth surface.
