Deep-hole Drills Increase Metal Removal

May 30, 2011

In deep-hole drilling applications up to 30xD, new solid-carbide WIDIA-Rubig deep-hole drills remove between three and four times the metal compared to gun drills, in addition to delivering excellent hole quality and cycle times, reports the manufacturer.

Length ratios for the new deep-hole drills are available in 15xD, 20xD, 25xD, and 30xD. Available diameters are from 3.0 to 13.0 mm.

These drills require no special drivers or guide bushings.

The drills have a 132-degree, cone-point geometry and a four-margin design. They are PVD-coated and polished to increase wear resistance and reduce friction on the margins and cutting edges.
