Solid-carbide drills offer fast penetration time

Emuge Corp. has introduced the EF series solid-carbide drills. They incorporate special geometry, proprietary carbide grades, and a PVD coating design for penetration times that are three to five times faster than conventional carbide and cobalt drills, the company reports.

The drills feature a double-margin flute design for stability and rounder, straighter holes. A flute construction aids chip evacuation, and a self-centering design allows drilling in one shot, eliminating peck cycles and pre-spot operations.

The drills are made of a submicron-grain carbide grade for abrasion resistance and durability. The multilayer PVD coating resists chipping and cracking.
