Large L/D Ratio Drills Guarantee Excellent Feed Rates with Controlled Chip Removal

The GARANT MasterSteel solid carbide drill product series with the SPEED and FEED high performance solid carbide drills from Hoffmann Group USA (Knoxville, TN) has been expanded further with the three-edged, solid carbide drill and matching three-edged NC spotting drill. This tool family now includes the variants 8xD and 12xD, the world’s largest L/D ratio. Chip removal is a challenge when it comes to three-edged drills. Nonetheless, the MasterSteel FEED 8xD and 12xD have been successfully designed with guaranteed excellent feed rates that are ensured by a special cutting-edge geometry with stable cutting edges and a large clearance in the center. A special taper with a special shaped tip angle reduces the cutting pressure and creates an optimal chip flow, as well as controlled chip breaking.

In addition to the MasterSteel FEED, a matching NC spotting drill has been developed to carry out deep drilling precisely. The self-centering capability allows for targeted spot drilling, even on critical and uneven surfaces. Its point geometry is optimally matched to the geometry of the MasterSteel FEED drill with a point angle of 155 deg. These tools offer up to 50 percent more feed per rotation with a state-of-the-art coating technology. These MasterSteel tools can be ordered on their website from the Hoffmann Group USA E-Shop.
