Hoffmann Group USA has expanded its Garant MasterSteel solid carbide drill product series with the three-edged, solid carbide drill and matching three-edged NC spotting drill, including 8×D and 12×D variants.
The drills address chip removal challenges of three-edged drills and promote high feed rates, the company says. The cutting edge geometry is designed to create stability and a large clearance in the center. The taper’s tip angle is also designed to reduce cutting pressure for optimal chip flow and controlled chip breaking.
A matching NC spotting drill is designed to precisely perform deep drilling. The self-centering capability enables targeted spot drilling even on critical and uneven surfaces. The point geometry is optimally matched to the geometry of the company’s Feed drill with a point angle of 155 degrees. These products offer up to 50 percent more feed per rotation, according to the company.
