The high-performance TE-YX drill bit for concrete is available in two versions, featuring a head with either six or four cutting edges. The newly designed head with six cutting edges for diameters in the 35–55 mm range provides consistent high performance and less catching and jamming when striking steel reinforcing bars. The classic four-edged drill bit features narrower helical flutes and even more durable cutting edges than its predecessors. A special design feature of the flutes is the company logo, which runs all the way around.
