Product description: These innovative hammer drills with solid carbide drill tip offer users the highest performance in the toughest applications. Superior tungsten carbide alloy and borehole geometry provide greater resistance to breakage and higher abrasion resistance to ensure maximum durability and service life. The design with 4 cutting edges achieves a maximum concentricity of the drill holes, as a result of which fastenings have a higher tensile strength. Optimal design of the 4-way drain for efficient grit removal and higher durability.
