Innovative drill head and tip geometry with a 25% larger carbide tip for better performance and durability. More aggressive cutting angle allows for up to 20% faster drilling speed. The extra short drill head ensures direct dust entry into the SpiralNut and improved dust removal. The center point prevents wandering. A new extra-deep, asymmetric spiral flute guarantees faster dust removal and shorter drilling times. The body is made of fully hardened chrome vanadium steel for maximum stability and longer service life. Suitable for drilling work in concrete, masonry, brick, concrete block, and granite.
