Description
The kwb concrete and masonry drill bit in long version has a wide- and deep-supported, high-temperature brazed carbide plate. The chip-removing, asymmetrically shaped drill spiral ensures optimum drill dust transport. While the surface of the masonry drill is brightly ground, the spiral is black burnished. As a hammer-resistant high-performance drill bit, it is suitable for all rotary and impact drills. With a drill bit length of 150 mm, the high-performance drill bit is designed according to ISO 5468 for deep drill holes in granite, concrete, masonry, sand-lime brick, natural and artificial stone.
