SDS-Plus concrete drill bit SUPER 5x110mm professional solid cross plate Kranz KR-91-0450

Super concrete drill bit is designed for professional intensive use. It is used during construction and renovation work for intensive drilling of holes in reinforced concrete, granite, brickwork and stone using a rotary hammer with SDS PLUS attachment. The working part of the drill bit is made of a solid carbide plate, which makes it resistant to heavy impacts and high temperatures. The cross shape of the plate ensures high drilling speed and reliable protection when hitting reinforcement. Diffusion welding guarantees heat resistance and prevents plate destruction, ensuring maximum service life and performance. Optimized design with four grooves quickly removes dust, maintaining cooling of the carbide head. Thanks to the precision tip, the drill bit possesses the stability and accuracy required for creating fast and neat holes. Drill body material – tool steel (40cr). Drill tip insert material – carbide alloy (YG8C).
