kwb ROCKER Concrete and Masonry Drill Bit Diameter 5 mm with High Quality, Temperature Brazed Carbide Plate, Optimal Dust Transport, Hex Shank, Extremely Durable, Complies ISO 5468

High-quality carbide plate: thanks to its high-quality, wide and deep-supported carbide plate, the carbide stone drill from kwb is particularly suitable for impact drilling in concrete, granite, clinker brick and masonry. Hard metal plate high temperature soldered: the carbide plate of the masonry drill and concrete drill is soldered at high temperatures and thus offers an extremely high load capacity in continuous use. EXTREMELY DURABLE: Due to the fact that the drill body of the masonry drill for professionals is made of high-quality chrome-nickel-molybdenum steel, it has a high hardness that is responsible for its extreme durability. Optimal drilling dust transport: the chip-removing, black burnished spiral of the concrete drill is milled and asymmetrically shaped, which ensures extremely fast drilling dust transport for optimal drilling progress. Hexagonal shank: with the hexagonal shank, the hammer-resistant high-performance masonry drill bit from kwb has a particularly good fit in the drill chuck, so that it does not slip even when used in impact drills. According to ISO 5468: The wall breakthrough drill with bare ground surface is manufactured according to the international standard ISO 5468, which defines the drilling geometry.
