kwb Rocker Concrete and Stone Drill Ø 4 Mm with High Quality, Temperature Brazed Carbide Plate, Optimum Dust Transport, Hexagonal 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 well suited for percussion drilling in concrete, granite, clinker and masonry. HARD METAL PLATE HIGH TEMPERATURE SOLDERED: The hard metal plate of the masonry drill and concrete drill is high-temperature soldered and thus offers extremely high resilience in continuous use. EXTREMELY DURABLE: Because the body of the masonry drill for professionals is made of high-quality chrome-nickel-molybdenum steel, it has a high degree of hardness, which is responsible for its extreme durability. OPTIMAL DRILL MILL TRANSPORT: The chip-removing, black burnished spiral of the concrete drill is milled and asymmetrically shaped, ensuring extremely fast drill dust transport for optimum drilling progress. Hexagonal shank: With its hexagonal shank, the hammer-resistant high-performance stone drill 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 masonry breakthrough drill with bright ground surface is manufactured according to the international standard ISO 5468, which defines the drilling geometry.
