kwb Hardcut Granite Drill Ø 12 Mm with Special Carbide Cutting Edge, Asymmetric, High-Temperature Brazed Carbide Plate, Optimum Drill Dust Transport and Round Shank, Extremely Durable

• SPECIAL HARD METAL CUTTING EDGE: Thanks to its diamond-ground hard metal cutting edge, the hard metal masonry drill from kwb has a very high hardness for reliable work in the hardest materials, such as concrete, granite, slate, gneiss, basalt and hard-fired tiles.
• ASYMMETRIC TUNGSTEN CARBIDE PLATE: Due to the asymmetrically shaped tungsten carbide plate of the concrete drill, optimum drilling progress is also possible when using drills and cordless drills without impact drilling equipment.
• 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.
• OPTIMAL DRILL MILL TRANSPORT: The special V-shape of the milled spiral of the granite drill enables extremely fast transport of the drill dust and thus ensures optimum drilling progress.
• 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.

The kwb AKKU-TOP granite drill bit is ideal as a drill bit for hard materials such as granite, gneiss, slate, basalt, glass, ceramics, roof tiles and concrete thanks to its diamond-ground special carbide cutting edge, the high tungsten carbide content and its homogeneous fine-grain structure. The resulting drill dust is optimally removed thanks to the asymmetrically shaped drill spiral. The kwb granite drill is ISO 5468 compliant, has a point angle of 120° and is used at a recommended speed of 800-1,000 rpm without impact.
