kwb ROCKER Stone Concrete Drill Ø 12 mm with High-Temperature Brazed Carbide Plate, Optimum Drill Dust Transport, 200 mm Drill Bit Length and Round Shank, Extremely Durable

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.

• 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 long 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 MORTAR TRANSPORT: The chip-removing, black burnished spiral of the concrete drill in long 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.
• ROUND SHAFT: With the round shank, the impact-resistant high-performance masonry drill bit in long is the ideal accessory for all rotary and impact drills.
