Over the years, BOSCH has brought constant innovation to concrete and masonry drilling. From inventing the industry standard SDS system, to in-house manufacture of carbide optimised for percussion drilling, and perfecting diffusion bondng technology that results in improved performance and enhanced durability, BOSCH is the global leader. - BOSCH 's latest ground-breaking innovation is the BULLDOG XTREME . These bits provide incredible durability with a lifetime up to 3X that of the nearest competitor, especially when hitting embedded reinforcing bar. The exceptional durability is thanks to a full carbide head featuring four cutters and matching flutes. - The heads are connected with proprietary diffusion bonding technology. Diffusion bonding's high-heat, high-pressure, solid-state welding, produces an incredibly strong bond which ensures the heads stay on even during the toughest applications where multiple rebar strikes occur. - BULLDOG XTREME Bits also feature a wear mark which when still visible ensures the bit is drilling to the stated diameter. This is very important due to the tight tolerences required from various masonry anchor systems. - All BULLDOG XTREME Bits are proudly Made in Germany.FeaturesSolid Carbide Head - For XTREME durability4-Cutter / Flute Geometry - For XTREME speed - Centric Conical Tip - Results in rounder, more accurate holes which is important in anchoring applications - Wear Mark - When visible, ensures bit is drilling to the stated diameter - PGM Certification - Ensures bit's stated diameter is accurate at the time of manufactureSpecificationsDiameter: 10.0 mm - Working Length: 100 mm - Overall Length: 165 mm - Cutter Configuration: 4-Cutter - Solid Carbide - Shank: SDS-PlusIncludesBULLDOG XTREME Bits (x10)Plastic Storage Tube
