BOSCH HCFC5011 1/2 in. x 16 in. x 21 in. SDS-max SpeedXtreme Full Head Carbide Rotary Hammer Drill Bit

• Long-lasting SDS-Max drill bit design – manufactured with 100% Carbide head and four-cutter design, making it the long-lasting bit for drilling in reinforced concrete and hard aggregate
• Latest diffusion-bonding technology – Provides 5x life vs. Competition, For the strongest bond available
• Four-cutter head design – provides 180° cutting diameter and 100% power transfer during drilling
• Four symmetrical 90° side angles – create a wide and sharp tip to aggressively cut through tough material like concrete with rebar
• Active-centering tip – results in rounder holes for precision-anchoring applications, with a wear mark to help deliver precision hole-diameter tolerance

BOSCH SpeedXtreme SDS-Max drill bits deliver 100% carbide heads with four-cutter design, making them the toughest, long-lasting bits for drilling in reinforced concrete and hard aggregate. The bits provide 5x life vs. Competition. The bits are engineered using proprietary diffusion-bonding technology, which bonds carbide and steel at a molecular level. It’s a precise high-heat, high-pressure solid-state welding process that produces jobsite-proven bits. BOSCH is the only concrete bit manufacturer to make its own carbide, and 100% Quality check on each and every single bit. The bit has a four-cutter design with 180° cutting diameter and 100% power transfer during drilling. The active-centering tip results in Rounder hole, while the four 90° side angles create a wide and sharp head keep driving precise holes. The four-flute design aggressively pulls dust away from the work, for fast drilling and longer bit life.
