Bosch 3/4 In. x 16 In. x 21 In. SDS-max SpeedXtreme Rotary Hammer Drill Bit

Bosch SpeedXtreme? SDS-max? 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.
