Bosch HCFC5020 Rotary Hammer Drill Bit, 5/8 in Dia, 13 in L, 8 in L Flute, 1/2 in Dia Shank, Carbide, 4-Flute

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 versus 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 deg cutting diameter and 100% power transfer during drilling. The active centering tip results in rounder hole, while the four 90 deg 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.
