Bosch 1/2" x 8" x 13" SDS-Max SpeedXtreme Rotary Hammer Drill Bit

Bosch 1/2" x 8" x 13" SDS-Max SpeedXtreme Rotary Hammer Drill Bit is engineered for exceptional durability and performance in reinforced concrete and hard aggregate. Featuring 100% carbide heads with a unique four-cutter design, these drill bits offer unmatched toughness and longevity, providing five times the life compared to competing products. Crafted using Bosch’s proprietary diffusion-bonding technology, the carbide and steel are fused at a molecular level through a precise high-heat, high-pressure solid-state welding process, ensuring jobsite-proven reliability. Bosch stands out as the only concrete bit manufacturer to produce its own carbide and perform 100% quality checks on every single bit. The four-cutter design delivers a 180° cutting diameter with 100% power transfer for efficient drilling. An active-centering tip ensures rounder holes, while the four 90° side angles create a wide, sharp head that maintains precision during use. Additionally, the four-flute design aggressively evacuates dust from the work area, enabling faster drilling and extending bit life.
