Bosch 7/8" x 8" x 13" SDS-Max Speed Xtreme Rotary Hammer Bit

Bosch 7/8" x 8" x 13" SDS-Max Speed Xtreme Rotary Hammer Bit delivers exceptional durability and performance with its 100% carbide heads and innovative four-cutter design. Engineered for drilling in reinforced concrete and hard aggregate, this bit offers five times the life compared to competitors. Utilizing proprietary diffusion-bonding technology, Bosch bonds carbide and steel at a molecular level through a precise high-heat, high-pressure solid-state welding process, ensuring jobsite-proven reliability. As the only concrete bit manufacturer to produce its own carbide, Bosch guarantees 100% quality checks on every bit. The four-cutter design provides a 180° cutting diameter and complete power transfer during drilling, while the active-centering tip creates rounder holes. Additionally, the four 90° side angles form a wide, sharp head that maintains precise hole driving. Its four-flute design efficiently pulls dust away from the work area, enabling fast drilling and extending bit life. Model Number: 7/8" x 8" x 13"
