Bosch 7/8" x 31" x 36" SDS-Max Speed Xtreme Rotary Hammer Bit

Bosch 7/8" x 31" x 36" SDS-Max Speed Xtreme Rotary Hammer Bit delivers unmatched durability and performance for drilling in reinforced concrete and hard aggregate. Featuring 100% carbide heads with a four-cutter design, this bit stands out as one of the toughest and longest-lasting options available. Engineered with 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 superior strength and reliability on the jobsite. As the only concrete bit manufacturer to produce its own carbide and conduct a 100% quality check on every bit, Bosch guarantees exceptional product quality. The four-cutter design offers a 180° cutting diameter and 100% power transfer during drilling, while the active-centering tip creates a rounder hole. Additionally, the four 90° side angles form a wide, sharp head that maintains precise hole driving. The innovative four-flute design efficiently removes dust from the drilling area, enabling faster drilling and extending the bit’s life for demanding applications. Model Number: 7/8 x 31 x 36
