Bosch 1" x 16" x 21" SDS-Max SpeedXtreme Rotary Hammer Drill Bit

Bosch 1" x 16" x 21" SDS-Max SpeedXtreme Rotary Hammer Drill Bit is designed to deliver exceptional durability and performance for drilling in reinforced concrete and hard aggregate. Featuring 100% carbide heads with a unique four-cutter design, these bits offer five times the lifespan compared to the competition. 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 jobsite-proven reliability. Bosch is the only manufacturer to produce its own carbide and performs a 100% quality check on every bit. The bit’s four-cutter design provides a 180° cutting diameter and ensures 100% power transfer during drilling. Its active-centering tip creates rounder holes, while the four 90° side angles form a wide, sharp head for precise hole driving. Additionally, the four-flute design efficiently removes dust for faster drilling and extended bit life. Model Number: 1 608 594 034
