Richard JHHM-300AClick To Copy 4-Cutter Hammer Drill Bit, 1/2" Diameter, 13" Overall, 7-1/2" Working Length

The Richard JHHM-300A hammer drill bit, with a 1/2-inch diameter, 13-inch overall length, and 7-1/2-inch working length, is designed for efficient drilling in challenging materials such as concrete, masonry, and reinforced concrete. It features an aggressive 4-cutter carbide head geometry, which enhances drilling performance and extends tool life, while also preventing lock-up when encountering rebar. Rebar chamfers protect the carbide from chipping, and wear mark indicators ensure dimensional accuracy, which is critical for anchor fitting installations. A high-volume flute design optimizes dust and debris removal, and its construction aims to reduce vibration for improved operator comfort and reduced stress on the drill motor.
