Richard JHHM-300GClick To Copy SDS Rotary Hammer Drill Bit, 1/2" x 21" x 15-1/2", 4-Cutter

The Richard JHHM-300G is an SDS rotary hammer drill bit designed for drilling into tough materials such as concrete and masonry, including applications where rebar may be encountered. This carbide-tipped bit features a 1/2-inch diameter, a 21-inch overall length, and a 15-1/2-inch usable drilling length. Its aggressive 4-cutter head geometry ensures improved drilling performance, longer bit life, and reduces jamming when striking rebar. Integrated wear mark indicators assist in maintaining dimensional accuracy for anchor installations. The bit incorporates rebar chamfers to prevent carbide chipping and a high-volume flute design for efficient dust and debris removal, which also helps to reduce vibration during operation. Given its 1/2-inch diameter, it is most commonly compatible with SDS-Plus rotary hammers, which are typically used for light to medium-duty tasks.
