IRWIN 323006 DRL BIT 5/8″ X 15 1/2″ X 21″ SDS-MAX 4C

Engineered for superior performance, this drill bit combines advanced materials and thoughtful design to enhance your drilling experience. The shot-peened and double-tempered finish not only reduces breakage but also ensures durability on tough projects. Designed to fit all SDS-Max rotary hammers, including Hilti models, it is ideally suited for concrete drilling. The specially formulated copper braze material enhances heat resistance, minimizing tip loss during intensive use, while the chrome vanadium shaft is through-hardened, providing exceptional strength. Additionally, the patented flute geometry efficiently removes dust from holes, facilitating faster drilling and extending the life of the bit, making it a reliable choice for contractors and DIY enthusiasts alike.
