IRWIN 326006 DRL BIT 1/4″ X 4″ X 6″ MASONRY

Engineered for exceptional performance in demanding masonry applications, this concrete bit stands out with its shot-peened and double-tempered finish that minimizes breakage while enhancing durability. The through-hardened chrome vanadium shaft, rated at 50-53HrC, provides a robust foundation, compatible with all hammer drills equipped with a 3-jaw or Jacobs chuck. Its patented flute geometry is designed to efficiently remove dust from the hole, allowing for quicker drilling speeds—up to 150% faster than competing products—while maintaining a long lifespan. Additionally, the use of high-heat resistant copper braze material ensures that the tips remain securely in place, making this an indispensable tool for both professionals and DIY enthusiasts tackling concrete projects.
