IRWIN 326009 DRL BIT 5/16″ X 4″ X 6″ MASONRY

Experience superior drilling performance with this masonry bit from IRWIN, designed for use with all hammer drills featuring a 3-jaw or Jacobs chuck. Crafted with a chrome vanadium shaft that’s through-hardened to achieve a hardness of 50-53HrC, this bit is engineered to resist breakage and extend its longevity through hot isostatic pressing. The patented flute geometry enhances dust removal, allowing for faster drilling—up to 150% quicker than competing options—while the double-tempered, shot-peened finish further minimizes wear. Additionally, the high-heat resistant copper braze material provides excellent durability and reduces the risk of tip loss, making this bit a reliable choice for any masonry project.
