Irwin 326023 Masonry Drill Bit, 3/4 In. Dia, 12 In. Oal, Rotary Hammer

The Irwin 326023 is a professional-grade masonry drill bit designed for rotary hammer drills and percussion drilling into tough materials like concrete, brick, and stone. With a 3/4-inch diameter and 12-inch overall length, this bit delivers the reach and power needed for deep drilling applications in thick walls, slabs, and solid masonry. Whether you're a contractor tackling large projects or a homeowner making home improvements, this bit provides the precision and reliability required for demanding drilling tasks.

The chrome vanadium shaft is through-hardened to 50–53 HrC, shot-peened, and double-tempered to resist heat and wear during extended drilling. The copper braze material at the tip provides exceptional heat resistance, while the two-flute geometry efficiently evacuates dust and debris from the hole, promoting faster drilling and extending bit life. This bit fits all hammer drills equipped with 3-jaw or Jacobs chucks, making it compatible with a wide range of equipment.
