This IRWIN rotary masonry bit drills concrete, masonry, brick, tile, slate, and plaster. The tungsten carbide tip is diamond-ground to aggressive cutting angles for faster penetration, and a single deep slow-spiral flute clears dust out of the hole to keep the bit cutting and extend its life. The nickel-plated body runs fast and smooth.
