Irwin 50260 Slow Spiral Flute Masonry Drill Bit, Carbide-Tip

The Irwin Slow Spiral Flute Masonry Drill Bit is built for fast, clean drilling into concrete and brick on jobsites and renovation projects. This masonry bit family is available in 7/16", 1/2", 5/8", and 3/4" diameters, each with a 6" overall length, and pairs a diamond-ground tungsten carbide tip with a deep single spiral flute that clears dust and debris quickly to keep the bit cutting efficiently through demanding masonry substrates. The tungsten carbide tip resists wear and chipping when drilling repeatedly into concrete and brick, helping the bit hold its edge over extended use.
