Freud DMARG1220-S5 Carbide Hammer Drill Bit Set 5pc

Product Description

The FREUD DMARG1220-S5 is a 5-piece Speed Demon red granite carbide tipped hammer drill bit set designed for fast, accurate drilling in concrete, masonry, and stone. Each bit features a carbide tip optimized through a proprietary brazing and hardening process that extends tip life and maintains drilling speed under heavy use. The multi-ground grip point tip design promotes aggressive starts and produces clean holes with minimal chipping. The set is impact strong, meaning the shank geometry is engineered for increased stability and durability when used in both cordless and corded impact drivers and hammer drills. Licensed electricians, plumbers, HVAC techs, and general contractors rely on this type of set for anchoring and penetration work through concrete substrates.

This set is suited for residential and light commercial applications where drilling through concrete slabs, block walls, brick, or natural stone is required. The five included bits cover the most common anchor and fastener bore sizes used in trade work. The set works with standard hammer drills and corded or cordless impact drivers, making it a versatile addition to a service truck or job site kit. Included sizes are 5/32 inches x 4 inches x 6 inches, 3/16 inches x 4 inches x 6 inches, 1/4 inches x 4 inches x 6 inches, 5/16 inches x 4 inches x 6 inches, and 3/8 inches x 4 inches x 6 inches.

Installation Notes

These bits are installed and used by licensed tradespeople and experienced contractors performing anchor, conduit, and pipe penetration work through concrete and masonry. Always wear appropriate eye protection and dust control measures when drilling into concrete or masonry. Confirm the drill is set to hammer mode when drilling into hard substrates. Inspect carbide tips for chipping or wear before each use and replace any bit that shows tip damage to avoid inaccurate holes or shank failure.
