Freud DMAMM1090 Carbide Hammer Drill Bit 3/8in Pack of 5

Product Description

The FREUD DMAMM1090 is a multi-material carbide tipped hammer drill bit sized at 3/8 inches in diameter, 4 inches in working length, and 6 inches in overall length, sold in a pack of 5. Engineered under the Diablo line, this bit uses a specialized brazing and hardening process to extend carbide tip life and maintain drilling speed across demanding jobsite materials. The multi-ground grip point tip geometry initiates contact aggressively, producing clean, fast holes from the first rotation. It is suited for licensed tradespeople and skilled installers who need consistent performance across multiple substrate types without changing bits.

This hammer drill bit is designed for use in tile, masonry, concrete, wood, and metal, covering the broad range of substrates encountered in commercial and residential construction and renovation work. The impact-strong shank construction provides stability and durability when paired with both cordless and corded impact drivers and drill drivers, making it a practical choice for electricians, plumbers, HVAC installers, and general contractors who drill through mixed materials on a regular basis.
