Freud DMAMM1120 Multi-material Hammer Drill Bit 1/2in

Product Description

The FREUD DMAMM1120 is a carbide tipped hammer drill bit engineered for multi-material applications across tile, masonry, concrete, wood, and metal. Measuring 1/2 inch in diameter with a 4-inch flute length and 6-inch overall length, this bit is built for trade professionals who need reliable performance across varied substrates on the same job. The carbide tip is processed through a specialized brazing and hardening method that extends working life and maintains cutting speed over repeated use. The multi-ground grip point tip geometry initiates contact aggressively, producing clean, fast holes with minimal wandering at start.

This hammer drill bit is suited for residential and commercial construction, renovation, and mechanical installation work where drilling through mixed or unknown materials is common. The shank is impact-rated for use in both corded and cordless hammer drills and impact drivers, giving installers flexibility across tool platforms. Electricians, plumbers, HVAC technicians, and general contractors will find this bit performs consistently when core drilling through composite assemblies or penetrating masonry and tile in retrofit scenarios.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary and hammer drilling procedures. Confirm the drill chuck is fully tightened and the tool is set to the correct mode before operation. Always wear eye protection and appropriate PPE when drilling into masonry or tile. Inspect the bit tip for wear or damage before each use and replace if carbide shows chipping or degradation.
