Milwaukee 48-20-9010 Carbide Hammer Drill Bit 1/4 in

Product Description

The Milwaukee Electric Tool Corp 48-20-9010 is a carbide hammer drill bit designed for use with impact drivers in masonry and concrete drilling applications. Built with a carbide tip, this bit delivers durable cutting performance in hard materials including block, brick, and concrete. The 1/4 inch hex shank seats securely in standard impact driver chucks, making it a practical choice for electricians, plumbers, HVAC technicians, and general trade professionals who need reliable bit performance when drilling anchor or fastener holes in masonry substrates.

This bit is suited for residential and light commercial applications where impact driver compatibility is required. With an overall length of 4 inches and a working diameter of 1/4 inch, it is sized for common anchor and sleeve anchor pilot holes in concrete, block, and brick. It is packaged as a single unit and is a common carry for trade bags and service vans where compact masonry drilling capability is needed without switching to a dedicated hammer drill.

Installation Notes

Installation is performed by licensed tradespeople or qualified technicians using a standard impact driver fitted with a 1/4 inch hex chuck. Ensure the bit is fully seated and locked in the chuck before drilling. When drilling into concrete or masonry, use consistent pressure without forcing the bit to prevent tip damage or bit breakage.
