Milwaukee 48-20-9030 Carbide Hammer Drill Bit 1/2x6 in

Product Description

The Milwaukee Electric Tool Corp 48-20-9030 is a carbide-tipped hammer drill bit engineered for drilling into concrete, brick, and masonry. It measures 1/2 inch in diameter with a 4-inch working length and 6-inch overall length. The bit features a reinforced POWER TIP carbide head designed to resist wear and maintain cutting speed through hard aggregate materials. Compatible with both standard rotary hammer drills and impact drivers, this bit is suited for HVAC, plumbing, and electrical rough-in work where anchoring into masonry is required. It ships in a package quantity of 3 per unit of measure.

This bit is intended for use in residential and light commercial applications where tradespeople need to bore clean, accurate holes through concrete block, poured concrete, or brick. Common tasks include setting anchor bolts, running conduit sleeves, installing pipe penetrations, and mounting equipment to masonry walls. Its impact-driver-capable shank design adds flexibility on jobsites where a dedicated rotary hammer is not available.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary hammer or impact driver operation. Wear appropriate eye and respiratory protection when drilling masonry, as silica dust is a respiratory hazard. Ensure the drill is set to hammer mode when using a rotary hammer, and do not apply lateral force to the bit during drilling. Confirm all penetrations comply with applicable building codes before sealing or anchoring.
