Milwaukee 48-20-9040 Carbide Hammer Drill Bit 5/8x6 in

Product Description

The Milwaukee Electric Tool Corp 48-20-9040 is a carbide hammer drill bit engineered for rotary hammer and hammer drill applications in masonry and concrete. The bit measures 5/8 inch in diameter with an overall length of 6 inches and a flute length of 4 inches, providing adequate depth capacity for anchoring, fastening, and penetration work in block, brick, and poured concrete. The carbide tip construction delivers resistance to wear and heat buildup under sustained percussion loads, extending service life compared to standard steel bits. Sold in a package quantity of 3 units, this bit is a practical stocking item for crews running high-frequency drilling tasks on job sites.

This bit is suited for residential and commercial construction, mechanical rough-in, and concrete anchoring work. It is compatible with corded and cordless hammer drills that accept a standard round-shank or keyed chuck. Typical applications include setting anchor bolts, drilling conduit penetrations through concrete block, and punching through CMU walls during mechanical or electrical rough-in. The 5/8 inch diameter accommodates common anchor sleeve and wedge anchor sizes used in structural and equipment-mounting applications.

Designed as an OEM-style replacement and standard consumable bit for use with hammer drills accepting a standard round-shank chuck configuration in masonry and concrete drilling applications.

Installation Notes

Installation is performed by licensed electricians, plumbers, HVAC technicians, and general construction trades using hammer drills or rotary hammers. Before drilling near existing structural elements, verify the absence of embedded conduit, rebar, or utility lines using a scanner or drawings. Wear appropriate eye and hearing protection during percussion drilling operations. Ensure the drill chuck is fully tightened before beginning to prevent bit slippage and premature tip wear.
