Milwaukee Tool 48-20-7533 Sds-plus Drill Bit 1/4 in

Product Description

The MILWAUKEE TOOL 48-20-7533 is a carbide-tipped SDS-Plus rotary hammer drill bit designed for drilling into concrete, masonry, and block. The 1/4 inch diameter bit features a chisel cutting geometry and a high-speed steel body with a carbide-tipped cutting edge, delivering the impact resistance needed for rotary hammer applications. With a 9-inch usable length and a 10-inch overall length, it reaches into deeper anchor holes and through-hole applications common in commercial and residential construction. This bit meets ANSI B212.15 standards and is sold as a single piece.

This bit is suited for use with SDS-Plus rotary hammers across residential and commercial job sites. Typical applications include setting anchor bolts, drilling conduit penetrations, and boring through concrete slabs, CMU walls, and poured foundations. Electricians, plumbers, HVAC installers, and general contractors all reach for SDS-Plus bits when core drilling or anchor setting in hard substrates. The 1/4 inch diameter matches common anchor and sleeve anchor sizes used in mechanical and electrical rough-in work.

Designed for use with SDS-Plus rotary hammers. The SDS-Plus shank is an industry-standard interface compatible with SDS-Plus chuck systems from major rotary hammer manufacturers.

Installation Notes

SDS-Plus drill bits are installed and removed by licensed tradespeople and experienced operators using SDS-Plus rotary hammers — no chuck key is required. Before drilling near existing structure, verify the absence of embedded conduit, rebar, or post-tension cable using a scanning tool. Always wear eye and hearing protection when operating a rotary hammer. Follow applicable OSHA silica dust regulations when drilling concrete or masonry, including use of wet drilling methods or HEPA vacuum extraction where required.
