The Milwaukee 48-20-7430 is a 1/4-inch SDS Plus rotary hammer drill bit designed for fast, efficient drilling in concrete and masonry. Part of Milwaukee's M/2™ 2-cutter line, this bit combines advanced cutting geometry with reinforced construction to deliver up to 20% more holes per charge in cordless rotary hammers while performing reliably in both corded and cordless applications.

The bit's breaker point design results in faster drilling speeds. The variable flute allows for maximum debris extraction, keeping the bit performing well in cordless and corded rotary hammers alike. A centering tip ensures precise spot drilling, while enhanced rebar guards protect against premature wear when drilling through reinforced concrete. A wear mark indicator shows when the bit no longer meets ANSI diameter requirements, helping you know when replacement is needed.
