The MILWAUKEE® SDS Plus Rebar Cutters are the toughest in rebar, delivering up to 3x life in rebar compared to competitive rebar cutters. These bits, designed with precision ground carbide for rebar only drilling, provide up to 10x faster drilling speeds in rebar vs. 4-cutter drill bits. Milwaukee SDS Plus Rebar Cutters are equipped with HAMMER GUARD™ protective shanks, preventing carbide teeth destruction from accidental use in rotary hammer mode, saving time and money. Deep debris channels provide the fastest rebar shard removal while double ejection slots allow for easy rebar slug removal. Available in sizes 3/8” – 1-1/2”, Milwaukee SDS Plus Rebar Cutters are the optimal solution for drilling embedded rebar for corded and cordless SDS Plus rotary hammers. For use in rebar only.
