Milwaukee 7-PC SDS Plus M/2™ 2-Cutter Concrete Screw Installation Kit contains everything needed to install common flat head and hex head screws into concrete, brick, and cinder block. These SDS Plus Bits with 1/4-inch Hex are specially designed for Tapcon® screw applications. Featuring a 2-cutter geometry, they enable faster drilling and efficient debris removal while the centering tip enhances accuracy. The reinforced flutes improve impact resistance and effectively transfer energy to the bit tip for superior performance. Additionally, the incorporated rebar chamfers help withstand hard impacts from rebar and tough aggregate, reducing carbide chipping for longer bit life.
