The Milwaukee 48-20-7497 is a comprehensive 7-piece installation kit designed for drilling and driving concrete screws using a single SDS-PLUS rotary hammer. The kit features M2 2-cutter SDS-PLUS masonry bits with a 1/4-inch hex shoulder, specifically engineered for Tapcon-style screw applications in concrete, brick, and block. It includes two carbide-tipped drill bits (5/32" x 7" and 3/16" x 7"), a drive sleeve, two magnetic SHOCKWAVE Impact Duty nut drivers (1/4" and 5/16"), and two 2-inch Phillips driver bits (#2 and #3). The system utilizes a recessed shoulder on the nut drivers to prevent over-torquing and screw snapping, while the drive sleeve allows for rapid transitions between drilling and fastening without removing the bit from the chuck
