The Milwaukee® SDS Plus Bits with 1/4" Hex are designed specifically for Tapcon® screws. Built to take on brick, block, and concrete the bits feature 2-cutter geometry for fast drilling and debris removal. The reinforced flute design increases impact resistance and transfers energy directly to the bit tip while rebar chamfers withstand impacts from rebar and hard aggregate while reducing carbide chipping. To be used with Drive Sleeve available in the SDS-Plus Tapcon® Installation Kit (48-20-7497). Tapcon® is a registered trademark of Illinois Tool Works Inc.
