3/16" X 4" Installer Bit 1870567-SBD

Irwin’s Installer Bit is a 3/16 in diameter, 4 in long masonry drill bit designed for precise and reliable concrete fastening. Its 2-flute spiral carbide tip with black oxide finish delivers fast, clean, and accurate holes for Tapcon® screws and other concrete fasteners. The built-in hex collar serves as a stop to ensure perfect hole depth, while the drill/drive installation sleeve slides over the bit to quickly drive hex or Phillips head screws. The 1/4 in quick-change shank is compatible with impact drivers and reduces slipping in standard drill chucks, and the one-piece construction withstands higher torque loads than standard quick-change bits, making it ideal for professional contractors and DIY enthusiasts working with concrete, brick, or block.
