Hillman 375223 Tapcon Masonry Drill Bit 3/16 X 3-1/2 in

Product Description

The HILLMAN 375223 is a carbide-tipped Tapcon masonry drill bit designed for drilling pilot holes in concrete, block, and other masonry materials. The 135-degree tip angle helps center the bit on contact and reduces walking at the start of the hole. At 3/16 inch in diameter and 3-1/2 inches in length, this bit is sized specifically for use with standard Tapcon-style concrete anchors. It is a single-use or limited-use consumable tool handled by masons, concrete contractors, HVAC installers, electricians, and plumbers who anchor equipment or conduit to masonry surfaces.

This drill bit is suited for residential and light commercial applications where Tapcon or similar flat-head hex washer-head concrete screws are used to fasten brackets, straps, junction boxes, equipment pads, and similar hardware to poured concrete, concrete block, or brick. The 3/16-inch diameter matches the pilot hole requirement for standard 3/16-inch Tapcon anchors, making it a direct pairing for that fastener size.
