Hillman 375224 Tapcon Masonry Drill Bit 3/16 X 4-1/2 In.

Product Description

The HILLMAN 375224 is a carbide-tipped masonry drill bit designed for use with Tapcon-style concrete anchors. It bores clean, accurate pilot holes into concrete, block, and masonry surfaces, giving fasteners a solid bite from the start. The 135-degree split-point tip reduces walking on contact and improves drilling control in hard substrates. At 0.056 pounds, the bit is lightweight and easy to handle in tight spaces. Licensed contractors and trade professionals use this bit when anchoring fixtures, brackets, and equipment to structural masonry.

This bit is suited for residential and light commercial applications where Tapcon-style anchors are specified. Typical installation scenarios include securing electrical conduit straps, plumbing hangers, HVAC equipment bases, and similar hardware to poured concrete or CMU block walls. The 3/16-inch diameter matches the standard pilot hole requirement for corresponding Tapcon anchor diameters used in those applications.

Compatibility

Installation Notes

Installation is typically performed by electricians, plumbers, or HVAC technicians anchoring equipment or supports to masonry surfaces. Use a hammer drill set to rotation-plus-hammer mode for best results in concrete or block. Wear appropriate eye and respiratory protection when drilling masonry. Confirm anchor embedment depth requirements before drilling to avoid under-depth holes.
