Hillman 375220 Tapcon Masonry Drill Bit 5/32 X 3.5 in

Product Description

The HILLMAN 375220 is a carbide-tipped Tapcon masonry drill bit designed for driving Tapcon-style concrete anchors into hard masonry surfaces including concrete, block, and brick. The bit features a 135-degree tip angle that helps center the bit on contact and reduces walking on hard surfaces. At 5/32 inch in diameter and 3.5 inches in length, it matches the pilot hole specification required for standard Tapcon fastener installations. Licensed tradespeople and experienced installers use this bit when anchoring fixtures, brackets, or hardware directly into masonry substrates.

This drill bit is suited for residential and light commercial applications where Tapcon-style concrete screw anchors are specified. Typical install scenarios include anchoring electrical conduit supports, mechanical equipment bases, framing ledgers, and similar structural or utility attachments to poured concrete or concrete masonry unit walls and floors. The 5/32 inch diameter is the standard pilot hole size for 3/16 inch Tapcon screws.

Key Features

• Carbide tip construction for extended durability in hard masonry materials
• 135-degree tip angle for improved bit centering and reduced walking
• 5/32 inch diameter matched to standard 3/16 inch Tapcon screw pilot hole requirements
• 3.5 inch overall length provides adequate depth clearance for typical anchor installations

Compatibility

Designed for use with standard 3/16 inch Tapcon-style concrete screw anchors in concrete, block, and brick masonry applications.

Installation Notes

Installation is typically performed by a qualified tradesperson using a hammer drill set to rotary-hammer mode. Always disconnect or de-energize any embedded utilities before drilling into existing masonry. Drill to the required depth per the anchor manufacturer specification and clear debris from the hole before driving the fastener. Follow applicable building codes and anchor manufacturer guidelines for minimum edge distance and embedment depth.
