Irwin Industrial Tool Co 5026009 Masonry Drill Bit 3/8x4 in

Product Description

The IRWIN INDUSTRIAL TOOL CO 5026009 is a professional-duty masonry drill bit designed for percussion and rotary drilling in concrete, brick, and similar masonry materials. The bit measures 3/8 inches in diameter by 4 inches in length and features a tungsten carbide tip brazed for durability under repeated impact. A slow spiral, deep single-flute design channels drilling dust and debris out of the hole quickly, reducing heat buildup and keeping the cut clean. The bit is nickel plated to reduce friction and promote smooth performance during extended use. This package contains 5 individual bits. Licensed tradespeople and skilled installers working in masonry anchor, conduit, or mechanical fastener applications will find this format practical for jobsite use.

These bits are suited for drilling anchor holes, conduit penetrations, and mechanical fastener points in residential and light commercial masonry construction. They function in standard rotary drills as well as hammer drills operating in percussion mode. For bits 7/16 inches and larger in this product line, reduced shanks are used to allow fitment in standard 3/8-inch chuck drills. The 3/8-inch diameter covered here uses a standard shank. Typical applications include setting anchor bolts, running electrical or plumbing penetrations through block or brick, and general masonry fastening work performed by electricians, plumbers, HVAC installers, and general contractors.

Installation Notes

Masonry drill bits of this type are installed and used by electricians, plumbers, HVAC technicians, and general contractors working with concrete or brick substrates. Always confirm the drill chuck size matches the bit shank before use and verify no embedded conduit, rebar, or utilities are present in the drilling path. Use appropriate eye and respiratory protection when drilling masonry. Allow the bit to cool between extended drilling sequences to preserve carbide tip integrity.
