Disston Company 702615 Masonry Drill Bit 5/32x4 in

Product Description

The DISSTON COMPANY 702615 is a carbide-tipped rotary percussion masonry drill bit designed for use in standard drills operating in rotary or hammer mode. Measuring 5/32 inches in diameter and 4 inches in length, this bit features a black oxide finish and a carbide tip engineered to penetrate hard masonry surfaces without excessive wear. It is a carded, single-piece bit suited for trade professionals and skilled tradespeople who need a reliable, compact masonry bit for light to moderate drilling tasks on jobsites or in the field.

This bit is recommended for drilling cinder block, common brick, hard brick, plaster, ceramic tile, and glazed tile. It also performs in wet or dry concrete applications and is rated for moderate use in marble, granite, and concrete exceeding 6000 psi. The 5/32-inch diameter makes it well suited for anchor pilot holes, fixture mounting points, and similar small-diameter masonry penetrations in both residential and light commercial settings.

Installation Notes

This bit is typically installed and used by HVAC technicians, plumbers, electricians, and general contractors drilling anchor or fastener pilot holes in masonry substrates. Confirm the drill is set to the correct mode before beginning — rotary for softer masonry, hammer mode for harder concrete and brick. Keep steady, consistent pressure and allow the carbide tip to do the cutting; forcing the bit can cause tip damage or bit breakage. Always wear appropriate eye and respiratory protection when drilling masonry materials.
