Disston Company 120782 Masonry Drill Bit 3/16 X 4 Inch

Product Description

The DISSTON COMPANY 120782 is a 3/16-inch by 4-inch masonry drill bit with a straight shank, designed for drilling into a wide range of masonry materials. The carbide-style tip handles the abrasive demands of cinder block, common brick, plaster, ceramic tile, and wet concrete. This bit is packaged as a single carded unit, suited for light-duty and occasional masonry work on residential and light commercial job sites. Tradespeople and knowledgeable DIYers reach for this size when anchoring into masonry walls, setting fasteners, or prepping penetrations through tile and block.

This bit is recommended for drilling cinder block, common brick, plaster, ceramic tile, and wet concrete. It is rated for occasional use in harder materials such as hard brick, glazed tile, and dry concrete. The 3/16-inch diameter is a common size for anchor and fastener applications across plumbing, electrical, and HVAC rough-in work where small-diameter masonry penetrations are required.

Installation Notes

Installation is performed by electricians, plumbers, HVAC technicians, and general tradespeople requiring masonry penetrations. Always wear eye protection and a dust mask when drilling masonry. Use a variable-speed drill at a moderate speed without hammer mode when working in ceramic tile or plaster to reduce the risk of cracking. Allow the bit to cool periodically during extended use to preserve tip integrity.
