Disston Company 691188 Masonry Drill Bit 3/16 X 4 in

Product Description

The DISSTON COMPANY 691188 is a carbide-tipped, rotary percussion masonry drill bit designed for use in standard drills with rotary or hammer mode. Measuring 3/16 inches in diameter and 4 inches in overall length, this bit features a black oxide finish and a carbide tip brazed to handle the high-impact demands of masonry drilling. It is suited for licensed tradespeople and experienced DIYers who need a reliable masonry bit for everyday drilling tasks in common building materials. The carbide tip extends service life compared to standard steel bits when working through abrasive substrates.

This bit is recommended for drilling cinder block, common brick, hard brick, plaster, ceramic tile, glazed tile, and wet or dry concrete. It is also suitable for moderate use in marble, granite, and concrete rated over 6000 psi. The rotary percussion design makes it compatible with both standard rotary drills and drills equipped with a hammer mode, giving it flexibility across job sites where multiple material types are encountered in a single session.

Installation Notes

Installation is typically performed by electricians, plumbers, HVAC technicians, or general construction tradespeople when anchoring fasteners or running penetrations through masonry walls. Always wear appropriate eye and respiratory protection when drilling masonry. Confirm wall cavity contents before drilling to avoid contact with concealed conduit, pipe, or structural elements. Use the drill manufacturer's recommended speed setting for the bit diameter and material being drilled.
