Disston Company 120881 Masonry Drill Bit 1x6 in Extra Length

Product Description

The DISSTON COMPANY 120881 is a 1-inch diameter, 6-inch extra-length masonry drill bit designed for rotary drilling into masonry and concrete substrates. The bit features a 1/2-inch shank and a positive point angle geometry that allows quick, accurate penetration into the work surface. A zinc surface finish provides basic corrosion resistance during storage and use. This bit is suited for use by contractors, maintenance technicians, and trade professionals who need reliable material removal in common masonry applications without requiring a hammer-drill or SDS chuck.

This bit is recommended for drilling cinder block, common brick, plaster, and ceramic tile. It is rated for moderate use in harder substrates including hard brick, glazed tile, and dry concrete. The extra-length body at 6 inches allows access to deeper holes or setbacks where a standard-length bit would not reach. Typical installations include anchor setting, conduit penetrations, and fixture mounting in masonry walls and partitions found in both residential and light commercial construction.

Installation Notes

Install and remove the bit with the drill unplugged or the battery removed. Secure the 1/2-inch shank firmly in the chuck before operation. Use steady, consistent feed pressure and allow the bit to clear debris periodically to prevent overheating. Follow applicable OSHA and job-site safety requirements when drilling into masonry, including eye and respiratory protection to guard against dust and spalling.
