Disston Company 120824 Masonry Drill Bit 7/16 X 6 in Extra Length

Product Description

The DISSTON COMPANY 120824 is an extra-length masonry drill bit designed for boring through common masonry materials in construction and renovation applications. The bit measures 7/16 inches in diameter with a 6-inch working length and features a 1/4-inch shank for compatibility with standard drill chucks. A positive point angle geometry allows for quick, accurate penetration into masonry surfaces, reducing the tendency to walk on hard or uneven faces. The zinc surface finish provides a degree of corrosion resistance during storage and use. This bit is suited for trade professionals and skilled tradespeople who need reliable masonry drilling performance on everyday job sites.

The 120824 is recommended for drilling cinder block, common brick, plaster, and ceramic tile. It is also rated for moderate use in harder materials such as hard brick, glazed tile, and dry concrete. The extra 6-inch length gives added reach for penetrating thicker walls or drilling through masonry where a standard-length bit would fall short. This bit is typically used by masons, general contractors, electricians, and plumbers who need to run conduit, pipe, or anchors through masonry assemblies.

Installation Notes

Masonry drill bits of this type are installed by general contractors, electricians, plumbers, and masons working with rotary or hammer drills. Always wear appropriate eye protection when drilling masonry, as debris and dust are generated during operation. For best results in harder materials such as dry concrete or hard brick, use the hammer function of the drill at a controlled feed rate. Do not overheat the bit by running at excessive speed without periodic backing out to clear material.
