The DeWalt DW5229 is a percussion masonry drill bit designed for drilling in concrete, brick, stone, and rock. This 5/16-inch by 12-inch bit is essential when you need to install anchors, set fixtures, or create holes in tough masonry materials. The rock carbide tip maximizes surface contact with hard materials, extending bit life and delivering reliable drilling results.
The flat shank with three flats prevents bit slippage in the chuck, ensuring stable drilling and improved accuracy. The specialized 4-flute design efficiently removes dust and debris while you work, reducing binding and keeping the bit running smoothly. This combination of features makes the DW5229 a dependable choice for demanding masonry drilling applications.
Features and Benefits
- Rock Carbide Tip: Maximizes surface contact with concrete, masonry, and stone, extending bit life up to two times longer than standard tips.
