Dewalt Accessories DW1177 Black Oxide Drill Bit Set 20pc

Product Description

The DEWALT ACCESSORIES DW1177 is a 20-piece black oxide drill bit set engineered for drilling in metal, wood, and plastics. Each bit features a black oxide finish that improves wear resistance and extends service life. The parabolic flute design increases bit strength and clears chips efficiently during drilling. A 135-degree split point tip reduces walking and allows for accurate, no-slip starts without center punching. The set ships in a sturdy case with a sliding soft-grip lock to keep bits organized and secure on the job site. Installers, tradespeople, and experienced DIYers will find this set suited to high-frequency, multi-material drilling tasks.

This set is appropriate for residential and light commercial applications where drilling in steel, sheet metal, wood framing, and plastic components is routine. The wide size range makes it practical for electricians, plumbers, HVAC technicians, and general contractors who need a single organized kit covering common hole sizes from small pilot work up to half-inch bores. The included case keeps sizes sorted and accessible during service calls or on the bench.

Installation Notes

Select the correct bit size for the application and secure it firmly in the drill chuck before use. Always wear appropriate eye protection when drilling metal or hard plastics. Reduce feed pressure on thinner materials to avoid breakthrough tear-out, and use cutting fluid when drilling ferrous metals to extend bit life. Return bits to the labeled case slots after use to maintain set organization.
