Dewalt Accessories DW1121 Black Oxide Drill Bit 21/64 in 2pk

Product Description

The DEWALT ACCESSORIES DW1121 is a 21/64 inch black oxide drill bit sold in a 2-pack for trade professionals and experienced DIYers. Manufactured from high-speed steel with a black oxide finish, the DW1121 delivers greater wear resistance and extended service life across repeated use. The 135-degree split point tip engages material on contact and eliminates walking, reducing the need for a center punch on most surfaces. A patented core diameter and tapered web design reduce the risk of bit breakage during demanding drilling applications.

The DW1121 is suited for drilling into plastic, wood, and metal in general construction, mechanical, and finish work. The no-spin shank design keeps the bit secure in the chuck under load, and clear size markings allow fast identification on the job. This bit is appropriate for residential and light commercial work where a reliable general-purpose twist bit is required.
