Black & Gold 21/64 In. X 4-11/16 In. L High Speed Steel Drill Bit 3-Flat Shank 1 Pk

The DeWalt DW1121 is a precision black oxide drill bit designed for fast, accurate drilling in metal, stainless steel, aluminum, and other tough materials. The 135° split-point tip initiates contact instantly on the first rotation, eliminating wobble and ensuring clean, precise holes without walking or wandering on the workpiece. This jobber-length bit is ideal for assembly work, fabrication, maintenance, and any application requiring reliable medium-sized holes in metal and conductive materials.

Black oxide coating delivers superior hardness and exceptional wear resistance, extending tool life and reducing the need for frequent bit changes. The patented core diameter design provides extra rigidity and lowers the risk of breakage under high torque, giving you confidence in tight-tolerance projects. A tapered web eliminates the frustration of bit spinning in the chuck, keeping your drilling smooth and efficient.
