Dw1128 Black Oxide Drill Bit, 135° Split Point, 7/16 In.

The DeWalt DW1128 7/16-inch black oxide drill bit delivers fast, accurate hole drilling in wood, metal, fiberglass, PVC, and stainless steel. The precision-engineered 135° split-point tip starts drilling on first contact, eliminating the need for a center punch and preventing the bit from walking across the work surface. This makes hole placement cleaner and more professional, whether you're working on metalworking projects, construction tasks, or general shop work.

The patented core-diameter geometry reinforces the shank to reduce flex and prevent breakage during high-torque drilling applications. The black oxide coating provides superior wear and corrosion resistance, extending tool life and maintaining consistent performance even after repeated use in demanding environments. These features combine to reduce project downtime from bit failures and deliver reliable, repeatable results across a wide range of materials.
