IRWIN 29-Piece Black Oxide Metal Drill Bit Set with Case

Upgrade your toolbox with the IRWIN 29-Piece Black Oxide Metal Index Drill Bit Set. Designed for efficiency and durability, these bits feature a specialized oxide treatment that resists corrosion and helps prevent rust during use. Whether you are working on professional projects or DIY tasks, the 135 degree split-point tip ensures each bit starts on contact, allowing you to cut through metal with less force and better control. This versatile set is built for convenience. Larger bits feature a reduced shank above 3/8 inch, making them compatible with 3/8-inch chucks for added flexibility in your workshop. To keep your tools organized and safe, the set comes in a durable, rubber over-molded case that provides protection against accidental drops. For quick guidance during your projects, the kit also includes a Tap and Drill selection chart, making it easy to find the right size every time you work.
