Each bit in the 15-piece Milwaukee Tool Thunderbolt Black Oxide Drill Bit Set is all jobber length bits designed and built for durability and long service life. The bit's tapered Thunderbolt web has a thicker core than a standard drill bit, providing ultimate strength and protection against sideloading breakage.

The parabolic flute form is specially designed to clear chips and debris fast and keep the bit cool. A 135° split point tip ensures a precision start and prevents walking for fast, accurate drilling. Milwaukee Thunderbolt Black Oxide bits are great for drilling on curved surfaces and require less effort to drill through metal, wood, and PVC, and are ideal for portable drills.
