Precision. Strength. Durability.

The Milwaukee® THUNDERBOLT® 21-Piece Black Oxide Drill Bit Set is engineered for heavy-duty jobsite performance. Featuring a Black Oxide coating, these bits reduce heat build-up, prevent corrosion, and ensure long-lasting durability.

With a thicker core, Milwaukee THUNDERBOLT® bits provide ultimate strength and protect against side-load breakage, while the specially designed parabolic flute form clears chips and debris quickly, keeping the bit cool for faster, more efficient drilling.

The 135° split point tip ensures precise starts and prevents walking, allowing for fast, accurate holes in wood, plastics, and metals. This 21-piece set comes in a customizable accessory case, compatible with Milwaukee’s PACKOUT™ modular storage system for maximum organization and portability.
