48-89-2803 Thunderbolt Black Oxide Drill Bit Set, Jobber Length, 15-Pc.

The Milwaukee 48-89-2803 Thunderbolt Black Oxide Drill Bit Set is a 15-piece collection of heavy-duty drill bits engineered for demanding jobsite work. These steel bits with black oxide coating are designed to drill efficiently through wood, plastics, and metals with reduced friction and minimal heat buildup. Whether you're a professional contractor or a serious DIYer, this set provides the versatility and durability needed for precision drilling across multiple materials and applications.

Black oxide coating on these Thunderbolt bits provides superior corrosion resistance and reduces heat generation during extended drilling sessions. The thicker web core design delivers ultimate strength and protects against side-load breakage that can occur when drilling on curved or uneven surfaces. The parabolic flute form clears chips and debris fast, reducing friction and requiring less effort to drill through materials.
