The Milwaukee 1/2 inch Thunderbolt™ Black Oxide Jobber Length Drill Bit is built for reliable performance and extended life in general-purpose drilling applications. Designed for use in metal, wood, and PVC, this bit features a thick core construction to reduce breakage and a parabolic flute design that rapidly clears chips for cooler, more efficient drilling.
Its black oxide coating provides added lubrication and corrosion resistance, helping maintain cutting efficiency over time. The 135° split-point tip delivers accurate starts without walking, while the 3-Flat Secure-Grip™ shank keeps the bit firmly locked in the chuck for stable operation in portable drills and drivers.
