Milwaukee Thunderbolt 48-89-2821 drill bits are built for durability and long life. The thicker web design enhances strength and reduces side-load breakage. Features a parabolic flute for effective chip removal and a 135-degree split point tip for precision drilling. Excellent for use on curved surfaces, these bits require less effort to drill and are ideal for portable drills. The secure-grip shank minimizes slippage.
Designed for drilling through metal, wood, and plastic. The black oxide finish offers corrosion resistance and lubricity.
