Milwaukee 48-89-2727 21/64" Thunderbolt Black Oxide Drill Bit (5 Pack)

5 Drill Bits

Milwaukee Thunderbolt Black Oxide jobber length drill bits are built for extreme durability and long life. The Thunderbolt web has a thicker core than a standard drill bit for ultimate strength and protection against side-load breakage. A specially designed parabolic flute form clears chips fast, and the 3-Flat Secure-Grip shank holds the bit firmly in the drill chuck. The 135° split point tip gives a precision start and prevents walking for fast, accurate holes. Effective on curved surfaces, Milwaukee Thunderbolt Black Oxide bits take less effort to drill through metal, wood and PVC and are highly recommended for portable drills.
