PRODUCT OVERVIEW
Milwaukee
Thunderbolt® black oxide jobber length drill bits are designed for extreme
durability and long life. The Thunderbolt® web features a thicker core than a
standard drill bit to provide ultimate strength and protect against side-load
breakage. A specially designed parabolic flute form clears chips fast, while
the 3-flat Secure-Grip shank holds the bit firmly in the drill chuck. The 135
deg split point tip delivers a precision start and prevents walking for fast,
accurate holes. Effective for drilling on curved surfaces, Milwaukee
Thunderbolt® black oxide bits require less effort to drill through metal, wood
and PVC and are highly recommended for use with portable drills.
