Milwaukee® 48-89-2733 Thunderbolt® Secure-Grip™ Jobber Drill, 27/64 in Dia x 5-3/8 in L, HSS, Black Oxide

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.
