Milwaukee® Thunderbolt® Secure-Grip™ 48-89-2727 Jobber Length Drill Bit, 21/64 in Drill - Fraction, 0.3281 in Drill - Decimal Inch, 135° Point

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° 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.
