Milwaukee 48-89-2722 Jobber Drill Bit, 1/4 in Dia, 4 in OAL, Parabolic Flute, 3-Flute, 1/4 in Dia Shank

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. For drilling on curved surfaces Features: - Thicker web provides greater strength and longer life - Black oxide coating provides lubricity and resists corrosion of the bit - 135 deg split-point tip starts on contact to prevent walking, while the parabolic flute clears chips fast - 3-flat Secure-Grip shank holds the bit firmly in the drill chuck
