Milwaukee 5/16 in. 6449631 Jobber Drill Bit

The Milwaukee 5/16 in. 6449631 Jobber Drill Bit is designed for extreme durability and long service life. Built with a Thunderbolt web featuring a thicker core than standard drill bits, it provides ultimate strength and helps protect against side-load breakage during heavy-duty applications. The black oxide coating offers lubricity and resists corrosion for dependable performance. Featuring a specially engineered parabolic flute form, this drill bit clears chips rapidly to maintain drilling efficiency. The split point tip delivers a precision start on contact to prevent bit walking, making it effective for drilling on flat and curved surfaces across metal, wood, and PVC materials. A 3-flat Secure-Grip shank holds the bit firmly in portable drill chucks to eliminate slippage.
