Milwaukee RED HELIX™ 3/8" Reduced 3-Flat Shank 1/2" Cobalt Drill Bit is engineered for extreme durability and long-lasting performance.

This drill bit is equipped with a 135° SPLIT POINT TIP™ that ensures precise starting and prevents walking, while the 3-Flat Secure-Grip™ shank keeps the bit securely fixed in the chuck. Additionally, the QUADEDGE TIP™ helps prevent heat build-up, extending the bit’s life and maintaining cutting efficiency. Model Number: 48-89-2329
