The Milwaukee Red Helix 29-Piece Cobalt Drill Bit Set is engineered for extreme durability and long life in hard metal applications. These drill bits are designed with a Variable Helix that includes an aggressive 35-degree Helix Angle which ends at 15 degrees. The drill bits have Quadedge Tip to decrease heat buildup and drill faster. The 135-degree split point tip delivers a precision start and prevents walking for fast, accurate holes in Hard Metal, PVC, and wood. The tapered drill bits feature a new Enhanced Tapered Web that strengthens the bit's core to increase flute durability. The cobalt twist drill bits are ideal for tough applications, providing up to 15x life vs. Black Oxide Drill Bits.
