The RED HELIX™ Cobalt Drill Bits are engineered for extreme durability and longer life in hard metal applications. The drill bits now feature a QUAD EDGE™ Tip designed with four cutting edges that help decrease heat buildup and drill faster. The tapered drill bits’ new Enhanced Tapered Web strengthens the bits’ cores to increase flute durability. The bits also use a Variable Helix flute that includes an aggressive 35° Helix Angle which ends at 15°. The 135° Split Point Tip delivers a precision start and prevents walking for fast, accurate holes in Wood, PVC, mild steel, and stainless steel.
