The 13/32 Inch Cobalt RED HELIX Twist Drill Bit is built for exceptional strength and high-performance drilling in tough metal applications. Its advanced Variable Helix design, transitioning from a bold 35° angle to 15°, promotes faster chip evacuation, reduces heat buildup, and helps maintain a sharp cutting edge. The QUAD EDGE 135° split point tip enables accurate, walk-free starts for clean and precise holes. With four cutting edges producing smaller chips, this drill bit delivers smoother operation, improved efficiency, and extended service life. A reinforced internal taper web enhances overall durability, minimizing the risk of breakage under demanding conditions. Finished with a premium cobalt coating, it offers up to 10 times longer life compared to standard black oxide bits, making it a reliable choice for heavy-duty twist drilling tasks.
