Description

The 13MM Cobalt RED HELIX™ Twist Drill Bit is designed for exceptional strength and high-performance drilling in tough metals. Its variable helix design, transitioning from a steep 35° angle to a 15° taper, promotes fast chip evacuation, reduces heat buildup, and preserves cutting sharpness.

Equipped with a 135° QUAD EDGE™ split-point tip, this drill bit ensures precise, walk-free starts for fast and accurate hole placement. The four-edge cutting geometry produces finer chips for smoother drilling, enhanced heat dissipation, and extended tool life.

An optimized internal taper web strengthens the bit, minimizing the risk of breakage during heavy-duty use. Finished with a premium cobalt coating, it offers up to 10 times the lifespan of standard black oxide bits, making it a reliable solution for demanding drilling projects.
