| Editorial Reviews:
Product Description Precision Twist Drill Metric Cobalt Drill Bits have a self-centering 135 Degree split point that penetrates faster than other point styles, produces smaller chips for better chip flow, and won't walk or skid when starting a hole.Their nitro-carburized surface treatment improves lubricity and wear resistance. Cobalt steel drill bits have better heat and abrasion resistance for drilling high tensile-strength materials and materials that get harder during machining.
