Super Primalloy® Cryo-Gen N™ Maintenance Length Drill Bits
Enhanced by a multi‑phase cryogenic treatment down to ‑300 °F, these bits refine grain structure for less brittleness. The “N” series nitride hardening boosts edge retention, and a 135° split point eliminates the need for center punching. Maintenance length adds rigidity in tight spaces. Ideal for high‑tensile steels, they’re built with tough M series alloy.
