29 pc Cryo-Tech Drill Bit Set w/ Plastic Container

Nitride process case hardening resulting in superior tool life and exceptional corrosion resistance. Cryogenic treatment at -300° F increases toughness while reducing brittleness. Recommended for use on stainless steel, iron, and steel.

Features:

• Modifies the carbon micro-structure through precipitation of carbides increasing resistance to wear.
• Nitride process diffuses nitrogen into the surface to create a case hardening resulting in superior tool life and exceptional corrosion resistance.
• Cryogenic treatment creates a more uniform "grain" structure by transforming retained austenite into martensit
