3/8" Cryo-Tech Drill Bit

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 stainless steel, iron, steel, and other hard metal drilling applications.

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
