Norseman CN-Tech Cryogenic Frozen Drill Bits: Priced Individually
Made in the USA!
135° Split Point Type 190-CN.
Cryogenic treatment creates a more uniform “grain” structure by transforming retained austenite into martensite.
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.
