• 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.
• Nitro-Carburized
• Manufactured to NAS 907B specification from Premium HiMolybdenum Steel.
• Magnum will substantially outperform cobalt drills in work hardening
stainless steel and other tough drilling applications.
Type 190-AG
Low temperture stress relief improves lubricity and toughness.
Type 190-CN
Nitride process case hardening resulting in superior tool life and
exceptional corrosion resistance.
