Viking Norseman Cryo-Tech Drill Bit, 5/16"

Viking Norseman Cryo-Tech Drill Bit, 5/16"

The 5/16" Norseman Cryogenic Drill Bit is a premium fractional-size jobber length drill bit engineered for precision, durability, and extended tool life. Part of Norseman’s Type 190-CN CN-Tech series, this bit undergoes a deep cryogenic treatment process, freezing the steel to -300°F for 48 hours to enhance hardness, strength, and wear resistance. Precision-ground cutting geometry combined with a 135° split point allows for accurate starts and efficient cutting, while three flats on the shank reduce slipping in drill chucks. Made in the U.S.A., these bits represent cutting-edge drilling performance—because a drill bit that lasts longer means fewer interruptions and cleaner holes.
