Norseman Drill Bit CN TECH Split Point HSS Jobber Length Cryogenic Drill Bits USA Made - 2 Pack (3/16 )

Superior to Cobalt bits cryogenic treatment drill bits are the latest cutting edge technology! Cryogenic treatment creates a more uniform grain structure by transforming retained austenite into martensite. Modified carbon micro-structure through precipitation of carbides makes these bits extremely sharp and resistant to wear. Norseman CN-Tech Drill Bits are cryogenically frozen to -300 degrees fahrenheit for hours which reduces the brittleness of the drill bits increasing strength and decreasing the chance of the bit shearing.
