81073 Type 150-ALN Jobber Length TiAIN NAS 907J 135Â degree Split Point Drill Bit (6 pack) 0.688" ID structure by transforming retained austeniteManufactured from M42 HSS containing 8% cobalt which increases high red hardness. Cobalt drills require rigidly held positive feed drilling equipment. Titanium Aluminum Nitride can be used in machining stainless steel, nickel based and titanium alloys, not recommended for aluminum. Manufactured to NAS 907J specifications. Titanium aluminum nitride designed for use where extreme temperatures are found, allows for increased machining speeds up to 200%.
