Thread Forming Tap: #1-72 UNF, 2BX Class of Fit, Modified Bottoming, Cobalt, Nitride Coated MPN:BU921000.5034

This precision thread forming tap is made from Cobalt High Speed Steel material which provides outstanding strength, wear resistance, and hardness. The tap's overall length of 2 inches makes it ideal for use in deep holes or narrow spaces while its 1-72 UNF standard threads can easily create screw thread forms that require the lowest minimum hole depth. Featuring a 60 standard point and 3% rule rule thread diameter variation ensures excellent centering capability on both metric and inch size materials, eliminating the need for pilot holes or special tap adapters. The Modified bottoming style has a distinct profile that ensures positive thread start-up with maximum holding power even in poorly fitted hole conditions and can be used to cut left-hand threads from either direction making it applicable in a wide range of manufacturing, automotive, machining or hobby applications.
