GUN TAP: UNC 5/16″ X 18 SPIRAL POINT MACH/TAP

* UNC (Unified National Course) This is a standard thread form adopted by countries like, USA, Canada and UK. * * Manufactured from quality HSS-M2 for durability and long service life * Thread Profile: Similar to Metric and is 60deg form * The crest is flat and the thread has a clearance at the root allowing internal and external to mate easily. Spiral point taps have the same general physical dimensions as standard straight flute taps. However, the spiral point tap has the cutting face of the first few threads cut at a predetermined angle relative to the tap's axis angle to force the evacuation of chips ahead of the cutting action.
