YG-1 TC144 HSS-E UNC spiral flute taps are bright-finish machine taps for general-purpose blind-hole threading. Their R40 spiral flute geometry supports chip evacuation during blind-hole tapping operations. A C chamfer lead helps establish the thread before full cutting engagement. This HSS-E series is rated for blind holes with depths up to 2.5×D. Spiral flute geometry also supports tapping blind and through holes where chip evacuation is required. UNC sizes span #4-40 to 1-1/8-7 for compatible machine-tapping requirements. DIN 371 applies through 3/8, with DIN 376 applied from 7/16 upward.
