Greenfield Threading's Spiral Point Tap is an ideal solution for anyone looking to achieve precise, accurate threading in their machining projects. Designed with UNC threads that perform better in brittle material applications, this tap offers superior performance compared to UNF taps and is less likely to cross thread. Its coarse threads are also stronger than fine threads and can withstand more physical abuse. With a bright finish that provides a smooth, polished surface, you can trust Greenfield Threading's Spiral Point Tap to deliver precision threading time after time. The 1/4-20 thread size makes it suitable for a wide range of applications and its High Speed Steel construction ensures durability and long-lasting performance.
