STI Tap 1/4 -20 HSS-E
The STI Tap 1/4 -20 HSS-E is a versatile tool designed to create threads in nonferrous metals with ease and precision. Its high-speed steel composition ensures long-lasting durability, producing smooth cutting threads that minimize breakage during use. Ideal for hobbyists or professionals working on automotive, aviation, electronics, or machining projects, this tap's square neck fits dies accurately, allowing users to achieve precise results without additional tools. In industries where threading is essential for assembling and disassembling components securely and efficiently, the STI Tap 1/4 -20 HSS-E is an indispensable asset that delivers reliable performance at a competitive price point.
The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating. Cobalt taps are harder and provide more wear resistance when tapping hard materials at high speeds than high-speed steel taps.
