Walter 1/2-20 NF HSS Plug Tap for Steel and Stainless

Reliable Taps for the Toughest Shop Jobs

When you are in the middle of a fabrication job or fixing a stripped thread on a piece of heavy equipment, the last thing you need is a tap that snaps off in the hole. The Walter 1/2-20 NF Plug Tap is built for welders and fabricators who need tools that work as hard as they do. Made from heavy-duty High-Speed Steel (HSS), this tap cuts through metal with ease, leaving you with clean, precise threads that hold tight.

This isn't your average hardware store tap. Walter has designed this tool with ground threads that are hardened and tempered to resist dulling. If you work with stainless steel, you know how tough it can be on cutting tools. This HSS tap is up to the challenge, slicing through stainless, mild steel, and aluminum without overheating or binding up. The precision grinding means less friction, which translates to less force needed on the tap wrench and a lower chance of breakage.

The "Plug" style design is the workhorse of the tapping world. With a tapered starting edge of 3-5 threads, it aligns easily in the hole to get you started straight, but still cuts threads deep enough for most applications. It is perfect for through-holes where the chips can fall out the bottom, and it works great for general thread repair. Whether you are tapping a new hole in a mounting plate or chasing damaged threads on a bolt hole, this 1/2-20 Fine Thread tap is an essential addition to your tool chest.

Don't settle for cheap carbon steel taps that dull after one use. Upgrade to Walter's industrial-grade HSS taps and experience the difference in cut quality and tool life. Remember to use a good quality cutting fluid or tapping paste to extend the life of the tool even further and ensure the smoothest possible thread finish.
