Walter 12-24 NC High-Speed Steel Plug Tap

Reliable Threading for the Fabrication Shop

Every welder knows the frustration of a cheap tap snapping off inside a finished part. The Walter 12-24 NC Plug HSS Tap is built to prevent that headache. Designed for the rigors of the metal fabrication shop, this tap is crafted from high-quality High-Speed Steel (HSS), giving it the backbone needed to cut through tough materials like stainless steel and heavy structural plate without losing its edge. When you are finishing a custom bracket or repairing a mounting hole on a piece of equipment, you need a tool that bites into the metal and cuts a clean thread on the first pass.

This tap features a Plug style chamfer, which is the most versatile configuration for general shop use. With a tapered start of 3 to 5 threads, it aligns easily into the hole and starts cutting immediately, making it ideal for through-holes where the chips can be pushed out the other side. The 12-24 NC (National Coarse) thread size is a common specification in industrial machinery and electrical enclosures, making this a must-have item in your tool chest.

Walter Surface Technologies is known for producing abrasives and tools that last, and this tap is no exception. The precision-ground threads ensure that bolts and screws thread in smoothly, which is critical when assembling parts that may need to be disassembled later for maintenance. Whether you are working on aluminum fixtures, mild steel frames, or stainless food-grade equipment, this tap handles the job with consistency.

Don't settle for carbon steel taps that dull after a few holes. Upgrade to HSS for a longer service life and better performance. Whether you are tapping by hand with a T-handle or using a drill press at low RPM, the Walter 03A122 provides the reliability professional fabricators demand. Keep your projects moving and your threads clean with this industrial-grade solution.
