3/4-10 NC High-Speed Steel Plug Tap

Heavy-Duty Thread Repair and Fabrication

For welders and metalworkers, a stripped thread or a new bolt hole shouldn't bring a project to a halt. The Walter 3/4-10NC Plug Tap is built to handle the gritty reality of the welding shop. Made from robust High-Speed Steel, this tap is designed to cut through stubborn metals like stainless steel and mild steel without losing its edge. Unlike cheaper carbon steel taps that dull quickly, the Walter 03B122 stays sharp, ensuring you can clean up damaged threads or cut new ones with confidence.

This plug tap features a standard chamfer that allows for easy starting in the hole while still being aggressive enough to cut full threads relatively quickly. It is the go-to style for most general-purpose threading jobs, especially for through holes on brackets, plates, and machinery frames. The precision ground flutes help clear chips effectively, preventing binding that can lead to snapped taps—a headache every fabricator wants to avoid.

Whether you are fabricating a custom heavy-duty mount or repairing threads on a piece of agricultural equipment, this tool provides the bite you need. Pair it with a high-quality cutting fluid like Walter Coolcut to maximize performance and ensure the smoothest possible thread finish. Add this durable tap to your toolbox and ensure your connections are secure and professional every time.
