Description
Meet the Wiseman Threading Tools Second Lead Machine Nut Tap in M4x0.7 — a precise, durable solution for creating clean, accurate internal threads in a variety of materials. Crafted from high-speed steel (HSS) and ground to a fine finish, this tap is built for reliable performance in everyday workshop tasks without the need for coatings or special treatments.
- Second lead design (USA plug) with a two-start configuration that provides smoother chip clearance and faster thread formation, reducing tapping time on small-diameter threads.
- BS 949 dimensions ensure consistent compatibility with standardized components and fittings, making it a dependable choice for engineers and hobbyists alike.
- Right-hand thread suited for most common threading applications where the fastener turns clockwise into the workpiece.
- General-purpose, uncoated HSS delivers durable performance across a range of materials, including lightweight metals and some plastics, when used with proper cutting fluid and steady technique.
- Precision ground for accuracy and a robust flute geometry that helps maintain alignment and minimize chatter during tapping.
- Versatile use with hand or machine tap wrenches, making it ideal for repair work, prototype builds, and on-the-spot threaded inserts in metalworking and fabrication projects.
Practical guidance for best results: secure the workpiece, establish a clean pilot hole, and apply a suitable cutting fluid to reduce friction. Start with light, even pressure and rotate clockwise; pause to break chips as needed, then back off slightly to clear debris before continuing. Always verify thread engagement with the fastener and inspect for smooth, full-thread contact after tapping.
Designed for professionals and serious hobbyists who demand dependable performance from a metric HSS tap, the Wiseman Second Lead Machine Nut Tap in M4x0.7 helps you achieve strong, repeatable threads with less effort and greater control—making it a trusted addition to any tapping toolkit.
