OVERVIEW

Precision Threading with Walter High-Speed Steel Taps

The Walter 10-32 NF Plug HS Tap (03A105) is a professional-grade threading tool designed to deliver superior performance in industrial environments. Crafted from top-tier High-Speed Steel (HSS), this tap is engineered to withstand the high temperatures and stresses associated with cutting threads in tough materials like stainless steel and mild steel. Unlike standard carbon steel taps, Walter's HSS composition ensures the cutting edges remain sharp for longer, reducing the frequency of tool replacements and ensuring consistent thread quality over the lifespan of the tool.

This specific model features a Plug chamfer, which is the most versatile style for general threading operations. With a chamfer length of approximately 3 to 5 threads, it is perfectly suited for through holes where the chips can be pushed forward, or for blind holes where threading to the very bottom is not critical. The "NF" designation indicates a National Fine thread pitch (32 threads per inch), which provides greater tensile strength and finer adjustment capabilities compared to coarse threads, making it an excellent choice for precision assemblies and high-vibration applications.

Walter Surface Technologies has hardened and tempered these taps to exacting standards. This thermal treatment enhances the tool's toughness, preventing the brittleness that often leads to snapped taps in deep holes. The threads are precision ground rather than cut, ensuring tight tolerances and a smooth finish on the final workpiece. Whether you are repairing stripped threads in an engine block or fabricating new components from aluminum stock, the Walter 10-32 NF Plug Tap offers the reliability and effortless cutting action required by maintenance professionals and machinists alike.

Key Applications

  • Maintenance & Repair: Ideal for re-threading damaged holes in machinery and equipment.
  • Fabrication: Creating new internal threads in mild steel, stainless steel, and non-ferrous metals.
  • Assembly: Perfect for applications requiring fine thread adjustments and high holding power.

FAQ

A Plug tap typically has 3-5 chamfered threads, making it suitable for through holes or general use. A Taper tap has a longer chamfer (7-10 threads) for easier starting, while a Bottoming tap has very little chamfer (1-2 threads) for threading to the bottom of blind holes.

For a standard 10-32 NF thread, a #21 drill bit is typically recommended to achieve approximately 75% thread percentage.

Yes, this tap is made from High-Speed Steel (HSS) and is hardened and tempered specifically to handle tough materials like stainless steel, as well as mild steel and aluminum.

NF stands for 'National Fine'. It refers to the thread pitch series. Fine threads generally have higher tensile strength and are less likely to loosen from vibration compared to Coarse (NC) threads.

While HSS taps can be used in machine setups, care must be taken with hand drills to ensure perfect alignment to avoid breaking the tap. It is often safer to use a drill press or tap wrench for manual tapping.

Ground threads are manufactured to tighter tolerances and have a smoother surface finish. This reduces friction during the tapping process and results in a more accurate thread form.
