OVERVIEW

Precision Threading with Walter High-Speed Steel Taps

The Walter 03B092 9/16-12 NC Plug Tap is an industrial-grade threading tool designed for professionals who demand accuracy and longevity. 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 metals. Unlike standard carbon steel taps that can dull quickly or chip under pressure, Walter's HSS composition ensures the cutting edges remain sharp even after repeated use in demanding applications.

One of the standout features of this product is its precision ground threads. The grinding process creates a much smoother and more accurate thread profile compared to cut threads, resulting in lower friction during operation and a superior finish on the workpiece. This tap has been hardened and tempered to achieve the optimal balance between hardness for cutting and toughness to resist breakage. Whether you are manufacturing new components or repairing damaged threads in maintenance operations, this tool delivers consistent performance.

The "Plug" style chamfer features a 3-5 thread taper at the tip. This makes it the most versatile choice for general-purpose threading, suitable for both through holes and blind holes (provided the threads do not need to go all the way to the bottom). It is specifically designed to handle a wide range of materials, including aluminum, mild steel, and stainless steel, making it a versatile addition to any machine shop or maintenance department.

Key Technical Benefits

  • Superior Material: High-Speed Steel substrate resists heat buildup and edge wear.
  • Accuracy: Ground threads ensure Class 2B fit tolerances are easily met.
  • Versatility: Effective on ferrous and non-ferrous metals.
  • Durability: Hardened structure prevents tooth chipping during start-up.

FAQ

For a standard 9/16"-12 UNC thread, the recommended tap drill size is typically 31/64".

A plug tap has a chamfer of 3-5 threads, making it general-purpose. A taper tap has a longer chamfer (7-10 threads) for easier starting, while a bottoming tap has almost no chamfer (1-2 threads) for threading to the bottom of a hole.

Yes, because it is made of High-Speed Steel (HSS), it is capable of cutting threads in stainless steel, as well as mild steel and aluminum.

This tap can be used by hand with a tap wrench or in a machine tool holder, depending on the application.

NC stands for National Coarse, which is synonymous with UNC (Unified National Coarse). It indicates the standard coarse thread pitch.

Yes, using a high-quality cutting fluid or tapping compound is highly recommended to reduce friction, clear chips, and extend the life of the tap.

The Walter 03B092 is made from High-Speed Steel (HSS), which offers superior hardness and heat resistance compared to carbon steel.

Yes, a plug tap can be used for blind holes, but it will not create full threads all the way to the very bottom. For that, a bottoming tap is required after using the plug tap.
