OVERVIEW

Precision Threading with Walter High-Speed Steel Taps

The Walter 03B045 1/4-28NF Plug Tap is a premium-grade threading tool designed for industrial professionals who demand accuracy and durability. Crafted from top-quality High-Speed Steel (HSS), this tap is engineered to withstand the rigors of cutting threads into tough materials, including mild steel, stainless steel, and aluminum. The manufacturing process involves precision grinding of the threads, followed by a rigorous hardening and tempering treatment. This ensures that the tap maintains its cutting edge longer, reducing downtime and tool replacement costs.

As a "Plug" style tap, this tool features a chamfer of approximately 3 to 5 threads. This design makes it the most versatile choice for general threading applications. It is aggressive enough to start threads easily while still being capable of threading close to the bottom of a blind hole, provided there is some clearance. The ground threads provide exceptional precision, ensuring that the resulting internal threads meet strict tolerance requirements for secure fastening.

Whether you are manufacturing new components or performing maintenance and repair operations, the Walter 03B045 delivers consistent performance. Its free-cutting action reduces friction and heat buildup, which is critical when working with work-hardening materials like stainless steel. By choosing Walter's HSS taps, you are investing in a tool that offers a superior balance of toughness and hardness, ensuring clean, accurate threads every time.

Key Technical Benefits

The use of High-Speed Steel allows this tap to operate at higher cutting speeds compared to carbon steel alternatives without losing its temper. This efficiency is vital in high-volume production environments. Additionally, the NF (National Fine) thread profile provides greater tensile strength and finer adjustment capabilities for the final assembly.

FAQ

A plug tap typically has 3-5 chamfered threads, making it a general-purpose tap suitable for both through holes and blind holes. A taper tap has a longer chamfer (7-10 threads) to help start the thread easier but requires more depth.

This tap is made from High-Speed Steel (HSS), which offers superior durability and heat resistance compared to carbon steel taps.

Yes, the High-Speed Steel construction and precision ground threads make it suitable for cutting threads in stainless steel, as well as mild steel and aluminum.

The thread size is 1/4 inch with a pitch of 28 threads per inch (National Fine - NF).

For a 1/4"-28 NF thread, a #3 drill bit (0.2130 inches) is typically recommended for standard thread percentage.

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

No, this is the tap bit only. You will need a tap wrench or T-handle to operate it manually.

Fine threads (NF) generally have higher tensile strength and are less likely to loosen under vibration compared to coarse threads (NC).
