OVERVIEW

Precision Threading with Walter High Speed Steel Taps

The Walter 03B072 7/16-14 NC Plug Tap is a premium cutting tool designed for industrial professionals who demand accuracy and longevity. Manufactured from the finest High Speed Steel (HSS), this tap is engineered to withstand the high thermal and mechanical stresses associated with threading hard metals. Unlike standard carbon steel taps that dull quickly, Walter's HSS composition ensures the cutting edges remain sharp even after repeated use in demanding materials such as stainless steel and aluminum.

One of the defining features of this product is its precision-ground threads. The grinding process guarantees tight tolerances and a smooth surface finish on the threads it cuts, reducing the likelihood of binding or cross-threading. The tap undergoes a rigorous hardening and tempering process, which balances hardness for cutting power with toughness to resist chipping under torque. This makes it an exceptional choice for maintenance, repair, and operations (MRO) environments where reliability is paramount.

As a "Plug" style tap, this tool features a chamfer of approximately 3 to 5 threads. This design strikes a perfect balance between starting the thread easily and cutting full threads relatively close to the bottom of a hole. It is the most commonly used style for through holes, where the chips can be pushed forward, but it is also effective for blind holes if there is sufficient clearance at the bottom. Whether you are fabricating new components or repairing damaged threads in existing machinery, the Walter 03B072 delivers consistent, high-quality results.

Operators will appreciate the reduced friction provided by the high-quality finish of the tool, which translates to lower torque requirements and less heat generation. This efficiency not only speeds up the workflow but also protects the workpiece from heat-related distortion. Compatible with standard tap handles and machine holders, this tap integrates seamlessly into any professional toolset.

FAQ

A plug tap has a chamfer of 3-5 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 a blind hole.

The recommended drill bit size for a 7/16-14 NC tap is typically a Letter U drill bit (0.3680 inches) or a 9.35mm bit to achieve approximately 75% thread height.

Yes, this Walter tap is made from High Speed Steel (HSS), which is durable enough to cut threads in stainless steel, as well as mild steel and aluminum.

This is a 7/16-14 NC tap, which stands for National Coarse. It cuts coarse threads (14 threads per inch).

Yes, using a high-quality cutting fluid or tapping oil is highly recommended. It reduces friction, dissipates heat, and extends the life of the tap while ensuring a cleaner thread finish.

HSS stands for High Speed Steel. It is a tool steel alloy that can withstand higher temperatures without losing its temper (hardness), allowing it to cut faster and last longer than carbon steel tools.

While it is possible to use taps with power tools that have a specific tapping mode or clutch, this hand tap is primarily designed for use with a tap wrench or a tapping head to ensure alignment and prevent breakage.

A plug tap can be used for blind holes if there is enough clearance at the bottom for the 3-5 thread chamfer. For threading all the way to the bottom of a blind hole, a bottoming tap would be required after starting with the plug tap.
