OVERVIEW

Precision Threading with Walter High Speed Steel Plug Taps

The Walter 03B102 5/8"-11 NC Plug Tap is a premium threading tool designed for industrial professionals who demand accuracy and longevity. Manufactured from top-quality High Speed Steel (HSS), this tap is engineered to withstand the thermal and mechanical stresses associated with cutting threads in hard metals. Unlike carbon steel alternatives, Walter's HSS composition ensures the cutting edges remain sharp longer, reducing the frequency of tool changes and ensuring consistent thread quality across multiple operations.

This specific model features a "Plug" chamfer style, characterized by a 3-5 thread tapered lead. This design makes it the ideal choice for threading through holes, where the chips can be pushed forward out of the hole. The precision-ground threads minimize friction, allowing for smoother cutting action and reducing the torque required to drive the tap. Whether you are manufacturing new components or repairing damaged threads in maintenance applications, the dimensional accuracy of this tap ensures a tight, compliant fit for fasteners every time.

Versatility is a key strength of the Walter 03B102. It is hardened and tempered to perform exceptionally well across a variety of materials, including mild steel, stainless steel, and aluminum. The 5/8"-11 UNC (Unified National Coarse) configuration is a standard size for heavy-duty fastening, making this tool an essential addition to any machine shop or maintenance crib. By choosing Walter, you are investing in a tool that balances toughness with precision, ensuring your threading operations are efficient and reliable.

FAQ

A plug tap typically has a chamfer of 3-5 threads, making it suitable for through holes. 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 blind holes.

The standard tap drill size for a 5/8"-11 NC thread is 17/32 inch (or approximately 13.5mm) for a 75% thread engagement.

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

While it can be used, a plug tap is best for through holes. For a blind hole, you would typically start with a plug tap and finish with a bottoming tap to thread all the way to the bottom.

NC stands for National Coarse, which refers to the thread pitch. 5/8"-11 means the diameter is 5/8 inch and there are 11 threads per inch.

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

It is made of High Speed Steel (HSS), which offers superior heat resistance and durability compared to carbon steel taps.

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