OVERVIEW

Precision Threading with Walter HSS Plug Taps

The Walter 03B105 5/8-18 NF Plug HS Tap is a premium-grade threading tool designed for industrial professionals who demand accuracy and longevity. Manufactured from high-quality High Speed Steel (HSS), this tap is engineered to cut precise threads into a variety of tough materials, including mild steel, stainless steel, and aluminum. The HSS construction ensures that the cutting edges remain sharp even under high thermal stress, significantly outperforming standard carbon steel taps in production environments.

This specific model features a "Plug" chamfer, typically consisting of 3 to 5 threads. This design makes it the most versatile style of tap, suitable for the majority of through-hole applications and blind holes where threading to the very bottom is not critical. The precision-ground threads reduce friction during the cutting process, allowing for lower torque requirements and a cleaner finish on the internal threads of your workpiece. Whether used in a manual tap wrench or a machine setup, the Walter 03B105 delivers consistent performance.

Durability is a hallmark of Walter Surface Technologies' tooling. The 03B105 undergoes a rigorous hardening and tempering process, balancing hardness for cutting power with the toughness required to resist chipping. This makes it an excellent choice for maintenance, repair, and operations (MRO) as well as fabrication shops dealing with diverse metal grades. By choosing this National Fine (NF) thread tap, you ensure a tighter, stronger thread engagement for assemblies requiring high vibration resistance.

Incorporating this tool into your workflow means fewer tool changes and more reliable threading operations. It is compatible with standard tapping fluids and lubricants, which are recommended to further extend tool life and improve thread quality. Trust Walter's engineering to provide the bite and resilience needed for your most critical fastening projects.

FAQ

For a 5/8-18 NF thread, the standard recommended drill bit size is 37/64 inches. This provides the optimal percentage of thread engagement for a strong connection without putting excessive stress on the tap.

Yes, the Walter 03B105 is made from High Speed Steel (HSS), which is durable enough to tap stainless steel effectively. Using a high-quality cutting lubricant is highly recommended when tapping stainless to prevent work hardening and extend tap life.

A plug tap, like this one, has a chamfer of 3-5 threads, making it suitable for through holes or blind holes with some clearance. 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.

Yes, Walter HSS taps are precision ground and suitable for use in both manual tap wrenches and machine tapping heads, provided the correct speed and lubrication are used.

While it is possible to tap soft materials dry, using a cutting fluid or tapping paste is strongly recommended for all metals. It reduces friction, clears chips, and keeps the tool cool, significantly extending the life of the tap and improving thread quality.

NF stands for 'National Fine'. It indicates that the thread pitch (18 threads per inch) is finer than the standard coarse thread (NC) for this diameter. Fine threads are often used for greater strength and finer adjustment.

Yes, this tap is excellent for 'chasing' or cleaning up damaged threads in existing holes, as long as the original hole was tapped to 5/8-18 NF.

High Speed Steel (HSS) is much harder and more heat-resistant than carbon steel. It stays sharp longer and can cut through tougher materials like stainless steel without dulling immediately, making it a better investment for professional use.
