OVERVIEW

Precision Threading with High Speed Steel

The Walter 6-32 NC Taper Tap (SKU: 03A061) represents the pinnacle of threading tool engineering, designed for industrial professionals who demand accuracy and longevity. Manufactured from premium High Speed Steel (HSS), this tap is engineered to withstand the high thermal stresses and abrasive forces encountered during metalworking. Unlike standard carbon steel taps, HSS maintains its hardness at higher temperatures, ensuring that the cutting edges remain sharp even after prolonged use in tough materials like stainless steel.

The defining feature of this tool is its precision-ground threads. Walter utilizes advanced grinding technology to ensure that every flute and thread profile meets strict tolerance standards. This results in a tap that cuts freely with reduced friction, producing threads that are dimensionally accurate and smooth. The "Taper" chamfer style features a gradual lead-in of 7 to 10 threads. This geometry distributes the cutting load over a larger number of teeth, making it the ideal choice for starting new threads in a hole. It significantly reduces the torque required to initiate the cut and helps align the tap perpendicular to the workpiece, minimizing the risk of breakage or cross-threading.

This tool is versatile enough for a wide range of maintenance, repair, and operations (MRO) applications. Whether you are tapping through-holes in structural steel or repairing damaged threads in an aluminum casting, the Walter 03A061 delivers consistent performance. It is hardened and tempered to provide the optimal balance between hardness for cutting and toughness to resist chipping.

Technical Specifications

The 6-32 NC configuration adheres to National Coarse standards, making it compatible with standard fasteners found across North American machinery and equipment. For optimal results, it is recommended to use this tap with a high-quality cutting fluid, such as Walter Coolcut, to further reduce friction and evacuate chips efficiently.

FAQ

A taper tap has a longer chamfer (7-10 threads) which helps in starting the thread straight and distributes cutting force. A plug tap has a shorter chamfer (3-5 threads) and is used after the thread is started or for holes that don't go all the way through.

For a 6-32 NC thread, the standard drill bit size is a #36 drill bit.

Yes, because it is made of High Speed Steel (HSS), it is capable of cutting threads in stainless steel, unlike carbon steel taps.

Yes, using a tapping fluid or cutting oil is highly recommended to reduce friction, prevent overheating, and extend the life of the tap.

Taper taps can be used in blind holes to start the thread, but they will not thread all the way to the bottom. You would typically follow up with a bottoming tap to finish a blind hole.

NC stands for 'National Coarse', which refers to the standard thread pitch for this size fastener.

The gradual taper acts as a guide, making it much easier to keep the tap perpendicular to the workpiece when turning it by hand.

This is an imperial (SAE) tap. The size 6-32 refers to a #6 diameter with 32 threads per inch.
