OVERVIEW

Precision Threading with Walter High-Speed Steel Taps

The Walter 3/8"-24 NF Taper Tap (03B064) represents the pinnacle of threading technology for industrial applications. Manufactured by Walter Surface Technologies, a leader in metalworking solutions, this tap is engineered to meet the rigorous demands of professional machine shops and maintenance departments. Unlike standard carbon steel taps that dull quickly and are prone to breakage, this tool is crafted from premium High-Speed Steel (HSS). This advanced material composition ensures exceptional hardness and heat resistance, allowing the tap to maintain its cutting edge even when threading tough materials like stainless steel and alloy steels.

One of the standout features of this product is its precision ground threads. While cheaper taps often feature cut threads that can be rough and inaccurate, Walter's ground threads provide a smooth, exact profile. This results in lower friction during the tapping process, reduced torque requirements, and ultimately, a cleaner, more precise thread form. The tap has been meticulously hardened and tempered, a heat-treatment process that balances hardness with toughness, significantly reducing the risk of the tool snapping inside a workpiece—a costly and frustrating scenario for any machinist.

The Taper style chamfer is specifically designed with a gradual lead of 8 to 10 threads. This configuration makes it the ideal choice for starting new threads in a drilled hole. The long taper helps align the tap perpendicular to the workpiece, ensuring the thread starts straight and true. It distributes the cutting load over more teeth, which is particularly beneficial when tapping hard materials or when working by hand. Whether you are manufacturing new components or repairing critical machinery, the Walter 03B064 delivers the reliability and performance required for high-stakes industrial environments.

FAQ

A taper tap, like this Walter model, has a longer chamfer (8-10 threads) which helps align the tap and start the thread easily. A plug tap has a shorter chamfer (3-5 threads) and is used after the taper tap to thread deeper into a hole.

Yes, this Walter tap is made from High-Speed Steel (HSS) and is hardened and tempered, making it suitable for cutting threads in tough materials like stainless steel, as well as mild steel and aluminum.

NF stands for 'National Fine'. It indicates that the thread pitch is finer (more threads per inch) compared to a National Coarse (NC) thread of the same diameter. This 3/8"-24 tap has 24 threads per inch.

Yes, using a high-quality tapping fluid or lubricant is highly recommended. It reduces friction, dissipates heat, and helps clear chips, which significantly extends the life of the tap and improves the quality of the threads.

While it can be used in machine operations, taper taps are specifically designed to be excellent for starting threads by hand. If using power tools, ensure the torque and speed are carefully controlled to prevent breakage.

For a 3/8"-24 NF thread, the standard tap drill size is typically a letter Q drill bit (0.3320 inches) or an 8.5mm bit, depending on the desired percentage of thread engagement.
