OVERVIEW

Precision Threading with Walter HSS Taper Taps

The Walter 03B094 is a premium-grade 9/16"-18 NF (National Fine) Taper Tap designed for industrial metalworking applications where accuracy and tool longevity are paramount. Manufactured from high-quality High Speed Steel (HSS), this cutting tool is engineered to withstand the thermal and mechanical stresses of threading tough materials, including stainless steel, mild steel, and aluminum alloys. Unlike carbon steel taps, HSS maintains its hardness at higher temperatures, allowing for faster cutting speeds and a significantly longer service life in production environments.

This specific tap features a "Taper" chamfer, which is characterized by a gradual cutting angle distributed over 7 to 10 threads. This geometry is critical for the initial alignment of the thread. By spreading the cutting load over a longer length, the taper tap requires less torque to start the thread and naturally aligns itself square to the hole, reducing the risk of cross-threading. It is the preferred choice for starting new threads in through-holes or for the first pass in deep blind holes.

Walter Surface Technologies employs precision grinding processes to ensure that the thread profile is sharp and accurate to strict tolerances. This results in threads that meet specific class-of-fit requirements, ensuring fasteners engage smoothly without binding or excessive play. The tap is hardened and tempered to provide the optimal balance between hardness for cutting edge retention and toughness to resist breakage under torque. Whether used in a hand tap wrench or a machine setup, the Walter 03B094 delivers consistent, high-quality results.

Key Technical Benefits:

  • Material: High Speed Steel (HSS) for superior heat resistance and wear life.
  • Chamfer: Taper style (7-10 threads) for easy starting and alignment.
  • Thread Profile: Precision ground for reduced friction and accurate fitment.
  • Versatility: Effective on ferrous and non-ferrous metals.

FAQ

A taper tap has a chamfer of 7-10 threads, making it easier to start a thread straight. A plug tap has a shorter chamfer (3-5 threads) and is typically used after the taper tap to thread closer to the bottom of a hole.

It is manufactured from High Speed Steel (HSS), which offers superior hardness and heat resistance compared to carbon steel taps.

Yes, because it is made of HSS and precision ground, it is suitable for tapping stainless steel, provided you use proper lubrication.

The thread size is 9/16 inch with a pitch of 18 threads per inch (NF - National Fine).

Yes, for a 9/16"-18 thread, a specific tap drill size (typically 33/64" or similar depending on the desired thread percentage) is required to ensure the tap cuts correctly.

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 plug or bottoming tap to finish a blind hole.

Absolutely. Using a high-quality cutting fluid or tapping oil is essential to reduce friction, clear chips, and extend the life of the tap, especially in harder metals.

NF stands for National Fine, which indicates a finer thread pitch compared to National Coarse (NC). Fine threads are often used for greater strength and precision adjustment.
