03B094 - Walter 9/16-18 NF High Speed Steel Taper Tap

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.
