03A104 - Walter 10-32 NF High Speed Steel Taper Tap

Precision Threading with Walter High Speed Steel Taps

The Walter 03A104 10-32 NF Taper Tap is an industrial-grade threading tool designed for professionals who demand accuracy and durability. Manufactured from premium High Speed Steel (HSS), this tap is engineered to withstand the high thermal loads and abrasive nature of cutting threads in modern industrial metals. Unlike standard carbon steel taps that may dull quickly or chip when encountering hard spots, Walter's HSS composition ensures a cutting edge that stays sharp longer, providing a lower cost-per-thread over the lifespan of the tool.

This specific model features a "Taper" chamfer, characterized by a gradual cutting angle over the first 7 to 10 threads. This design is critical for the initial alignment of the thread, distributing the cutting load across more teeth and significantly reducing the force required to start the cut. This makes it the ideal choice for manual tapping operations or for initiating threads in through-holes where alignment is paramount. The threads themselves are precision ground, not rolled, which guarantees tight tolerances and a smooth finish on the internal threads of your workpiece.

Versatility is a key component of the Walter 03A104. It is rated for use on a wide spectrum of materials, including mild steel, aluminum, and difficult-to-machine stainless steel. Whether utilized in maintenance, repair, and operations (MRO) or production environments, this tap delivers consistent performance. The 10-32 National Fine (NF) configuration is a standard specification for applications requiring finer adjustment or greater tensile strength in the fastener assembly. By choosing Walter, you are investing in a tool that reduces breakage risk and ensures every hole is tapped to specification.
