The Wiseman Threading Tools Spiral Point Metric HSS Tap Right Hand - M15x1 is a precision-ground tapping solution designed for fast, reliable metal threading. Crafted from high-speed steel and offered uncoated for consistent, predictable cutting, this tap adheres to ISO 529 dimensions for dependable performance in both machine and hand tapping setups.

Featuring a spiral point (gun nose) and a right-hand thread, this tap aggressively engages the workpiece and pushes chips forward as you cut. The spiral-point geometry makes it especially effective for through-holes and long threaded runs, reducing clogging and easing alignment. The uncoated finish provides a straightforward cutting action, letting you feel and control the cutting process with confidence.

Key benefits

• Spiral-point geometry to improve chip evacuation and speed start in through-holes
• Gun-nose tip concentrates cutting action where the thread begins for cleaner starts
• ISO 529 compliant M15x1 size ensures compatibility with standardized metric threads
• General-purpose tool suitable for steel, aluminum, and other machinable metals
• High-speed steel (HSS) ground surface offers durability and consistent performance without coatings

How to use

Begin with the correct tap drill size per ISO 529 charts. Apply a light cutting fluid or oil to minimize heat and extend tool life. Align the tap precisely with the hole, apply steady, even pressure, and rotate smoothly. Avoid forcing the tap; back off periodically to clear chips and continue until the full M15x1 thread is formed. After tapping, clean the hole and remove any residue.

Ideal applications

Perfect for workshop projects, fabrication shops, or DIY tasks that require robust M15x1 threads. Use it for through-hole assemblies in steel frames, aluminum housings, or any project needing reliable metric threads with fast, predictable results.
