Wiseman M26x1.5 Right-Hand Second Lead HSS Tap — Uncoated, General Purpose

Achieve precise, durable threading with the Wiseman Threading Tools M26x1.5 right-hand HSS tap. This high-speed steel tool is ground for clean, accurate threads and is designed for general-purpose tapping across a range of metals. Its ISO 529-compliant geometry ensures compatibility with standard tooling, dies, and taps, making it a reliable choice from prototype work to small‑batch production.

• Thread specification: Metric right-hand thread, M26x1.5, engineered to exacting ISO 529 dimensions for consistent fit and finish.
• Second lead design: A double-start lead that improves entry, accelerates cutting, and reduces torque—helpful for longer holes and tougher materials without sacrificing thread integrity.
• Material and finish: High-speed steel with ground threads and an uncoated finish for robust performance, straightforward inspection of wear, and compatibility with common cutting fluids.
• Shank compatibility: Standard square shank designed for use with conventional hand taps or a tap wrench, delivering secure, repeatable turning action.
• General-purpose versatility: Suitable for a wide range of metals, including steel, cast iron, aluminum, and alloys—ideal for repair work, fabrication, and hobby machining.
• ISO accuracy: Built to ISO 529 standards, ensuring predictable thread depth and pitch when paired with the correct drill size and tapping technique.

Practical use cases include repairing damaged threads in mechanical assemblies, creating new threaded holes for fasteners in fixtures, or completing prototype components where reliable, repeatable threads matter. The uncoated HSS tap handles heat well when used with proper cutting fluid, delivering steady performance and easier inspection of wear as you work.

Tips for optimal results

1. Select a pilot drill size appropriate for M26x1.5 and deburr the hole to prevent binding.
2. Secure the workpiece firmly to avoid runout during tapping.
3. Apply a suitable tapping fluid or cutting oil to reduce heat and extend tap life.
4. Begin tapping with a steady, even feed, then back off periodically to break and clear chips.
5. Test the new thread with the mating fastener and re-tap if needed to achieve full thread depth.

Designed for professionals and serious DIYers alike, this Wiseman tap delivers dependable threading performance—combining precise, durable construction with practical features that make metalworking smoother, faster, and more predictable. Add the Wiseman M26x1.5 right-hand second-lead HSS tap to your toolkit and tackle threading projects with confidence.
