The Wiseman Threading Tools Bottom Lead Metric HSS Tap Right Hand - M22x1.5 is a purpose-built internal threading tool designed for accuracy, durability, and repeatable results in metalworking projects. This uncoated, general-purpose tap is ground from high-speed steel to deliver clean, precise threads that stand up to daily workshop use.

• Material and finish: High-speed steel ground for sharp cutting edges and dependable performance in a range of metals. Uncoated finish helps bite into steel, cast iron, and aluminum with steady lubrication.
• Thread specification: Right-hand M22x1.5 threads, conforming to ISO 529 dimensions for compatibility with standard nuts, inserts, and threaded components.
• Lead design: Bottom lead (bottoming) construction provides full-thread engagement, making it especially effective for deep or blind holes where complete thread formation is required.
• Use cases: Ideal for fabricators, machine shops, and DIY enthusiasts who need to cut precise internal threads in metal housings, brackets, housings, and other 22 mm diameter components.
• Versatility with equipment: Compatible with common tap wrenches and drill-powered tapping setups; pair with appropriate cutting fluid or light oil to extend tool life and improve thread quality.
• Durability and consistency: Ground tool geometry delivers uniform pitch and accurate thread profiles, reducing the risk of cross-threading and improving repeatability across multiple holes.

Why choose this Wiseman tap? It combines a robust HSS core with a precise, ISO 529-compliant profile and a bottom-lead design that starts cutting smoothly and maintains alignment through depth. The result is clean, strong M22x1.5 threads every time—whether you’re fabricating new parts, repairing damaged threads, or restoring precision fastener fits in metal assemblies. For professionals and serious hobbyists alike, this tap offers reliable performance, predictable results, and a long service life in demanding workshop environments.
