Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M30x1

Engineered for precision and speed, the Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M30x1 is a robust internal threading solution built to meet the demands of professional machinists and serious hobbyists alike.

• High-speed steel, ground and uncoated: This general‑purpose tap delivers clean, accurate threads and can be sharpened or reground to extend life. The uncoated surface improves lubrication compatibility across a range of materials.
• ISO 529 compliant: Designed to produce consistent thread forms that match standard M30x1 holes in metal workpieces, ensuring interchangeability across tools and components.
• Right-hand thread with second lead: Optimized for faster cutting in long, through or blind holes. The second lead minimizes tapping time and reduces the effort required during production runs.
• USA plug lead design: Engineered for reliable start-up and alignment with common tapping setups used in U.S. workshops.
• Versatile, general‑purpose tapping tool: Ideal for aluminum, mild steel and other common metals when paired with appropriate cutting oil or lubricant.

Practical use notes: For best results, secure your workpiece, use a dedicated tapping lubricant, and apply steady, clockwise rotation with even pressure. Let the tap cut at its own pace; avoid forcing it, and back off periodically to break chips and prevent binding. If long-term durability is needed, consider re-sharpening the flutes with the proper tooling after wear.

Who benefits: machinists who need precise internal threads in recessed housings, automotive technicians fabricating engine blocks, or makers building custom projects where an accurate M30x1 thread matters. This Wiseman tap pairs with standard drilling and tapping setups and complements other Wiseman threading tools in your workshop.

In comparison to alternatives, this uncoated HSS tap offers predictable performance and true thread form with ISO 529 standards, while the second lead reduces overall cycle time on longer holes. It’s a strong, durable choice for reliable thread production that can be retrued and reused across multiple jobs.
