Meet the Wiseman Threading Tools Spiral Flute Metric HSS Tap Right Hand - M30x2, a precision internal-threading tap built to deliver dependable, repeatable results in metalworking projects. This high-speed steel ground tool is uncoated and designed for general-purpose use, with ISO 529 dimensions that ensure reliable compatibility with standard hole sizes in a wide range of setups.

The spiral flute geometry is engineered to evacuate chips efficiently as you cut, which is especially beneficial when threading in blind holes where chip buildup can cause binding or incomplete threads. This design helps maintain steady torque, reduces the risk of tap breakage, and supports cleaner thread surfaces, making it a preferred choice for production-like tapping work as well as shop-floor repairs.

• Spiral flute performance: optimized chip evacuation for deeper or blind holes, improving finish and reducing torque spikes during cutting.
• ISO 529 compliant: built to standard specifications so it fits predictable hole sizes and tooling setups.
• HSS ground and uncoated: offers robustness for general-purpose threading across a range of metals with reliable cutting action.
• Right-hand thread: designed for typical internal threading tasks in metalworking projects, pairing well with standard assembly practices.
• Versatile use cases: effective for both through holes and blind-hole work with proper lubrication, enabling clean, accurate M30x2 threads in steel, cast iron, and nonferrous metals.
• Practical tapping guidance: for optimal results, use appropriate cutting fluid and follow recommended speeds and feeds to maximize tool life and thread quality. RPM and feed guidelines can be calculated to balance material hardness and tap geometry.

For professionals and skilled hobbyists alike, this M30x2 spiral flute HSS tap offers a reliable path to precise, repeatable threads without the fuss of inconsistent results. Whether you’re refurbishing a machine component, fabricating a new housing, or performing on-demand repairs, this tap helps you achieve accurate thread engagement with minimal hassle—backed by Wiseman’s established threading tools heritage.
