Wiseman Threading Tools: M27x2 Taper Lead Right-Hand HSS Tap (Uncoated, Ground)

When precision matters, this Wiseman M27x2 HSS tap delivers clean, accurate internal threads with dependable performance. Designed for general purpose tapping, the tap is uncoated and ground to a consistent geometry that produces true thread forms in a variety of metals. The taper lead helps start the thread smoothly, reducing the chance of cross-threading and binding during the initial cut.

Key features

• Size and thread: M27x2, right-hand thread, sized for common metric assemblies and in line with ISO 529 dimensions.
• Lead type: Taper lead for easier alignment and gradual engagement, especially helpful when starting threads in tougher materials.
• Material and finish: High Speed Steel (HSS) ground, uncoated for general purpose use across metals such as steel, aluminum, and brass.
• Construction: Precision-ground taps that maintain accurate pitch and flute geometry for consistent chip removal and thread quality.

Use cases and applications

This tap is ideal for creating or repairing internal threads in machining, fabrication, and maintenance tasks. Use it to tap holes in ferrous and non-ferrous metals where a reliable M27x2 internal thread is required—whether you’re building a custom bracket, repairing a damaged boss, or producing components that must thread cleanly with standard hardware.

Practical guidance for best results

• Match the tap to the correct pilot hole size per ISO 529 guidelines for M27x2 to achieve optimal thread depth and strength.
• Apply a suitable cutting fluid or lubricant to reduce heat, improve chip evacuation, and extend tool life.
• Use a tapping wrench or a machine tapping setup that keeps the tap perfectly perpendicular to the workpiece to prevent crooked threads.
• Begin with a light touch, maintain steady rotation, and back off slightly after a few turns to break and clear chips. Finish with a controlled pass to establish the final thread form.
