Wiseman Threading Tools Hand Tap - Bottom Lead Tap - +0.015 Tolerance - M20x2.5

The Wiseman Threading Tools Hand Tap is built for precision with every turn, letting you cut clean, repeatable internal threads by hand. Designed for accuracy, these hand taps deliver a +0.015 tolerance, so your threaded holes thread true and mate reliably with the corresponding screw or bolt. The M20x2.5 specification tells you the exact diameter and pitch you’ll create, making this tool a dependable choice when dimensional control matters in your project.

Bottom Lead Tap technology guides the thread profile smoothly into the material, helping you start the cut squarely and reach full thread depth with confidence. This design reduces chatter and minimizes thread deviation, which means less rework and tighter fits in blind holes or complex assemblies.

Durable construction ensures long-lived performance in demanding workshop environments. Built to withstand repeated use, these taps maintain consistency over time, preserving accuracy even after many tapping sessions. When quality threading matters, you can rely on the Wiseman tap to deliver steady results, component after component.

• Thread size and tolerance: M20x2.5 with +0.015 tolerance for precise, uniform internal threads.
• Bottom Lead design: facilitates clean starts and full-depth threads, especially in blind holes.
• Hand tapping performance: optimized for manual operation, delivering consistent thread quality without specialized equipment.
• Durable construction: built for longevity in busy shops and challenging jobs.
• Ideal use cases: maintenance, repairs, prototyping, and fabrication tasks where exact internal threads are critical.

To get the best results, establish a steady, straight alignment as you begin the cut, use appropriate lubrication to reduce friction, and advance the tap gradually to maintain the +0.015 tolerance throughout the process. The Wiseman Hand Tap is a reliable companion for anyone who values precision threading and repeatable performance in metalworking projects.
