• High-speed steel ground taps provide sharp cutting edges and lasting performance under manual use.
• ISO 529 compliant geometry ensures compatibility with standard nuts, inserts, and threaded components across metalworking applications.
• Includes taper, second (plug), and bottom leads to cover a range of hole depths and thread quality from first pass to final cleanup.
• Uncoated for straightforward cutting behavior and easy inspection of chip formation and wear patterns.

Practical use cases

Perfect for hobbyists, makers, and professionals who need dependable hand threading tools. Ideal for tapping soft steels, aluminum, brass, and other common metals where a precise M12x0.75 thread is required. Use with a standard hand tap wrench, a light lubricant, and steady, even turns to achieve true, bur-free threads. The taper-to-bottom design helps break chips smoothly and minimizes ailing chatter, giving you a clean finish even in through-holes or shallow blind holes.

How to get the best results

1. Prepare the hole with an appropriately sized pilot drill for M12x0.75 threads.
2. Apply a suitable cutting fluid to reduce friction and improve thread quality.
3. Begin with the taper lead, then progress to the second (plug) lead, and finish with the bottom lead as needed.
4. Turn slowly clockwise, maintain light, steady pressure, and back off periodically to break and clear chips.
5. Clean, dry, and store the taps after use to preserve the uncoated edges for future jobs.
