We recently used a right-hand round threading DIE and were really impressed with the results. Based on our own experience it's the best threading tool for cutting precision threads. The die worked smoothly and created clean threads on our industrial projects. Another bonus is that its compatible with other cutting tools, making it a versatile addition to our toolbox. The only drawback we noticed is that it requires a bit of strength to use, but it's a small price to pay for such great results..
