Bought this set Oct 28, 2026. This is my first experience with collets I can use in my benchtop lathe. Placing the collets in the collet chuck holder was simple and the pieces worked as expected. Their craftsmanship and quality look very good. The collet set has most any size I could possibly used. I am pleased with my purchase.
