Review on 🔩 Tegara Style Bearing Collet 202 1574: Enhanced Performance with Precision Engineering by Jeremy Bradford

Can easily prevent the collet from rotating around the cone when tightening the collet nut, making it easier to tighten the cone and the Holding collets in a specific orientation relative to each other while tightening when you need to try multiple position collets to adjust runout. The only criticism is that 4 slots on the nut means using a single tooth wrench versus 6 slots on quality collet wrenches.
