4 inch Tapered Spindles

I needed a replacement set for my polishing lathe, and these threaded perfectly into the existing nuts without any wobble. The hardened tool steel feels a lot more durable than the cheap sets I've tried before.

The threads cut smoothly into my motor shafts, much cleaner than the generic ones I’ve used before. These hardened steel spindles feel sturdy and should last through several polishing jobs. Only wish they came in a smaller pack for folks needing just two.

I only needed a pair, but the four-count package meant I had spares for a future project. The left-hand threads on this second set were very clean and seated perfectly on my DC motor shaft. Works great for my polishing station, though I wish the package had clearer labeling on the thread direction.
