Heavy Duty Stainless Steel Expanding Ring Mandrel - Allen Key Included, Ring Sizes 4-7, For Lathe Turning and Making

I started wooden ringmaking and was looking to see if I could use this to turn my drill into a mini-lathe. This fit my standard Dewalt drill chuck and the ring stayed secure when I made sure it was snug on the mandrel and tightened down on the hex key (don't want to crack the wood but you do need it to be secure). I basically laid a piece of sand paper down and just ran the ring over it at while it was spinning. It worked surprisingly well and got a really great finish. It will also fit very nicely in a drill press for similar work I believe, though I haven't validated that yet. Product seems like good quality.

AWESOME tool that comes in handy. Great quality. I bought this when I was making my brother’s wedding ring (titanium) and needed a way to safely hold it in my lathe for grooving and polishing. This thing works GREAT!! It does work with a live center as well, however I recommend using a bull-nose if you have one, but it will work with a fully tapered/pointed center as well (i tried both just to see). 9.5/10.

While the mandrels work fine for my use case, the quality of the machining is not what I expected for the price. If you’re a serious lathe-using pro, maybe another brand would be more suitable. If $100 sounds like a good deal for three mandrels, and pro shop quality is not a priority, this set will work. It gets a 4th star because of the 3-piece set and the price. Other than that I would say it’s rally and honest 3 star product at best.

The media could not be loaded. The machining is not that accurate as it says. It’s vibrates a lot.

The tools seem well made, round stock centers easily on the mandrel and tightens easily with the included wrench. Good finish, no burrs.

I've purchased others that are more expensive but harder to use as an amateur. This is so simple & lightweight. No manual is needed.

Delivery was excellent. The mandrels is a very good quality and works very well.

I needed a mandrel that would work for 7 1/2 and size 10- 12 . These are either too large or too small
