## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice design, works great but you may need to make a spacer for some lathes
*by H***R on April 4, 2025*

The media could not be loaded. I watched a few Youtube videos before purchasing this product and it seemed to bolt on to some lathes without any modification. However, on my new Vevor 7 X 16 lathe it was way too short to reach the chuck centerline. It needed a .485 thick spacer to raise the cutter to material centerline. Actually I just got a piece of .500 aluminum and fabricated the spacer. This left it .015 high but it works great for the moment.The bolt holes were no problem they all lined up perfectly and the stock screws were correct although on the very short side. It was only the height that needed adjustment.So FYI : The height of the cutter from the base on the one I received was 2.225 in / 56.5mm. You may want to check this dimension on your particular lathe to determine if you will need a spacer.I am very happy with this product. If it is mounted and used properly it is rigid based on the design, the bearing provides a very smooth turning action, there is no chatter at least on aluminum and it produces perfect chips if speeds and feeds are correct. I believe it is the best design out there. However, I have spent time improving the rigidity of my lathe. There is plenty of room for improvement on these Chinese lathes

### ⭐⭐⭐⭐⭐ Works great right out of the box.
*by R***U on November 24, 2024*

I installed this on my 7 X 12 lathe in minutes with no modifications necessary. I turned my first ball right away and had a blast doing it. I’m no expert and it was very easy to figure it out. It’s easy to switch back and forth between concave and convex configurations.

### ⭐⭐ Doesn't come with cutter inserts
*by J***N on January 14, 2024*

Product seems nice, smooth action after degreasing. Product didn't ship with cutters, so looks like you're on your own trying to figure out what insert it takes.
