NuoDunco 3-in-1 Mini Belt Sander Bench Grinder 7-Speed for Knife Making | Mini Benchtop Belt Sander & Polisher for Metal Woodworking, Jewelry Making, Knife Sharpening, Resin Crafts & Stained Glass.

I didn’t realize the voltage regulator on the power supply and once I did the sucker actually works great for the size and I’m happy with it

If I could give it zero stars, I would. Ordered one. It broke after 1st use. Gave it the benefit of the doubt and got a replacement. That one also broke after first use. Spend your money elsewhere

This inexpensive, very compact device does what you need it to do and it seems like it will hold up over time to keep on doing what you need it to do. I was impressed by the design and apparent quality of components. Time will tell if longevity is a part of the quality, but for now it appears to be so. Belt sander, grinder, polishing wheel are all included. A circular saw blade may be attached at optional cost. The "brick" style power cord includes an 8 position switch to select rotational speed of all three features; sander, grinder and buffer. The electrical components all seem to be good quality.

I have had this tool for 6 months and it has been fun to use. It gets "only" three stars because it is limited in the application lacking power--but that is what one should expect with a tool like this. I like its versatility--grinding, shaping and polishing small objects. It doesn't have a great build quality, but certainly good enough for the price.

Easy to set up and works as designed. This thing is very small though, it works for me but I underestimated exactly how small it is.

Small but worthy

Does exactly what I need it to do. Love the fact that the speed settings go up pretty high and it stills stay stable on the table. Very powerful I purchased for resin.

Must of been for a pocket knife and had no degree lines if you was sharpening a knife
