Mini Electric Belt Grinder Machine, 7 Speed Adjustable Belt Sanding Polishing Machine, Electric Bench Belt Sander for Turning/Plastic Polishing/Knife Edge/Wood

Anyone know what size polishing wheels they are.

Looks like a great product for the hobbyist, unfortunately the polishing wheel runs too slow for the job it was bought for, there just seems to be a lack of torque for the buffing procedure. Maybe it was designed for much smaller jobs than I required, I guess it would be Ideal for model makers !!

Doesn't give any instructions how to fit hard wheel

Great little machine, not noisey great range of belts to get started get a grinding wheel dressing tool and once balanced. Really great little machine for lots of your maintenance and hobby work, all this at an excellent value for money price.

Worked nice for my project I has to do.

Nice and small but will need screwing onto bench as it vibrates. Not overly powerful and the polishing part is awkward to get to as it rotates with the sander part. You can't turn one part on so all the machine is going at the same time. Ok for light work but not that powerful

Sanding

White bits all over the place, every time i use the polishing mop. The grinding wheel, when i worked as an engineer, i used a grey wheel to remove most of the metal, then switched to the pink one to grind an edge on a tool or drill. You grind a drill, you never sharpen one 😜 Ive always wanted one of these, the flat sanding belt is great, it also comes with extra sanding belts So apart from the polishing mop, everything else was just OK Dont forget to put on goggles, when ever your using this machine. Also need a flexible folding sheet, also available on Amazon, to catch all the metal that flies out the back. Cheers
