I found some photos that are small enough so I can show you what underground mining equipment looks like. The first 4 are an Atlas Copco 1 boom jumbo hydraulic/electric drill. Next 2 are an Eimco Jarvis Clark 220 scooptram. Last 2 pictures are a Wagner ST2 scooptram.Sounds really interesting and a different world than my daily grind - don't be shy with the stories and photos, bet I'm not the only one who would find it interesting

Been considering the 3/8” or 1/2”, but I already have a micro-belt grinder that uses the 3/8” belts so good to see your feedback.I have the 3/8" Milwaukee M12 version & I'm very pleased.
BTW I took a gamble on some Ali replacement belts & they seem every bit as good as what was packaged under label. Now it might be one of those things where a 3M belt kicks its but but 3x the cost, haven't gotten that far yet. Also while hunting on Ali, discovered belts which are like 3M scuff pads in same size. They work very nice for blending & finishing metal, so far anyway

I can only assume it would because that size is what I ordered from Ali. They fit & run well. Maybe these cordless electric units are designed to run same belts as existing pneumatics so they didn't have to reinvent the size? The Milwaukee pulley wheel inside the housing has vertical ears so the thicker abrasive belt is more or less laterally contained. Next time I'm in the shop I'll measure the belt thickness. From memory they were 3-4mm thickness maybe? 3M would, I'm sure, be a better & longer lasting product. The only ones I could see online were either USA based or autobody shops in larger qty, so the Ali variety pack was a short term gap fix.Have you tried or do you know if the Milwaukee can use the 3M 3/8” x 13” Scotch-Brite belts?
Thanks, Charlie
Thanks; I picked up a medium & a fine from McMaster and they fit & run ok on the micro grinder:I can only assume it would because that size is what I ordered from Ali. They fit & run well.

I've got a 10mm x 330mm belt sander/grinder that I have fitted with a Scotch-Brite belt for deburring small parts:I was getting tired of deburring and filing burrs off pieces so I bought this little band sander a few years ago ($21 from Aliexpress).
I also picked up six each of 80, 120 and 180 grit belts ($18 for the lot).
It's mind blowing to me that they can sell something like this for $10. I wouldn't even push the start button on the lathe or unlock my toolbox for $10. I sort of consider about $50 to be the minimum profit on any item that I have to put into the mail.I cannot find a listing for mine (I bought it in 2021).
But here is a similar unit from AliExpress.
It is listed for US$9.98 ea.
If you get on the AliExpress site,
Just search for “mini belt sanders”.

Last thing I need is a 4th battery system (~US$300 including battery & charger); besides, I already have a better Craftsman (yes, it's corded but has an extra long cord):Got another one for you guys, might be less useful in the machining world, but handy if you do other stuff:
