Gem Faceting Machine - 7-Speed Adjustable 1600-3300RPM Bench Grinder for Cutting, Carving & Polishing Gemstones, Jade & Jewelry (US Stock) - Perfect for Lapidary Work, DIY Jewelry Making & Stone Crafting

Can’t be used unless it’s clamped to the bench. The only instructions are pictures. Hole for the coolant tube too small had to be reamed out to fit the tube. The box to catch water is a joke. I’ve he’s the machine for over a week and can’t use it until I figure out how to get water to the blade etc without flooding my shop. Unless you’ve got an engineering or mechanical background don’t even bother. I’ve yet to discover whether it will actually do what they claim it will do
