What it is

JOOLTOOL is a California tool maker that sells its own bench-top grinding, sanding and polishing machine, the JOOLTOOL, direct online, with kits for jewelry, stones, glass and enamel, resin and sharpening. Its mission statement says it “works with 3M Abrasives to bring premium polishing, finishing and sharpening solutions to everyone.” The Our Story page says the founder grew up working in a father’s jewelry business and designed the JOOLTOOL and a patented See-Thru Technology to make work “easier, safer and more productive.”

For lapidary, the shop has a JOOLTOOL Lapidary Kits collection (“For Stones”). The kit pages say they take a rough stone to a high polish using 3M diamond abrasives, from very coarse grinding through 3,000, 8,000 and 50,000 grit diamond polishing and a 100,000 grit cerium oxide polish.

Who it’s for

Hobby and jewelry cabbers who want a small, quiet bench machine rather than a full-size wet cabbing unit, people who work with soft stones like turquoise, and jewelers who want one machine for both metal finishing and stone polishing.

Why it’s listed

It is a first-party maker that sells its own lapidary machine kits and abrasives through its own shop, with printed prices, kit contents and a written return policy. It appears elsewhere on Lapidary Plaza only as a brand that another dealer carries.

Shipping (shipping policy): most products are made to order, so processing time is added to carrier transit time.
Small source note: the shipping policy names AVASY Inc and SAAVY Inc alongside JOOLTOOL, and the home page footer gives no street address. The Montebello address comes from the refund policy. The shop also runs an authorized-distributor network, and distributor purchases follow each vendor’s own return policy.
