What Are Thumler's Tumblers?
"Thumler's Tumblers" is the brand name of rock tumblers manufactured by Tru-Square Metal Products Company of Auburn, Washington, since 1960. They are quality machines that will last for years. "Thumler" is the family name of the people who invented these popular tumblers - and members of their family still run the business and manufacture the tumblers today. Every Thumler's Tumbler has a factory warranty that allows you to buy with confidence.

Many of our customers tell us that they received a Thumler's Tumbler when they were young, used it with their children, and now use that same tumbler with their grandchildren. We received an A-R2 tumbler as a gift from our father in the 1960s - and that tumbler still works great today! He never knew where that gift would lead us.
