The DS3011 by Inter-Tool is the gold standard in planetary polishers. Its triple-sealed bearings and gear/chain drive make it extremely reliable and durable. There is no belt to break, and the bearings don’t wear down due to grit. The three heads are extremely well-balanced for an even polish with very little effort.
This machine is worth a couple hundred extra dollars versus the cheaper alternatives, which is why it is the only planetary polisher that The Concrete Countertop Institute recommends.
(Note: Inter-Tool also offers this machine in 230V, 5oHz power for the European and Australian markets. Please contact us for a quote if you require this configuration.)
Here are some photos from the February 2021 class where instructor Caleb Lawson used his 15 year old DS301! These machines are EXTREMELY reliable!!!
