This is not just another random orbital — it’s the only one of its kind in the world. Powered by Hutchins’ patented Hi-Speed Reinforced Motor and exclusive captive-orbit counterweight system, the Model 3570 Super-3/16" delivers a sanding experience no other air sander can match.
The Problem with Sanding Power and Random Orbitals
Traditionally, offset is a tradeoff: the larger the orbit, the faster it cuts — but at the cost of precision and fine control. A standard 3/16" offset balances speed with smoothness, while a 5/16" offset cuts faster but sacrifices control and finish quality.
The Hutchins Breakthrough
The 3570 breaks the rules. By combining a captive-orbit counterweight system with a supercharged 3/16" offset, it transforms a standard orbit into something completely new: the Super-3/16". The result:
-
40% more cutting power than a conventional 3/16"
-
25% more cutting power than even a 5/16" sander
-
All with the low vibration and long bearing life of a standard 3/16"
In short: faster, smoother, and longer-lasting — no compromise.
Built for Professionals
With speeds of 13,000+ RPM, a lightweight 2 lb. 5 oz. body, and 6" or 8" pad options, the 3570 is equally at home on large panels, fine prep, or aggressive leveling. And because it’s still protected by a live Hutchins patent, no other sander can touch it.
