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 3570VA 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 3570VA 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, fine control, and long bearing life of a 3/16"

Faster, smoother, more precise — with 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 3570VA is equally at home on large panels, fine prep, or aggressive leveling. The integrated Vacuum Assist system keeps dust out of the air and off the surface, creating a healthier workspace and cleaner finish. And because it’s still protected by a live Hutchins patent, no other sander can touch it.

Random Orbital Sanders

  • Because they leave no repeating pattern, they are often used for final preparation before and after the painting application.
  • Even though they are popular for finishing, there are Random Orbitals that are excellent for all stages of sanding.

Orbital Sanders

  • These sanders are known for consistent results and excel where you need solid material removal and flexible performance.
  • Because of their regular orbits, these sanders are well-liked for material processing that is more forgiving than straight-line sanders.

Straight Line Sanders

  • Excels at blocking and material processing.
  • Low vibration and smaller "shortboard" options available.

Vacuum Sanders

  • Vacuum Sanding have both Vacuum-System Ready and Dust-Free Versions. Dust-Free can perform vacuum operations without a vacuum system.
  • Every Model has a Vacuum or Dust-Free Version Available. All Sanders can be later upgraded to vacuum-compatability.

Water/Wet Sanders

  • Ideal for finishing and more delicate processing where heat is a concern. Also used to assist in dust control where vacuum systems are unavailable or unreasonable to equip.
  • Our Water Sanders are equipped with a Patented "Thru-the-Pad" distribution system that enables a steady, regular flow of water to your surface. Most Models are equipped with a filtered 'water bell' that can be dropped into any source of clean water (like a 5-gallon bucket).

Speed Files

  • Good for careful planing or finishing up blocking stages where you want that extra bit of control over your contours.
  • Extremely popular is our PF-16 which is made from a firm plastic frame. Many customers like the rigid structure that gives just the perfect amount of flex when required.
  • The AF-16 was featured in the movie, Shawshank Redemption in the last scene when Andy Dufrene sands his boat on the beach in Baja California.

Accessories

  • Highlights:
  • Grounded air-lines. Made with food-grade hose that ensures clean and quality air, copper grounded lines for anti-static properties, and high-quality brass fittings. Extremely light-weight with anti-kink properties.
  • Custom-Sized Foam Interface Pads rated up to 13,000RPM.
