Dynabrade Dynorbital Random Orbital Sanders available at aaabrasives.com

Dynabrade Random Orbital Sanders have an innovative, lightweight design that exceeds the expectations of customers. Dynabrade makes one of the highest quality abrasive power tools made in the USA. Used in hundreds of industrial applications, these sanders are great for finishing a wide variety of materials.  AA Abrasives, Inc. is a leading distributor of Dynabrade products.

Today in the Abrasives-Sandpaper Blog we are looking at the air powered Dynabrade Dynorbital Random Orbital Sander Series – their orbit patterns and their features.

Both the spinning of the sanding disc and the movement of the disc in an elliptical pattern ensure that no single part of the abrasive material moves in the same path twice, producing a random orbital motion. This unique sanding action is designed so that there are no perceivable swirl marks on the work surface. The diagram below illustrates the diameter orbit patterns and usage recommendations. All of the Dynabrade Dynorbitals are available in your choice of 3/8”, 3/16” or 3/32” diameter orbits. There is an aggressive 3/8” orbit, a 3/16” orbit for general sanding and a 3/32” orbit that is recommended for fine sanding in light to medium applications.

1. The Dynabrade Dynorbital Supreme
2. The Dynabrade Dynorbital Silver Supreme and

1. The Dynabrade Dynorbital Supreme 56815  is a cornerstone of the orbital sander series. It features the highest RPM in the industry while working on a work surface. The Dynabrade Dynorbital Supreme line features a perfectly balanced low profile, premium urethane weight-mated sanding pad for both smoother operator performance and minimum vibration. This line of random orbital sanders features a refined ergonomic tool grip to reduce fatigue and increase efficiency with a more comfortable grip.

2. The Dynabrade Silver Supreme is the newest member in the Dynabrade Random Orbital Sander family. The Dynabrade Silver Supreme 69020 Non-Vacuum Random Orbital Sander is a favorite in this line. The Dynorbital Silver Supreme features all steel components including a steel cylinder and end plates to maximize motor performance. These random orbital sanders have a perfectly balanced weight-mated sanding pad for smoother performance and minimal vibration.

3. The Dynabrade Dynorbital-Spirit Random Orbital series is lightest tool in the series and is ideal for vertical and contoured applications.  The Spirit series features a compact grip size - a reduction of 5% from other models in the series for operators with smaller hands. The Dynorbital-Spirit models feature the perfectly balanced weight-mated sanding pad for smoother performance and minimal vibration. The Dynabrade Dynorbital-Spirit 59020 Non-Vacuum sander is a good choice.

So in review, if you need...

…a random orbital sander for heavy aggressive sanding the Dynorbital Supreme would be recommended.

…a random orbital sander for general application the Dynorbital Silver would be recommended.

…a random orbital sander for vertical or contoured sanding applications the Dynorbital Spirit would be recommended.

All of these Dynabrade Dynorbitals are available with a pad diameter of 3 inch, 5 inch or 6 inch depending on the surface you need to sand. All Dynabrade Dynorbitals are available in Non-Vacuum, Self-Generated or Central Vacuum models.
