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.

Random Orbital Sander Diameter Orbit Diagram

The D3 Random Orbital Sander series is comprised of:

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

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.

Abrasive Sanding Belts

Aluminum oxide sanding belts can be used on all metals and both hard and soft woods. Standard grade aluminum oxide belts have an x-weight backing and are used as a general purpose approach to sanding wood and sanding metal. Premium grade aluminum oxide abrasive sanding belts have a y-weight, poly-cotton backing . More grain and a heavier backing on the premium sanding belt results in a better finish and longer life. Open coat, poly-cotton aluminum oxide sanding belts are also available and have a specially coated backing which provides high performance for washable sanding belts. This coated abrasive sanding belt is great for hard and soft woods and soft metals. Wider grain placement helps the belt in loading applications.

AA Abrasives 35373 Knotted Wire Cup Wheel and an Angle Grinder Removes Rust from Steel and Iron

Rust and oxidation are similar processes that lead to corrosion of metals. Iron and steel rust, while aluminum and brass oxidize. Over time exposure to oxygen and moisture will cause rust and oxidation.  If left untreated, the rust and oxidation will continue to corrode the metal. In time an object may become so corroded it can no longer be used. 

To remove rust from industrial iron or steel installations use a #35373 knotted wire cup wheel on a Metabo W8-115 - 4 1/2" Angle Grinder.

The Weiler Brush 13286 is an equivalent knot wire cup product for removing rust and oxidation from metal surfaces.

For larger surface removal or preparation, use Metabo W24-180 7" Angle Grinder with AA Abrasives #35381 - 5" Cup Wire Brush Knotted Wheel or a Weiler Wire Wheel 12276.

Strip-It Lava Disc

Another abrasive product to consider is the AA Abrasive 33936 - 4 1/2" Strip-It Lava Disc

AA Abrasives 33936 Strip-It products-Lava Wheels made of abrasive grains and resins which are bonded to a strong nylon filament resembling black lava. Strip-It lava wheels are recommended for aggressive mechanical cleaning operations. The porous structure of these lava wheels allows for reduced loading and a cooler cut. Strip-it lava wheels are excellent for providing consistent surface finishes.

HOW DO NON WOVEN ABRASIVES WORK?

Non woven abrasives provide a controlled, sustained stock removal process. The "open weave" three-dimensional material construction provides a continuous supply of new grain when fiber and old grain wear away. The flexible "spring" design reduces the chance of undercutting or gouging a work product. Nonwoven abrasives can be divided into two categories:

1. Clean and Finish - Nonwoven clean and finish products are generally hand-operated. They are not as strong in nature as surface conditioning products because less grain, fiber and resin are used in their production. Clean and finish products include flap wheels, hand pads, sheets and rolls.
2. Surface Conditioning - Surface conditioning products are generally used near the end of the manufacturing process. Surface conditioning refers to the ability to change a product's surface, without removing or damaging the base material. These products are used in mechanical operations and include discs and belts. See our quick change surface conditioning discs.

How to Use Surface Conditioning Disc to Blend Surface Scratches on Stainless Steel 

This video shows the fine maroon hook and loop surface conditioning disc 33416 being used on stainless steel to blend surface scratches in order to achieve a uniform finish.
