Firstly, the operating principle of the grinding machine is the same. Use a polishing tool to smooth the surface of the material.

However, if you make an informed choice, you need to clearly understand the purpose of each type of these power tools.

A kind of grinder does okay for each task, but the other type does not produce the expected results.

For example, Random Orbit Thunder does not work in corners, but Random Orbit Thunder does. On the other hand, eccentric thunder is your first choice if you want a very smooth surface.

This article explains the difference between rotary Sander and Orbital Sander.

These handheld devices differ in the type of grinding operation and, therefore, the grinding pattern and possible applications. Examine the differences and similarities between both tools to determine their scope.

Rotary Sander Vs Orbital Sander

Basic feature

Advance grinders are equipped with a dust collection system. Construction vacuum cleaners are connected via special pipes or a dust bag.

This makes the work process cleaner, the tool itself is better controlled, and the consumption of polishing tools is reduced. It’s also much healthier, but it’s still advisable to wear a mask.

Orbital and arbitrary sanders are split into electrical and rechargeable tools based on the power source.

The benefits and drawbacks of cordless variants are self-evident: It has more flexibility and is less reliant on the electric grid. The charge time, however, limits the runtime.

Rotary sander

This device has a mass from 1 to three kg, ready with a square sole with a clamping mechanism at the edges to restore the maximum famous sanding paper.

There are also fashions with the restoration choice, the snap to the only with Velcro, which calls for Velcro-well-suited sandpaper. 

This popular sander is designed for the sensitive processing of massive flat surfaces, permitting quicker development on large chunks like flooring or slats.

Here, the selection is simple: mini floor sanders are appropriate for narrow spaces; they’re lighter and extra manoeuvrable than popular ones.

With the assist of a fine-grit abrasive, they carry out a very last sprucing of numerous surfaces: timber, plastic, and pebble.

When operating the polishing disc at maximum speed, make careful to keep the tool level on the resistance welding to the rotary motion of the disk.

However, because the edge cuts into the ground rapidly, undesired downturns can form quickly. The polishing pad’s rotational action speeds up the cleaning process significantly.

The rotating sanding, like the rotary sander, must be maintained in motion at all times. The effort involved is substantially more with a rotary sander. With the same surface integrity, the percentage removal is significantly higher with homogeneous motions.

Orbital sander

Orbit sander is regarded as the most influential and universal tool for texture polishing. Inexperienced and manufacturing territories, as well as in private use, show the best results in terms of surface quality.

Polishing and thrashing are possible by combining the rotational movement and abnormal movement of the spherical sole.

The sole rotates in orbit and, at the same time, rotates around its axis. This complex abrasive movement qualifies for effective polishing with the tiniest error.

This grinder is used for coarse or fine grinding in large areas, intermediate layer treatment of materials and coatings, polishing, along fibers, and in large areas of the entire thread. This tool is frequently used during carpentry and car paint shops.

A circular sole using Teflon is commonly fastened to the angle grinder on a felt foundation on the device, which weighs between 1 and 3 kg.

Cleats are available in 2: 125 and 150 mm diameter. Sanding engines with a 125 mm sole are more minor, lightweight, and built for further intricate work as polishing equipment with such a 150 mm sole.

The orbital sander must constantly be in movement while operating to prevent circle notches. The circular action of the polishing plate causes these notches.

Huge parts can be successfully treated because of the comparatively large sandpaper plate.

You may get excellent surface results with an orbital sander and steady motion. The orbital sander is the best tool for working on angles, corners, and even tiny workpieces.


  • Orbits work well in many applications.


  • Interior edges and slots cannot be processed with these sanders.

Rotary sander v/s orbital sander

  • Different abrasion movement

A grinding disk is used on traditional orbital sanders. This polishing blade is unconventionally oscillating. This has a flat bottom and gets up by repeatedly heading back and forth across the same manner. Fasteners or adhesives are generally used to hold the abrasive in place.

If you wish to work along borders, you must use an orbital sander. Because of its swinging action, the orbital sander produces less attrition than the rotary sander.

It does have a habit of leaving markings that show it was simply traveling back and forth through the identical movement.

Orbital sander, on the other hand, has a rounder sanding surface. The sanding surface is unconventionally rotated. The sanding sponge is often spread using a climber rope.

orbital sander

The percentage removal is considerably higher than a rotary sander because of its spinning motions. A randomized orbit sander is far more forceful when it comes to scrubbing. As a result, if you’re using the grit sanding on a rotary vs. an orbital sander, the rotary will remove the grit considerably more quickly.

  • Sanding performance

When using an orbital sander, it is possible that the sanding surface will not be regular in some areas. Because the orbital sander removes less material, the site should be treated more frequently than the rotary sander.

The sanded design is much smoother with rotary sander than the orbital sander, and the area has a softer and cleaner sanding texture.

  • Other uses

The two different sanders will be classified into two parts. Both kinds of tools work well on wooden or plastic materials.

Even so, because the rotary sander’s expulsion rate is much lower than that of the orbital sander, much time is required.

The orbit is being used for extensive areas, including such side tables. You can use a rotary sander if you want to collaborate on workpiece material with a tough exterior or several edges. The orbital sander may also be used for various tasks, including refining or scrubbing plasterboard.

  • More benefits of using an orbital sander

Rotary sanders are required for incredibly tough and unpolished bits of materials that must be straightened out before being processed.

They’re the much more strength of these two, but they’re a superior option if you need to remove many inches of abrasive material.

Furthermore, unlike paper sanders, the RO turner could be manipulated and controlled considerably more by the operator.

This implies that a rotary sander could be used as a finishing sander by switching to finer sandpaper and exerting less force, far more so than a preparation sander could be used as a finishing sander.

Rotary Sander

Orbital sanders, as previously stated, employ round sand bits attached to a polishing disc. The disc rotates and circles elliptically simultaneously, in a peculiar (odd) movement.

Rotary sanders are less prone than orbital sanders to create swirling patterns on the cloth due to their specific action.

Orbital sanders and the grit they utilize are generally far more costly than rotary sanders. However, we believe that their efficiency and versatility are well worth the increased cost.

Personal recommendation

  • If you ever need a versatile tool for grinding a range of materials, a rotary sander is a way to go.
  • If you need available equipment that can be used on several large even surfaces and has high expectations for the polishing quality, an orbit sander is a way to go.


  • Rotary sanders are the less expensive choices, ranging from $25 to several hundred bucks for high-quality instruments. On the other hand, good circles for DIYers cost $50 – $80.
  • Orbital sanders have comparable price stickers. However, there are a lot more varied versions on the marketplace. To illustrate the variations, consider the most common randomized orbits.


In theory, the devices’ domains of use are pretty similar. The rotary sander is ideal for sanding corners, intricate surfaces, and tiny objects.

The orbit on either side is preferable for large surfaces and when a more satisfactory result is desired. The orbital sander also has a much more effective or superior clearance rate and abrasion design.
