Frequently Asked Questions
What is the difference between an orbital sander and a regular sander?
One key difference between an orbital sander and a regular sander lies in the type of abrasive used. While a regular sander relies on sheets of sandpaper, an orbital sander employs specialized sanding discs for its circular motion. These discs, available in various grits, generally come at a higher cost than conventional sandpaper. This distinction in abrasive materials can impact the overall effectiveness and precision of the sanding process.
Moreover, the circular pattern produced by an orbital sander differs from that of a regular sander. The orbital sander moves in an elliptical or orbital motion, allowing for a more random sanding pattern. This random pattern can result in a smoother finish with reduced swirl marks and scratches compared to the linear or back-and-forth motion of a regular sander. Ultimately, the unique combination of specialized sanding discs and orbital motion sets apart the orbital sander as a distinct and efficient tool for achieving a refined surface.
What is a orbital sander used for?
An orbital sander is a versatile hand-held tool designed to quickly and efficiently create a smooth surface.

Whether you need to restore a piece of furniture or prep a surface for painting, the orbital sander can help you achieve the desired result in a shorter time compared to other methods.
What is the difference between orbital and rotary sander?
The key difference between an orbital and a rotary sander lies in how they operate. While both sanders have a round pad, the rotary sander does not vibrate like the random orbital sander. Instead, the rotary sander’s pad is directly connected to the tool’s motor, allowing it to harness the full power of the motor. This design enables the rotary sander to remove material more aggressively and efficiently, making it a suitable choice for tasks that require heavy-duty sanding or material removal. In contrast, the random orbital sander’s vibrating motion provides a more gentle and controlled sanding action, making it ideal for achieving a smoother, finer finish on surfaces.
What are the disadvantages of orbital sander?
One disadvantage of an orbital sander is its potential to leave behind depressions if not used carefully due to its high abrasive power. When excessive pressure is applied or if the sander remains in one spot for too long, it can result in uneven surfaces and noticeable indentations. Additionally, sanding against the wood grain can cause visible sanding scratches, making it crucial to pay attention to the direction of the wood grains when using this equipment.
Another limitation of orbital sanders is their inability to be used effectively in narrow spaces such as hallways or entryways. Due to their large size and circular motion, these sanders require sufficient space to maneuver and may not effectively reach into tight corners or confined areas. As a result, alternative sanding tools may be required for successfully sanding surfaces in such restricted spaces.
