How to Use an Orbital Sander

An orbital sander is a versatile power tool that's essential for any DIY enthusiast's toolkit. It's primarily used to smoothen and prepare surfaces, such as wood, plastic, or metal, for painting or varnishing. Below, we'll guide you through an easy-to-follow, step-by-step process of how to use an orbital sander.

How to Use an Orbital Sander: A Comprehensive Guide

How to Use an Orbital Sander

Before we delve into the steps, it's crucial to understand what an orbital sander is. It's a handheld power tool that uses a sanding blade to remove material from surfaces. The blade moves in small orbits, offering high-finish sanding. Unlike belt sanders, orbital sanders are not for heavy material removal but rather for fine finishing.

Step 1: Safety First

Before you begin, remember that safety should always be your priority when dealing with power tools. Always wear safety glasses to protect your eyes from dust and debris. Also, use ear protection because orbital sanders can be loud. Lastly, consider a dust mask or respirator to avoid inhaling the fine dust particles that sanding produces.

Step 2: Choose the Right Sandpaper

The effectiveness of your sanding process heavily depends on the grit of the sandpaper you're using. Lower grit numbers (like 60 or 80) are coarse and remove more material, making them suitable for initial sanding passes or removing paint/varnish. Higher grit numbers (like 220) are finer and help achieve a smooth finish.

Step 3: Attach the Sandpaper

Orbital sanders typically use a hook-and-loop system (similar to Velcro) to attach the sandpaper. Make sure the holes in the sandpaper align with the holes in the sander pad for effective dust collection.

Step 4: Preparing the Workpiece

Ensure the workpiece is secure before you begin sanding. If it's not stationary, it could move around, making it difficult to sand effectively and potentially creating a dangerous situation. Use clamps or a vice to secure the workpiece.

Step 5: Start Sanding

Plug in your sander and press the power button. Allow it to reach full speed before making contact with the surface. Hold the sander with both hands for better control and apply light pressure. Let the sander do the work; forced pressure is not necessary and can lead to uneven results.

Step 6: Sanding Technique

Move the sander in a slow, controlled motion. Remember, the goal is to remove a thin layer of material, not to dig into the surface. For best results, sand along the grain of the wood, not against it. Periodically lift the sander to avoid creating depressions.

Step 7: Progressively Finer Grits

Start with a coarse sandpaper and work your way up to finer grits. Each pass should remove the scratches from the previous grit. Vacuum or wipe down the surface between each grit change to remove dust that could cause scratches.

Step 8: Finishing Up

Once you're done sanding, turn off the sander and allow it to stop completely before setting it down. Clean the surface thoroughly to remove all dust before applying any finish.

Step 9: Maintenance

Proper maintenance extends the life of your sander. Regularly clean the dust collection bag or replace the dust filters. Also, check the sanding pad for wear and tear and replace it if necessary.

It is important to understand and respect the potential hazards when using power tools such as an orbital sander. By using this tool, you agree to and understand the following safety guidelines:

  • Read and Understand the Manual: Before operating the orbital sander, be sure to read and comprehend the manufacturer's instructions and safety guidelines provided in the manual.
  • Personal Protective Equipment (PPE): It is necessary to wear appropriate PPE, including safety glasses, a dust mask or respirator, and hearing protection. Loose clothing, jewelry, or long hair can become entangled in the machine, so ensure they are secured before use.
  • Inspect the Tool: Before use, always inspect the sander for any visible damage or wear. Do not use if there are loose parts or if the tool appears damaged.
  • Proper Handling: Always hold the sander firmly with both hands. Avoid applying excessive pressure as it can cause loss of control or damage to the workpiece or tool.
  • Work Area: Ensure that the work area is clean, well-lit, and free from any potential hazards. Keep bystanders, particularly children, away from the operating area.
  • Dust Management: Sanding can produce a lot of dust, which can be harmful if inhaled. Use a sander with a dust collector or ensure proper ventilation in your work area.
  • Disconnect Power: Always disconnect the tool from the power supply when making adjustments, changing accessories, or when the tool is not in use.
  • Storage: After use, clean the tool and store it in a secure location out of the reach of children.


An orbital sander is an excellent tool for achieving smooth, professional-looking finishes on your DIY projects. By following these steps, you can safely and effectively use an orbital sander. Always remember: the key to a great finish is patience and progression through grits. Happy sanding!
