Frequently asked questions
What is the difference between a random orbit sander and a palm sander?
A random orbit sander uses a circular pad that moves in an elliptical pattern, preventing swirl marks and allowing for both aggressive and fine sanding. A palm sander typically uses a quarter sheet of sandpaper and moves in a straight back-and-forth motion, which can leave swirl marks if not used carefully. Palm sanders are better for tight spaces and detail work.
How do I choose the right grit sandpaper?
Start with a coarse grit (60-80) for heavy material removal, then progress to medium (100-150), and finish with fine (180-220) for a smooth surface. For between coats, use very fine grits (320+). Always match the grit to the task to avoid unnecessary sanding.
Can I use a sander on drywall?
Yes, but you need a sander with a dust collection system that can handle fine drywall dust, and you should use a vacuum attachment. Many corded random orbit sanders work well for drywall, but a dedicated drywall sander with a pole is better for large areas.
Is it worth buying a cordless sander?
If you already own batteries from a platform like DeWalt or Milwaukee, a cordless sander adds convenience without extra cost. Cordless sanders are great for remote locations, but for heavy, continuous use, a corded sander provides consistent power and no downtime for charging.
What is the best way to prevent swirl marks?
Use a random orbit sander instead of a palm sander, and always sand in a consistent motion with light pressure. Keep the sander moving and avoid dwelling in one spot. Use fine grits for finishing and ensure the sandpaper is clean.
How often should I replace the sanding pad?
The sanding pad (hook-and-loop or PSA) wears out over time, especially if you apply too much pressure. Replace it when the adhesive or hooks lose effectiveness, typically every few months with regular use. Always use a pad that fits your sander model.
Can I use a sander for polishing?
Yes, with the correct attachments. You can attach a foam pad and use polishing compounds with a random orbit sander to polish car paint or other surfaces. Ensure the sander has variable speed so you can set it to a low speed for polishing.
What safety gear should I use when sanding?
Always wear safety glasses to protect your eyes from dust and debris. A dust mask or respirator is essential, especially when sanding materials like wood that produce fine particles. Ear protection is recommended for prolonged use due to noise.
Why is my sander not removing material quickly?
Check that you are using the correct grit for the task. Coarse grits remove more material. Also, ensure the sandpaper is not clogged and that you are applying moderate pressure. If the sander is cordless, the battery may be low, reducing power.
What does OPM stand for?
OPM stands for Orbits Per Minute, which measures how fast the sanding pad oscillates. Higher OPM generally means faster sanding, but you may need to adjust speed for different materials to avoid burning or leaving marks.
The bottom line
For most users, the DeWalt 20V MAX Random Orbit Sander is the best replacement, offering a balance of power, comfort, and cordless freedom. If you prefer corded and want to save money, the Bosch ROS20VSC is a reliable choice. For professional heavy-duty work, the Milwaukee M18 is worth the investment. Choose the DeWalt for its overall performance and ergonomics.
