How to choose a random orbital sander
The right sander makes surface preparation faster and leaves a better finish. Your choice depends on the scale of your projects, the materials you work with, and your workspace. For most indoor DIY jobs, a 5-inch model strikes a good balance between power and maneuverability.
Dust collection is critical for a clean workspace and your health, especially when sanding old paint that may contain lead. Always follow safety guidelines from the EPA and wear appropriate respiratory protection. Systems range from simple bags to cyclonic canisters or connections for a shop vacuum. A good dust system also keeps the sanding surface clean for a smoother result.
What to look for
- Power and Speed: Motor amperage and orbits per minute (OPM) indicate performance. Variable speed control lets you match the sander to the material.
- Dust Management: Look for effective collection systems. Canisters are easy to empty, while vacuum hookups offer the cleanest operation.
- Ergonomics and Vibration: Features like rubber grips, counterweights, and a balanced design reduce fatigue, allowing for longer, more comfortable use.
- Disc Attachment: A hook-and-loop (Velcro-style) pad is the standard for quick, tool-free sandpaper changes.
- Kit Contents: Check what’s included. Some sanders come with a variety of sanding discs, a carrying case, or dust collection accessories, offering better immediate value.
Finally, consider the warranty as an indicator of the manufacturer’s confidence in the tool’s durability. For more information on using these tools safely and effectively, explore our other guides in the Power Tools category.
FAQ
What is the difference between an orbital sander and a random orbital sander?
A standard orbital or “palm” sander moves in small, consistent circles, which can sometimes leave visible swirl marks on the finished surface. A random orbital sander combines this orbiting motion with a simultaneous spin, creating a random pattern that typically eliminates swirls and results in a smoother finish, making it a more versatile choice for fine woodworking and finishing.
Can I use my random orbital sander for polishing?
Yes, many random orbital sanders can be used for polishing when equipped with a soft buffing pad and the appropriate polish or wax. Some models, like the Bosch GET75-6N listed above, are explicitly marketed as sander/polishers. Always ensure the sander has a variable speed control, as polishing requires lower speeds than aggressive sanding. Follow the manufacturer’s instructions for attachments and recommended speeds.
How important is dust collection?
Extremely important. Effective dust collection keeps your work area cleaner, improves visibility, and most importantly, protects your health. Inhaling fine dust from wood, drywall, or old paint can be harmful. Always use the sander’s dust collection system, whether it’s a bag, canister, or vacuum hookup. For extensive work, especially in enclosed spaces, also use a respirator approved for fine particles. Learn more about respiratory protection from OSHA.
What grit sandpaper should I start with?
The starting grit depends on the condition of your material. For rough wood with deep scratches or old paint removal, begin with a coarse grit (like 80). For smoothing surfaces between coats of paint or finish, use a fine grit (like 220). Always progress through grits sequentially (e.g., 80, 120, 180, 220) for the best results, sanding just until the scratches from the previous grit are removed. Our buying guide covers this in more detail.
