The best woodworking sander depends on surface area, the finish quality you need and how much material must be removed. A random-orbit sander is the usual all-round choice, but a larger pad, finish sander or detail sander can make more sense for specific work.
Random-Orbit vs Orbital Finish Sander
| Type | Best use | Main trade-off |
|---|---|---|
| 5-inch random-orbit | General furniture and panel work | Strong all-round balance. |
| 6-inch random-orbit | Larger surfaces and faster coverage | Larger and less nimble on small parts. |
| Sheet / finish sander | Light finish sanding | Less aggressive material removal. |
| Detail sander | Corners and small areas | Slow on large surfaces. |
Which Size Is Best?
A 5-inch random-orbit sander is the most versatile starting point for many home woodworkers. A 6-inch machine covers large panels faster. For small parts and tight areas, compact tools are easier to control.
Choosing Sandpaper Grit
Move through grits gradually enough that each step removes the scratches from the previous one. The correct starting grit depends on the surface condition. Avoid starting coarser than necessary because deep scratches take longer to remove later.
Dust Collection Matters
Good extraction improves visibility and helps abrasive discs cut consistently. Use the sander’s dust bag or connect compatible extraction when possible, and follow appropriate dust-control practices for the material you are sanding.
Frequently Asked Questions
Is a random-orbit sander good for woodworking?
Yes. It is one of the most versatile powered sanders for furniture, panels and general surface preparation.
Should I buy a 5-inch or 6-inch sander?
Choose 5-inch for versatility and compact handling; choose 6-inch when larger surfaces and faster coverage dominate your work.
Can an orbital sander remove a lot of material?
It can remove finish and surface defects, but heavy stock removal is usually better handled by more appropriate cutting or milling operations.
