| Feature | 5-Inch Sanders | 6-Inch Sanders |
|---|---|---|
| Sanding Area | 19.6 sq inches | 28.3 sq inches (44% larger) |
| Best For | General purpose, furniture, cabinets | Large flat surfaces, production work |
| Maneuverability | Excellent - works in tight spaces | Limited - harder in corners |
| Weight | 2.5-3.5 lbs typically | 2.5-4.0 lbs typically |
| Sandpaper Cost | Lower - more widely available | Higher - specialty sizes |
| Sandpaper Selection | Huge variety from all brands | Good but more limited options |
| Speed (Large Surfaces) | Standard | 44% faster coverage |
| Price Range | $40-400 | $150-500 |
| Recommendation | Best for most users | Best for pros with large surfaces |
Our Recommendation
Start with a 5-inch sander. It handles 95% of sanding tasks effectively and sandpaper is cheaper and more readily available. Add a 6-inch sander later if you frequently work on large surfaces like tabletops, doors, or panel work where the 44% larger coverage area saves significant time.
Key Features to Consider
Variable Speed Control
Variable speed lets you adjust the sander's aggressiveness for different tasks. Lower speeds (4,000-8,000 OPM) are ideal for:
- Sanding veneer without burning through
- Delicate finish work on softwoods
- Scuffing between finish coats
- Working with heat-sensitive materials
Higher speeds (10,000-12,000 OPM) work best for:
- Aggressive stock removal with coarse grits
- Sanding hardwoods
- Leveling joints and patches
- General-purpose sanding
Dust Collection
Good dust collection keeps your workspace clean and protects your lungs. There are three main approaches:
- Dust bags: Basic collection, needs frequent emptying. Works for quick jobs but not ideal for extended sanding.
- Dust canisters: Better collection with microfilters that trap fine particles. The Bosch ROS20VSC excels here.
- Vacuum connection: Best collection when connected to a shop vacuum or dust extractor. Festool and Mirka lead in this category.
Pad Brake
A pad brake stops the sanding disc from spinning when you lift the sander off the work. This prevents accidental scratches when setting the sander down and extends pad life. Most quality sanders include this feature, but budget models may not.
Orbit Size
Orbit size (also called stroke length) affects how aggressively the sander removes material:
- 3/32 inch (2.4mm): Standard orbit size, good balance of removal and finish quality
- 1/8 inch (3.2mm): Larger orbit for faster stock removal (Makita BO5041)
- 5mm: Common on 6-inch professional sanders
Larger orbits remove material faster but may leave more visible scratch patterns. For fine finishing, smaller orbits or lower speeds produce better results.
Ergonomics and Vibration
You'll hold a random orbital sander for extended periods, so comfort matters. Look for:
- Vibration dampening (reduces fatigue and hand-arm vibration syndrome)
- Soft-grip surfaces that don't become slippery with sweat
- Balanced weight distribution
- Multiple grip positions for different tasks
Corded vs Cordless Random Orbital Sanders
| Factor | Corded | Cordless |
|---|---|---|
| Power | Consistent, unlimited | Good but may fade as battery drains |
| Runtime | Unlimited | 30-60 min per battery typically |
| Weight | Lighter (no battery) | Heavier with battery attached |
| Mobility | Limited by cord length | Complete freedom |
| Best For | Shop work, extended sessions | Job sites, outdoor, quick tasks |
| Price (tool only) | $40-400 | $80-250 (battery extra) |
| Total Cost | Tool cost only | Add $100-200 for battery + charger |
When to Go Cordless
Choose cordless if you work on job sites, do outdoor projects, or already own batteries in a compatible system (Milwaukee M18, DeWalt 20V MAX, Makita 18V LXT, Ryobi ONE+). For dedicated shop use with extended sanding sessions, corded remains the better choice for consistent power and lighter weight.

Frequently Asked Questions
What is the best random orbital sander for beginners?
The Bosch ROS20VSC is the best random orbital sander for beginners. It offers excellent value with variable speed control (7,500-12,000 OPM), superior dust collection, and low vibration. The ergonomic design and forgiving nature make it easy to learn proper sanding technique without damaging your workpiece.
Is a 5-inch or 6-inch random orbital sander better?
5-inch sanders are more versatile and better for most users. They're lighter, easier to control, and sandpaper is more affordable and widely available. 6-inch sanders cover 44% more area per pass, making them faster for large flat surfaces like tabletops and doors. Professional cabinet makers often prefer 6-inch models for production work.
What orbit size is best for random orbital sanders?
Most random orbital sanders have a 3/32-inch (2.4mm) orbit, which is ideal for finish sanding. Some aggressive models like the Makita BO5041 feature a larger 1/8-inch (3.2mm) orbit for faster stock removal. Smaller orbits leave finer finishes, while larger orbits remove material faster but may leave more visible scratch patterns.
Are cordless random orbital sanders worth it?
Cordless random orbital sanders are excellent for job site work, outdoor projects, and situations where cord management is difficult. Modern brushless cordless sanders like the Milwaukee 2648-20 perform nearly as well as corded models. However, corded sanders offer unlimited runtime and are typically more powerful, making them better for extended shop use.
How important is variable speed on a random orbital sander?
Variable speed is very important for versatile sanding. Lower speeds (4,000-8,000 OPM) are ideal for delicate work, preventing burn-through on veneer, and sanding between finish coats. Higher speeds (10,000-12,000 OPM) are better for aggressive stock removal with coarse grits. Variable speed also helps control heat buildup when sanding plastics or heat-sensitive materials.
What causes swirl marks with a random orbital sander?
Swirl marks are caused by pressing too hard, using worn sandpaper, skipping grits, or moving the sander too fast. Let the weight of the sander do the work, replace sandpaper frequently, progress through grits systematically (don't skip more than one grit level), and move the sander slowly at about 1 inch per second. Also ensure the pad is spinning freely and not stalled.
How long do random orbital sander pads last?
Hook-and-loop sanding pads typically last 6-12 months with regular use. Signs of wear include sandpaper not sticking properly, torn or flattened hooks, and visible pad damage. Replace the pad when sandpaper starts slipping or not adhering evenly. Quality pads from the original manufacturer last longer than generic replacements.
Is Festool worth the price for random orbital sanders?
Festool sanders are worth the investment for professionals who sand extensively. The ETS 125 REQ-Plus offers exceptional dust extraction (95%+ collection rate with Festool vacuums), extremely low vibration, and a brushless motor with long service life. For occasional DIY use, mid-range options like the Bosch ROS20VSC or DeWalt DWE6423 offer better value. Festool's quality is unmatched, but the price premium is only justified by heavy professional use.
