Guide to Sanders: Finding the Right Type

Different sanders do different things. Using the wrong one wastes time and produces poor results. Here's which sander to use when.

Sander Types

Random Orbital Sanders

The all-rounder. The pad spins AND orbits randomly, preventing swirl marks. Best for:

• General sanding of flat surfaces
• Finishing work
• Removing paint and finishes
• Preparing surfaces for coating

If you buy one sander, make it a random orbital. Our random orbital sanders include quality options.

Orbital Sanders (Sheet Sanders)

Simpler vibrating motion. Square or rectangular pad uses standard sandpaper sheets. Good for:

• Fine finishing
• Getting into corners (square pad)
• Light sanding between coats
• Budget-conscious users

Less aggressive than random orbital, slower material removal.

Belt Sanders

Continuous belt of abrasive over two drums. Aggressive material removal. Best for:

• Levelling uneven surfaces
• Removing material quickly
• Shaping and heavy sanding
• Floor sanding (large models)

Check our belt sander range. Powerful but easy to damage work if used carelessly.

Detail Sanders

Small triangular or finger-shaped pad. Reaches places other sanders can't:

• Tight corners
• Mouldings and profiles
• Furniture restoration
• Window frames

Browse detail and multi sanders.

Disc Sanders (Bench)

Stationary tool, work moves against the disc. For:

• Shaping small pieces
• End grain sanding
• Accurate angles

File Sanders

Narrow belt for getting into tight spaces. Useful for metalwork and detailed areas.

Choosing the Right Grit

Abrasive grits progress from coarse to fine:

• 40-60 grit - Heavy material removal, shaping
• 80-100 grit - General sanding, removing old finishes
• 120-150 grit - Preparation for finishing
• 180-220 grit - Final sanding before finish
• 240+ grit - Between coats, fine finishing

Work through grits progressively. Jumping from 60 to 180 leaves deep scratches visible through finish.

Dust Extraction

Sanders produce lots of dust. Important considerations:

• Dust bag/collection on the sander (basic)
• Connection to vacuum (better)
• Proper extraction system (best for regular use)

Wood dust is a health hazard. Don't breathe it.

Features to Consider

• Variable speed - More control, essential for some materials
• Dust collection - Quality of extraction
• Pad brake - Stops pad when lifted (random orbitals)
• Soft start - Prevents jump when starting
• Ergonomics - You'll hold this for extended periods

Which to Buy First?

1. Random orbital sander - the universal choice
2. Detail sander - if you do furniture or detailed work
3. Belt sander - for heavy removal work
