Edge Sanders vs. Belt Sanders: Which is Better?

Choosing the right sanding equipment for your workshop depends on the type of work you do. While both edge sanders and belt sanders are designed to smooth surfaces, they serve very different purposes. Understanding their differences is key to choosing the right machine—or combination of machines—for your setup.

What Is an Edge Sander?

An edge sander is designed specifically for sanding the edges of wood panels. It features a long, narrow sanding belt mounted vertically or horizontally, allowing precise control over narrow surfaces. Most models also feature oscillating heads or adjustable tables to support curved workpieces.

Ideal for:

• Cabinet doors and panels

• Shelves

• Solid timber edging

• Internal and external radii

Machines like the Kundig Uniq or Kundig Flash are built for professional workshops, offering accurate edge finishing and high-spec options for lacquered or veneered materials.

What Is a Belt Sander?

The term "belt sander" often refers to wide belt sanders in commercial settings. These machines are designed for sanding large, flat surfaces such as tabletops, cabinet faces, and doors.

They feature wide sanding belts (typically 950–1350 mm), conveyor feed systems, and multiple sanding heads. Machines like the Kundig Premium offer consistent surface sanding at high speed, with options for calibration and fine finishing.

Ideal for:

• Flattening panels

• Preparing surfaces for painting or veneering

• Removing material quickly and evenly

Key Differences

Feature	Edge Sander	Belt Sander (Wide Belt)
Application	Edges, curved shapes, small pieces	Flat panels, wide boards
Surface Area	Narrow contact area	Large sanding surface
Feed System	Manual or semi-automatic	Fully automatic with conveyor
Precision	High for detailed edge work	High for flatness and even finish
Space Requirement	Smaller footprint	Larger machine, needs dust extraction

Which One Should You Choose?

It depends on your workflow. If your business focuses on cabinetry, joinery, or furniture production, you’ll likely need both:

• Use a wide belt sander for large panels

• Use an edge sander for final edge finishing and detailing

For smaller workshops or those just getting started, an edge sander is often the more versatile machine. It can handle a variety of shapes and materials, and it's generally more affordable and compact.

If you’re primarily producing flat panels in high volumes, a belt sander will save considerable time and ensure surface consistency.

Final Thoughts

Edge sanders and belt sanders each have their strengths. One isn’t better than the other—they’re complementary tools. Most professional workshops benefit from having both to cover the full range of sanding tasks.
