The Differences Between Angle Grinders and Bench Grinders

Angle grinders and bench grinders are both popular choices for grinding, sanding, and polishing various materials. However, while they share some similarities, they each have unique characteristics that make them better suited for certain tasks. In this article, well break down the differences between angle grinders and bench grinders to help you make an informed choice.

What is an Angle Grinder?

An angle grinder is a handheld power tool that uses a rotating disc with abrasive edges to grind, cut, sand, and polish various materials, including metal, concrete, tile, and masonry. It is also popularly known as a side grinder or disc grinder.

Angle grinders come in various sizes and power ratings, ranging from small 4-inch angle grinders to heavy-duty 9-inch angle grinders. They also have different disc attachments, including diamond discs, abrasive discs, and wire cup brushes, making them versatile tools for a range of applications.

What is a Bench Grinder?

A bench grinder, on the other hand, is a stationary power tool that uses two grinding wheels, one abrasive and one finer. It is mounted on a bench or table and is not portable. Bench grinders are used mainly for sharpening tools, shaping metals, and removing rust or paint from surfaces.

Bench grinders come in different sizes and wheel diameters, ranging from small 6-inch bench grinders to large 10-inch bench grinders. They also have different grits and types of wheels, including coarse aluminum oxide wheels, fine diamond plate wheels, and polishing wheels.

The Differences Between Angle Grinders and Bench Grinders

1. Portability: Angle grinders are portable and can be used anywhere, making them ideal for remote job sites or DIY projects. However, bench grinders are stationary and can only be used in a workshop or garage.

2. Power: Angle grinders are more powerful than bench grinders, with some models having power ratings of up to 15 amps. Bench grinders, on the other hand, typically have power ratings of less than 5 amps.

3. Size: Angle grinders come in different sizes, from small 4-inch models to heavy-duty 9-inch models. Bench grinders, on the other hand, are generally larger, with wheel diameters ranging from 6 to 10 inches.

4. Precision: Bench grinders are more precise than angle grinders due to their stationary position and dual wheels. They are ideal for shaping and sharpening tools with precise angles and edges. Angle grinders, on the other hand, are more suitable for rough grinding and cutting tasks.

5. Safety: Angle grinders are more dangerous than bench grinders due to their high speeds and rotating discs. They pose a risk of kickback, which can cause serious injury. Bench grinders, on the other hand, are more stable and can be used with a range of safety features, such as eye shields and tool rests.

Which is the Right Grinder for You?

If youre looking for a versatile power tool that can handle a range of tasks, an angle grinder may be the right choice for you. They are portable, powerful, and have a range of disc attachments for different applications.

However, if youre looking for a tool specifically for sharpening tools or shaping metals, a bench grinder is the way to go. They are more precise, stable, and have dual wheels for different grits and types of grinding.

In conclusion, both angle grinders and bench grinders have their place in the workshop. The right choice depends on what you need the tool for and the features that are most important to you.
