Can you use an Angle Grinder as a Sander?

An angle grinder can be used as a sanding disc for a grinder but there are some important factors you need to consider before making the switch. In this blog post, we’ll take a look at what an angle grinder and a sander look like and how it works, and we’ll also discuss the pros and cons of using an angle grinder as a sander. By the end of this post, you’ll have a better idea of whether or not an angle grinder is a right tool for sanding disc for grinder.

What is a Sander?

A sander is an electrical or mechanical device used to smooth materials by abrasion. Abrasive materials like sandpaper are attached to the surface of the disc sander itself.

As their name suggests, Sanders works with a sandpaper belt sander or sandpaper pads.

While there is a wide range of grades available for sandpaper belts and pads, sander attachments are far more limited than angle grinder disc types.

What is an Angle Grinder?

An angle grinder (or side grinder), also known as a side cutter, is essentially a handheld power tool whose main function is to grind down relatively large surfaces at low speeds. Angle grinders typically have a wheel with an abrasive material to cut or polish surfaces that are roughly larger than 10 inches in diameter.

How to use an Angle Grinder as a Sander?

An angle grinder is a type of tool that is used for grinding and cutting excess material. It usually has an output between 5 and 11 amps and can come with either a detachable side handle or a fixed front grip.

Steps to use the Angle Grinder as a Sander:

1) Adjust the head so that it is at a 90ΒΊ angle with the surface of the material.

2) Fit an abrasive flap disc to the grinder and secure it using both sides of the clamping mechanism.

3) Press down on the disc lightly, press in, and pull back toward yourself in one fluid motion while keeping your arms slightly outstretched and locked.

4) Change out the abrasive disc with a new one after every 40 seconds of use.

Sander vs Angle Grinder : Which is preferred?

Though angle grinders are good versatile tools to have around for all types of projects, you may not want one as your primary sander. Because sanders have different speeds and attachments, they’re better suited for lighter jobs that don’t require the heavy-duty power of an angle grinder. Depending on what you’re working on, you may want to consider using other powerful tools like belt sanders (another handheld tool) or orbital sanders (which are stationary).

Difference between Sander and Grinder:

Following are the differences between angle grinders and sanders.

  • Sander is used to smooth materials like wood, plastic, and metals. An angle grinder is used to cut correct surfaces like bricks, stone, tiles, and strip metals.
  • Sander has a very low speed (about 10-14000 RPM), whereas the angle grinder can rotate at 6000 – 20000 RPM depending on the type of the product. Angle grinders can break or burn the material being worked on when the speed is too high.
  • An angle grinder weighs about 1kg per piece, whereas a sander typically weighs hundreds of grams to a few kilograms per piece depending on the size and type of the product.
  • Sander can have any kind of abrasive resistance, while angle grinders typically have diamond or silicon carbide.
  • Sander has wheels that are typically 6 inches in diameter, whereas an angle grinder usually goes up to 7 inches in the smaller models and more than 10 inches in the bigger models. Larger wheels allow for faster material removal while having a smaller wheel allows better control of your work piece.

Angle Grinder as a Sander: Pros & Cons

There are some benefits to using an angle grinder, especially if you’re working with larger projects that require standing for an extended period of time, but there are also some important factors to consider before making the switch.


  • Angle grinders are powerful enough to sand through large surfaces quickly, meaning you can get straight to work on your project. Since angle grinders are handheld tools, they’re also easy to carry around the work area.
  • Angle grinders are relatively inexpensive – you can find them at most hardware or home improvement stores for between $15 and $40.


  • Angle grinder sanding cutting discs only last for about an hour before they need to be changed, which means that if you’re working large project, you’ll likely need to make plenty of trips back and forth to the hardware store.
  • Angle grinders can be dangerous – if not used safely, they can cause severe injuries. Make sure that your angle grinder is attached securely before turning it on; never wear loose clothing or jewelry (like necklaces) while using an angle grinder, as they can easily get caught in the rotating disc and cause serious injury.


There are some important considerations to take into account before using an angle grinder as a sanding disc for a grinder. We’ve outlined the key differences between sanders and grinders when it is appropriate to use each type of tool using the right safety materials.
