Can You Use An Angle Grinder As A Sander: Most Effective Ways 

Can you use an angle grinder as a sander-is this a general question for many DIY enthusiasts who work predominantly with reclaimed or pallet wood? If you want to remove the excess materials, you have to use a sander as the best equipment for the work. Making the wood well-fit for your next project requires sanding the wood surface to make it smooth. Though an angle grinder might not be the ideal tool for sanding wood, it is one of the best versatile tools that can perform an excellent job in your wood workshop. 

What Are The Key Differences Between Grinders & Sanders?

We can work with sander and grinders for different project surfaces. There is nothing to be confused about between the purposes of these tools as they work differently. They both have different attachments. It becomes challenging to choose between similar options for any home project. Let’s get into the discussion about the differences between grinders and sanders. 


You can find many different grinders available on the market. However, an angle grinder is the most popularly used. It can be with or without a chord and has a rotating disk at the edge of it. You can switch the discs and accommodate different projects like metal, wood, or other materials. It works very well for polishing as well. The versatility of this tool makes it so comfortable to work with too many workers. Grinders contain a handle on the side so that you can hold it while working. Grinders can cut through metal, strip metal, or polish surfaces.  


A Sander is a valuable tool for different kinds of woodworking projects. It has sandpaper to give the surface a smooth finish and remove paint or stain from wood. The belt sander looks belt-shaped and moves between the tool. There are palm sanders or orbit sanders, too, for other different works. Sanders is typically used to sand the excess materials, but grinders have multiple benefits.

Can You Use An Angle Grinder As A Sander For Sanding?

Yes, it is possible to use an angle grinder for sanding. You can turn an angle grinder into a sander by attaching an abrasive flap disc. Then, you can use it for sanding wood, metals, or other things. However, using a grinder has some drawbacks too. It is recommended not to use a grinder to flatten an unsmooth surface. It would be best if you used an angle grinder only to remove excess materials fast and easily. There are two most applicable methods to apply an angle grinder to sand.

Method 1: Using Flap Disc

The first method is to use the flap disc, a sanding disc with some overlapping sections spaced across the disc’s surface. The flap discs can easily and quickly sand large areas within a short time. 

Method 2: Using orbital sander attachment for an angle grinder 

An orbital sander is a perfect device to use for top-down sanding. Turning the angle grinder into an orbital sander is possible with an accurate attachment. The small-sized orbital sander will allow you to do most of your project in a significantly less amount.

How Can You Use An Angle Grinder To Sand?

There are several steps to follow to use an angle grinder to sand.

Step 1: Attaching the flap disc

After having the right flap disc for your project, you must attach it to the angle grinder. A flap disc operates similarly to a grinding disc.

Step 2: Wearing safety protections

Ensure you use the proper safety equipment like masks, gloves, glass, and ear protection. 

Step 3: Matching the angles

It would be best if you switched in the grinder. Apply the flap disc properly to match the angle of the flap disc to the surface. 

Step 4: Leave the disc to work 

Applying too much pressure on the workpiece is prohibited. Too much pressure will tear the flap discs apart. As a result, it will cause gouging, and the burn marks are very stubborn to get rid of. So, always consider giving light pressure on the workpiece and let the disc do its work. While removing the top layer of the workpiece, use back and forth motion. 

Step 5: Finishing sanding

Hopefully, you are successfully done with removing the surplus material with the disc. Now, switch to higher grit flaps and finish the rest of the work.
