While it is possible to use an angle grinder polisher for some aspects of finishing or buffing job. This job is not recommended by any manufacturer that produces polishing tools or accessories for power tools because of the consistent polishing speed and motion of an angle grinder will likely cause damage to sensitive surfaces.

An angle grinder machine can be used as a polisher. However, using a polisher to grind materials does not determine the optimal process for polishing using an angle grinder set to a variable frequency.

Let’s study few Pros and Cons:

PROS:

Angle grinders and sanders work on two different principles. First, an angle grinder is designed to use sandpaper or other abrasive tools, while a sander uses a dry material such as sandpaper to smooth flat surfaces.

In addition to using sandpaper with a common angle grinder, it is possible to use polishing tools. The main disadvantage of using an angle grinder for sanding is the motion when grinding, which could damage the wood or metal surface being worked on.

Sanders are indeed valuable tools to have in your toolbox, but angle grinder tools can accomplish the same task with possibly better results in the long run. Because classic angle grinder is so flexible, you can buy sanding discs that are particularly made for sanding.

Flap discs are angle grinder attachments with a wide variety of applications, including flawless mirror finish on a surface that must be smoothed out. Compared to sanding discs, angle grinders may go much beyond when sanding wood surfaces.

Is it Possible to Buffer with an Angle Grinder?

An angle grinder is not designed for buffing or sharpening surfaces. Instead, the variable speed of an angle grinder can cause damage to sensitive surfaces such as those used in buffing pad.

For example, using an angle grinder as a rotary buffer is possible. Still, it is not recommended by any professional or manufacturer that produces polishing tools or accessories for power tools because of the potential for damage.

Moreover, it would help to operate your bench grinder at a much slower pace than typical to avoid burning your engine. For example, the cooling flow of air ordinarily generated by an angle grinder polisher is reduced significantly at a decreased speed.

Can Steel and Aluminum be Polished with an Angle Grinder?

  • Steel can indeed be polished using an angle grinder, but this should only be done if the surface has previously been rough edges-cut with a cutting disk. Steel polishing is best done with steel wool by hand. However, it can be buffed out using an angle grinder with a dedicated flat disk or flap disk attachment. It is not recommended that you use a wire brush because this may create sparks and have other hazardous results.
  • Aluminum can be polished with an angle grinder, but it is not recommended because this will create a lot of sparks, and the heat generated might warp aluminum. The aluminum polishing process should be done by hand or with special power rotary tools that do not use abrasive material like flap disks.
