What's the Difference Between a Polisher and an Angle Grinder with a Polishing Pad?
Asked by CraftyPanda93
I'm wondering about the actual differences between a polisher and an angle grinder that has a polishing pad. They seem so similar, especially since I've been hand polishing and want to switch to tools. What are the key differences I should be aware of?

Right! Plus, a lot of polishers come with variable speed settings, something you won't find on many standard angle grinders. Also, polishers might have attachments for water and safety features like GFCI, which adds another layer of safety while you're working.

The main difference lies in their speed and pad size. For instance, polishers typically run at around 2,000 RPM, while angle grinders can go up to 9,000 RPM. That much speed can easily burn your finish, so you definitely want to be careful! Generally, polishers have larger pads, like 7 or 9 inches, while grinders usually have 4 to 5 inch pads. It's all about that control!
HandyAndy77: Exactly, the slower speed is a game-changer for polishing. It really makes a difference!
BobbyBuilder88: And don’t forget about the size variations in angle grinders; they can have bigger pads too!

Another key point is that many polishers feature random orbit action, meaning the backing plate rotates in a circular motion while also spinning. This helps distribute pressure evenly, which is beneficial for a smooth finish. Just remember, too much speed can ruin your work!
