want advice on buying an orbital sander/ polisher Sign In

Just doing my own vehicle, not for professional use. Would it be essential to have variable speeds? If only one speed, how many rpm is good? I read that too high rpm burns the original paint off. Looking for something cheap-ish. Can I spend $40 and get something decent? thanks

Your key word was NOT for professional use. Now to know jus what you expect for results is a combo of your skills and the tools you choose not so different than anything.


The finest finish work I always sent out so please understand I work/worked WITH the auto body and finish trade not the final spray finish it's own art as much as a trade.


I call what you are after the nick name D/A for dual action orbital sander. You could spend $40 on just the right sandpaper never mind the device(s) you chose - none of this is cheap or that easy.
YOU need to choose but know what to expect so I suggest you just visit a body shop for some suggestions for what you want for results if you pay for some time for hands on showing you some equipment. Body parts + paint suppliers will or should have products and or some tools all should be higher end pricey stuff down to possible for one time use Harbor Freight type places AYOR and ready to return what you buy as not acceptable.


Have to know if you want air power or electric! Takes lots of air to power continuous use tools.


$40 isn't really possible IMO for the worst possible work not enough.


This is an entire trade of training, skills, tools and the place to do it so find out what you'll need in person suggested. Don't forget things like goggles, wipes and thinners, costs for sanding discs (assorted) and so on adds up a lot. If nothing else look at the cost of pro quality masking tape now you'll get the idea,

Thanks for the reply. Definitely electric... I've been checking out shops to buy one and they do seem expensive.. You get what you pay for,,, obviously. Could you comment my question about speeds?

Easy - the more capable to tools the better but said it doesn't end there you need to know how to use it.
I can't know what damage or problem you are fixing and what results are acceptable to you is why I suggested just someone in the trade to be able to see the damage and should be able to say quickly what it would take to get to what.


The $40 bucks stands. You'll lose that in cost of tape and sandpaper never mind a sander.


Again - not to be discouraging just realistic. I've spent that much doing a nice job painting a BBQ grille with a brush!

I think you are confused with the word "orbital" vs "circular".

There are no speed choices with an orbital machine, nor is there any risk of paint damage. It is commonly referred to as a "polisher" as opposed to a circular buffer.

I think what you are referring to are the differences between an electric polisher and a grinder when is comes to speed. The tools appear the same but the RPMs are totally different. Yes, a circular polisher can and will damage paint if you don't know what you are doing and I would strongly advise you against using one.

Never attempt to use a grinder in place of a buffer.

This is a buffer




This is an orbital polisher
