die grinder?

[JFatch1890]

I read a few threads but not the answers i need. Its pretty simple.My compressor doesn't push 90 pounds content witch most air die grinders call for.Should i be safe and just spend the extra money for an electric and who has used both and can let me know what they preferred.

Thanks

Electric die grinders are very powerful, but have a big downside of being cumbersome to work with. You will also need a speed control (Harbor Freight Tools - Quality Tools at the Lowest Prices), as the running speed is greater than many bits can take. Eraser wheels explode, 1/4" shanks bend, not good times.

The electric grinders also get very hot when you are doing a lot of heavy porting on cast iron. I prefer to use an air grinder because they are less cumbersome, and you just have better control all around including speed.

Air all the way. If you got 80 psi. you got enough. Although if your tank is small your compressor might be running alot cause they use alot of air.

It's the CFM, besides the pressure. A nice Harbor Freight grinder is a lot less than twenty bucks. Take the bet. It'll probably work fine, and especially for a home shop where you aren't grinding heads for a living.

I love my Harbor Freight Electric Die Grinder. Ported many things with it and you don't need to worry about your compressor capacity.

Nice and Harbor Freight in the same sentence what a joke..

Go with air. My compressor can't keep up and maintain a constant pressure either, but I manage.

Yeah my compressor may push 70 to 80 constant.Even so i run tons of tools off of it with no problems other then being a little slower id just thought id get opinions.I'm just going to pick up a cheap one cause I'm only porting like 4 things then its probably going to sit on a shelf and maybe be used once ever 4 months to a year.But thanks for the input everyone.
