Do mini die grinders have enough power to do standard porting work on the irons? Or should I get a standard one with more power?

The main reaons I want a mini die grinder is because they're easier to be precise with when porting, uses less cfm (less interrupting when my compressor recharges), and its a bit cheaper ($25-30.)

If it matters, I plan on using carbide bits to do the port work.

I've always thought die grinder > Dremel ??

I have a mid-end Dremel but it likes to halt when I really start to grind on some hard stuff. and then makes some nasty rough edges. And from what I've seen, a die grinder just shrugs it off and seems to have so much more power and speed to make smoother ports.

I hate dremels, I've burned out 2 of them.

i didtn have any problems. maybe its the bits that were being used? i know bdc uses only dremels on his porting.

I've always used my dremel and the cheap stones to do my porting. I finish them up with sanding drums and a polishing drum. My latest efforts are in a thread on Nopistons.com, all done with a dremel. I prefer the dremel because it is lighter and easier to control.

Well, I bought the mini die grinder. If it sucks, then no big deal. It was only $20.

Dremel with cut-off disks, a couple stones and sanding drums. It takes a bit longer than an air die grinder, but it's cheap, easier to control, less noise, less costly to operate (small electric motor vs electric air compressor motor) and dare I say less messy?
