Thinking of grabbing one. Im a teal colour tool chap but the price difference is over double to go from 6mm to 8mm to get the use of 1/4" burrs etc. is it worth it is the question? or are there other brands worth considering? (NOT Red ones)
Did you mean 6mm, 8mm or 1/4" because all three are available....
Don't know about Makita ones, but the air die grinders I have usually come with a 1/4" and 6mm collet to allow you to use either.
Often its the same machine but you can just buy whatever collet you need. They usually aren't that cheap though.
