Dremel or a Die Grinder?
Discussion
My Dremel has finally expired (B&Q Own brand) so I am looking to replace it.
Given that I will be using it to do some cylinder head porting some people have mentioned a die grinder would be a better bet.
What is the difference between the two? Are the bits interchangeable and is it a case that a die grinder just has much more torque? I am excluding air powered die grinders for this as I don't really have the space for a decent compressor.

Die grinder has more power by at least factor of 2.
The collet size on the Dremel's are usually 1/8" whereas die grinders are 1/4"; you can sleeve down but not up in size (ie die grinder works).
I have a Bosch POF900 router which you can take the frame off... and turn into a die grinder. Cheap and effective.. then go to an industrial tools supplier and buy a "Tungsten Carbide Burr" for serious metal removal. The stones are for low rates of removal. Note that without speed control the die grinder is bad for taking a bite and bouncing around a hole with pretty dangereous and unpredictable results to hold it very firm and start slow in speed and/or cutting rates/loads.
The cheapo air powered ones from Machine Mart etc are OK but have less power than the Router above.. good for portable power with air tank or small access.. and are variable speed so can be controlled.
Also have a real Dremel which really has few uses unless into jewellery etc.. (that I found!)
