They are small, yet beefy enought to do some good depths in copper. That is why I suggested that size to Ben. Now if you had the time, and are using CNC you might get away with 1/16 with light cuts. But I wouldnt recomend it, cause the cost could start to stack up.

Hmmm, when all you have is a hammer, everything looks like a nail eh?
Am getting my batch of waterblocks made up with a CNC mill with a 1mm mill bit. Works just fine and not too slow at all.
Requires a very high cutting speed and the coolant injected at a high velocity at the cutter (or so I'm told).
Not that I have any real experience with CNC milling, but the guys I'm using are perhaps the best in the business in my state (Victoria, Australia) and they didn't seem to think it would be any major problem for them when I quizzed them on the difficulty of machining copper with 1mm bits.
