I would feel 3K is a bit slow for little carbide
drills.  I have one of them there Sakai MDH-1
drill presses.  It does 12K and I feel like I
want a little more when I am doing 0.5mm holes.

The Sakai is a nice little unit and I would
recomended it whole heartedly to the original
poster if it fell into the same ball park price.



I wonder if anyone that hangs around in the LRK
group has thought of making his own brushless DC
high speed spindle.........
