End mills / Drill bits for aluminium

[JAZZCNC]

Anyway, JAZZCNC, where did you buy your end mills, and do you have any suggestion for good price-performance wise end mills for aluminium?
I guess I will need 6,8,10 mm 2 flute end mills for pocketing and something like 8mm 3-4 flute for inside-hole finish.

I buy most of my tooling from cutwell tools but I'll buy from Ebay when I see quality cutters come along at right price. Buying cheap cutters is false economy in long run because if they snap the potential for wrecking the job is high and at very best time is wasted. On some jobs this can wreck expensive material and you can bet your last penny the bastard will snap 10mins from end of 6hr job.!!
Only time I'll use cheap cutters is if they are so cheap I can afford to throw away after each job or I have lots of little jobs so can keep an eye how it's working.!

Like Jonathan says and you have seen you can tweak the VFD to give more Torque but your messing with fire and can easily fry something and will certainly shorten it's life so is it really worth the trouble.? If you need torque which you really do for drilling then really you need to look at a differant setup for the spindle. Something like Collet spindle in a housing connected to a normal motor 2 pole 3 phase motor via belt drive and gearing 3:1ratio to 1000rpm would give you the torque required.
If done correctly you could design a back plate system so they could be swapped over for when you require milling.? This is really the only way you'll get reliable drilling without getting silly on price for the correct spindle.
