Looking for advise on which micro motor controller to choose for deburring of small parts (mostly 1/2" dia X 2-1/2" long range with lots of details). I'm currently using a dremel with flex shaft for rotary work and a loud pneumatic "profiler" (UTR-30 link). We have some spending money and think updating our deburring tools to be less tedious would we a great place to spend it. I'm looking at an NSK Emax EVOlution or Espert500 because NSK has a great reputation and many accessories for these tools. Any advise on which to go with and if I should get the "compact" vs the "torque" hand pieces and also ring type vs lever type rotary attachment. I also want to get the mini-luster attachment to replace the pneumatic profiler I use. Is the mini-luster nice to use and easy to do fine detailed filing? Again, any advise on brands, handpieces, accessories, etc. would be greatly appreciated. Thanks!
