So it looks like my gears that I am cutting on my DIY mill are becoming more popular and I need to find ways to machine quicker / better. Currently the bane of my life with cutting gears is the changing of bits and that I am using a Kress with not the best runout values (and not enough speed control).

Please suggest me something that is decent, not too big but still powerful enough (I mainly cut plastics and brass) - but that has the ability to have 4-5 bits assigned that can be automatically changed and autoleveled ready for cutting without my interaction needed ...

Thanks
