As you start onto the part, the spindle pushes up from the tool pressure and as you come off of the part, the spindle drops down and bounces causing chattering.

With tooling, you definitely get what you pay for. The cheap endmills and drills are not made from good steel.
I agree with this. But I don’t think Frank will be doing production and maybe get by with middle of the road tooling. If MSC is where you are going, the accupro stuff is kind of ok. It’s no OSG brand good but will work for a tool than maybe you won’t use again.
Do not skimp on taps. OSG, emuge are best IMO.
If you are going with carbide end mills, you have to keep the chips evacuated. You start cutting old chips in a groove they will chip the edge.
Use the feed and speed formula and you will be ok.
