Nothing sucks a tool up in the spindle like a collet. I think Er 32 collets systems are great, but here I think simple is better for value for machining not tool size range clamping. Lyndex , Vertex and many others are reasonably priced for quality. Five might cost what a set or even a little more. The cutter will have a better chance to do it s duty. What you may spend on your collets you more than save in your cutters. Some of my general machining end mills have hours on them and still in good shape. Theres a sweet spot. Not just speeds and feeds cutters like. Whatever you do on your machine know what your doing. There s enough info out there to educate yourself at this point so you shouldn t think your going to crash a tool. Keep it simple if you have to but know what your doing.
