I have a good bit (30 years) of experience in industrial CNC, mainly routers, and all the support items necessary to make them work. I have almost zero in the smaller CNC routers for hobby and light industrial applications. A friend of mine has (t)asked me to help him install and train on new router for his shop.
The vendors I'm familiar with for tooling are not cheap, but they were very good quality. My question is this - while looking for an inexpensive source for ER20 collets I see on Amazon that they can be had for $30 - $50 for a set of 10, 15, 20 collets. Anyone try these? Are they any good at all or would I risk ruining the bearings and/or bits?
Thanks in advance.
