Update:
I got a SMALL batch from the machinist today. He is working on another style of tip tomorrow. I will send these through some testing to see how they work in the field.
The machining tolerances are great. They slide into the centrotec chuck very smooth, but they feel a little tighter than the festool ones. (less runout).
He had to make a fixture to hold the smaller 2" tips, because they don't have much material to hold in the lathe.
I will have a chance to use these in the field tmr. I want to take a couple weeks to make sure the bits hold up in the field.
