Upon further inspection I'll be returning the 5C collet/tool holder. After cleaning the grease off there is .002" clearance between the 5c collet holder and the cast housing. Although the grind looks okay I did not check dimensions. The cast housing ID is very poor. The widths of the spacer, graduated dial and the index plates are not uniform, as much as .005" from low to high spot.

I have been looking for a 5c collet holder for my deckel but i'm not satisfied with the ones i found due to quality.
If someone has any suggestions where to look i really appreciate some guiding.

My issue is that i like to grind 16x16mm square HSS for my deckel FP1 slotting head. (can't use U2/E355 collets for this)
I have done some holders/adapters for smaller HSS spline tools but really like to do the tool in one price for rigidity and precession
