Precision R8 ER32 7/16 Collet Chuck Holder CNC Milling Tool With Wrench
very good finish. no burrs or chips present. well packed with light oil.
It is a very nice looking chuck. No rust or mechanical damages. Runout of internal taper socket is about .008". External R8 taper is about .060" too big in diameter, angle may not be correct. The slot is milled off center, but this does not affect the operation. The spanner wrench is OK, no complaints here. I wish they would include a 35 mm wrench for the flats, it is non-standard and a big adjustable wrench is just too wide for that. Overall it is a very good deal for the money, in regards to quality
This is the second R8 ER32 collect chuck I have had and both are unusable. On the first one, the inside bore had a run out of .004" and the second one was about the same but on the second one the 7/16 internal thread was not tapped parallel to the shank so the drawbar was very tight and this should be a nice easy fit. I don't normally leave negative feedback but because I have had two and they are both really bad I think it is justified as neither are not fit for purpose.
Well built part so far. A little sharp on some edges so be sure to take a stone to them in order to not get cut
great deal
