I took a chance on this because of the low cost and Amazon's return satisfaction policy. I was pleasantly surprised at the fit, finish and accuracy of the chuck. Fits ER-32 collets perfectly, MT-2 taper is accurate and has less runout than the spindle I am using it with in a Sieg X1 Micromill converted to belt drive. Very satisfied.

Great value. Surprised for the cost. Used for my South Bend 9 tail stock. Interested about run out but can't be checked in tail stock. Impressed so far.

I was very surprised by the accuracy!! You hear so much about some of these being bad, but this one was quite accurate and works well for me.

Shank snapped off in less than 3 months of use. Perhaps if it wasn’t hollow for the draw bar and there was more than .125†of material where the Er32 collet body connects to the shank it would be more rigid. Also was very chattery from the get go. I shouldn’t be surprised considering the price.

Collets snap into clamping ring. Learned this the hard way.

This is so much better than I expected for the price. Machining is great. Threads are great. I put an indicator on the leading edge of the chuck and it was less than .0005 off.
