This lot contains two Hardinge Brand 5C collet stops. Note: these are for 5C collets, both are made by Hardinge. One stop is the conventional stop that uses the internal thread at the rear of the collet. The spindle is new, and has not been altered. The other stop is and expanding stop for when your collet does not have the required internal threads. This collet is in fine condition, the stop spindle may work for you, or you may have to make, or alter this stop. (this is of course very common when using collet stops) Condition is "Used". Shipped with USPS flat rate priority mail
