As the title says the D1-4 x ER 40 collet chuck arrived today, I ordered it Christmas Eve, it arrive Amazon (USPS), late this afternoon. I had to adjust the mounting pins (trial and error), but it all worked out in the end. The runout was very acceptable (for me) and was well below the 3 jaw chuck. The fractional collets I ordered, will be here in about a week and the R8 x ER 40 collet chuck has shipped and should be here by 1/5/21.
