Type 3 Musclechuck, new/never used
I purchased this chuck for my DeWalt 621 plunge router but found that the overall diameter, including the set screw is too large for my bowl bits. I've kept it around thinking I might one day use it but so far not. So, it's available for 50$. This is just the chuck, I do not have either the 1/4" collet or the Allen wrench for this one. Interested buyers should check the Musclechuck web site for compatibility. If you're interested please reply by PM. I'll deliver it within 100 miles of Portland, Oregon for the price of a coffee and a shop tour.
This is not a negative on the Musclechuck. I am very pleased with the one I have in my router table.
