    Knurled Drive Roller (MIG 135)

    Product Review (submitted on May 17, 2012):

    I received my Knurled Drive Roller and it does not have a set screw. It says in the description to use your original but my original doesn't have one either. What it has is a notched key stock. And the Knurled Drive Roller has no notch so it just spins with no set screw. Just a paper wait for me. :(
