I'm asking because i've had this happen twice in 2 days and it's pissing me off.
Problem: I've had the guide bushing get loose during use...i'm routing out some deep mortises w/a 1/2" spiral upcutting bit.
I've tightened this down with pliers and it still came loose. I'm using a set sold my Milwaukee but do i just need a better set? Anyone else have this issue?
