Supposedly these folks have everything S
auter Shop I've looked, but never ordered, so no clue about speed, or service, just they show a lot of collets.
I'm with Nathan. I absolutely hated the collet with Bosch 1617EVSPK So I replaced it with a Muscle Chuck, cost a bit more, but it's the best collet I have ever used. Use that router all the time now.
I do NOT have one, but there is also a lower priced chuck company called
Eliminator Chuck. I've heard good things about them, and if I ever got another router that I disliked the chuck, I would try one.
Porter Cable is a once fabled company that some duds made into a household level tool line, and they have become junk. Sad how these things happen.
Best of luck getting something that will work for you.
