I have an R-8 to ER collet holder. Every time i use a collet i have one "HECK" of a time removing the collet. I am using the wrench to tighten the collet. Making my cuts then using the wrench to remove the locking ring. The collet just sticks there and will not come out. I have to remove it by force...and i mean FORCE.

What is the trick?

You are snapping the collet in the nut before putting it in the arbor, right?

The collet snaps into a groove in the cap. When loosened, the cap self-extracts the collet, freeing the endmill. That's how it's supposed to be used.

spkrman15,
If you haven't been snapping the collet into the nut before tightening it you might want to inspect the nut and collets for damage. The retaining ring will gouge the collet and the ring will break sometimes if not installed properly.

Aw yessss. There is nothing like reading the "instructions" first. :-)
Woodworking routers have been using that style of collet for years.

Lew....you are assuming that instructions came with the kit!

On the good news side. Yup Snaped in the collet, and it works like a charm. That is way easier.

Thanks everyone

Rob :)
