Hi everyone

Has anybody used a router bit collet extension yet? I think it sounds like a good idea but worry about it comming loose during operation of the router. I have a ridgid router but with this MCLS extension I can change bits without removing the router and gain more above the table height too.

Any thoughts please?

Jim, if your collet is in good shape the extension should not come loose any sooner than a router bit will. I have run one in my Dewalt 625 for several years and have not had any problems.

I’m quite interested in trying an extension. Just have not overcome the cost and the questions you raise. Thanks for asking the question, it’ll help me out too.

I’ve used the Eliminator chuck extension for several years and really like it. Sure beats wrenchs to change router bits

I have only 1/2 inch bits for my router. I just got a sale catalog from MLCS they have a 1/2 inch extension for 29.95 including the wrench.

I’ve used my MLCS collet extender some (not a lot). Maybe I am over cautious but I go pretty slow with the extension in place. It just seems like the potential is there to over stress the extension. So far I have had no problems.

Note – If you are cleaning out a router bowl, you can (and should) remove most of the material with a forestner bit. The only purpose of the router bit is to clean things up.

thumbs up ! I have been using an extension on a onsrud for years . I swing the overarm out of the way and have a shaper fence setup , adapted for hogging out oval tenons on chair legs . I use a generic freud 1” flute cutter and they were not long enough. No problem with runout.
