Default Need a collet extender

I need a collet extension. I am thinking of buying Router Technologies EX 2080 Xtreme Xtension Professional Router Bit/Collet Extension - https://www.amazon.com/Router-Techno...llet+extension. The advantage is that it can be used with 1/2" and 1/4" shank bits. Does anyone have experience with this? My concern is that the bit is fastened with a hex-screw rather than a threaded nut. The other option I am considering is CMT 796.001.00 Router Collet Chuck Extension for 1/2-Inch Collets, 1/2-Inch Shank with the limitation that it accepts only 1/2" bits. Any guidance will be appreciated.

I have the CMT...
no worries.. no balance/resonation issues that I have found w/ the set screw style...
balance/resonation issues can be detrimental to your router's bearings/field/armature...
use reducing collets to enable for ¼'' shanks...

I have both. First I got the CMT one. I needed an extra 1" due to my table's thickness which I was unable to change. It frightened the heck out of me and due to it's length, the bit would not go below the table.

Then I found the Xtreme XTension. Wow, chalk and cheese. It worked great immediately, no fear, locked it into the router and used a straight bit immediately with a great result. It gave me the extra height I needed and it is transferrable to any 1/2" router. Using 1/4" bits is also no problem. Just shove in the 1/4" thingy with the slot in it's side lined up with where the allen screw goes through to tighten it. Then just tighten away.

I now have above table bit changing, so no need to go diving under the table.

I have read some users have experienced the allen screw breaking or rounding out after a time so they bought stainless steel ones. I got 4 stainless steel ones and replaced mine, keeping the other 3 for future use, nothing like being prepared. Also shiny stainless steel in the shiny extension does look pretty

I have never had a bit come loose and no experience of wobble due to it being out of balance, unlike the CMT one.

Hope this helps.

Just looked at the amazon link you put up. It shows an allen key. Mine came with a T-handled hex key with a ball end. If you get this and it only has the allen key I'd suggest getting a t-handled hex key with the ball end as it does make it easier when the extension is less than an inch above the table.

Hank if you only need a little bit more extension you might consider the Musclechuck. Quick Change Router Chuck - Camless Router Chuck - Dewalt - Porter Cable - Festool - Hitachi - Bosch - Makita - Trend - Freud - Fein - Metabo - Carvewright Members who have replaced their OEM collet with a Musclechuck say it is far superior to the OEM collet, has more holding power, and is quicker to change bits with. Forum members used to get a discount when they bought them.

Thanks for the responses. Stick - I don't see an insert option in the CMT. Is this the kind of reducing collet you mean? RB-100 High Precision Steel Router Collet Reducer 1/4 Overall Dia x 3mm Inner Dia x 1 Inch Long

On the same topic - I see that Amana makes a collet reducer and a reducer bushing. From the pictures, looks like collet reducer is what I need. The right size bushing (1/2 to 1/4) is available through Amazon, the collet reducer is not - adding about $6.50 shipping to a $6.20 item through ToolsToday. More important of course is getting the right item especially on something that has safety implications.

My Hitachi M12V only came with a reducer bushing like the one you linked to for using 1/4" bits. I don't think a 1/4" collet is available for it. I've never had a problem using it. Lee Valley sells quite a few bushings for different size shanks. They sold for C$4.80 last time I bought some.

The problem with the muscle chuck is they aren't interchangeable to every router, so if you change the router in the table you will probably need to buy a new one. Whereas the Xtreme Xtension is just taken from one router and put in another.
