You should find that these ones are the best there is Big_al, and they are made by CMT, ..originally they made them for the DW625 Router, and then Trend started buying them from CMT, now CMT do a replica of the DW625, so produce them under their own Brand name, hence the same item for a lot less! , i actually own 2 of these little babies, (save having to swap them out!!!!)

the link!!! http://www.axminster.co.uk/product-CMT-Router-Collet-Extension-29824.htm

hope this helps!

and if not in stock, try any one that stocks CMT stuff!!!!

I've had rave reports about the Extreme extensions, they are expensive but make bit changing in the router table a lot easier, but at a price.

I've just bought a Trend extension but it's the same price as the Extreme, it has the same locking mechanism as fitted to the DW625 rather than a simple collet as fitted to the CMT, hence the price.

I am perplexed W/S, my CMT collet extensions are identical in engraved shank serial/part number to my OFFICIAL DEWALT one, and also my TREND version! (only trend has an 8MM adaptor at the end!) the only real difference i can find is that the CMT has a two flats nut which still clips to the multi split collet, whilst the DW/Trend have a full multi flat nut!!!

I use the xtreme xtension and now wouldnt have a router without one ! In fact ive just bought another one for the dedicated router in the Legacy Grin

. One turn of the alan key and the cutter is locked in , better than messing around with a spanner ! Ive used it with raised panel cutters and it really does hold them in there . The xtreme is better for router tables and the Legacy but there is also the Eliminator chuck for hand held work . Try Roger here .....http://www.woodworkersworkshop.co.uk/ Expensive but you wont regret it !

Wolf these are the collets from the Trend on the left and the CMT on the right. The CMT is a 1/4" extension the Trend is a 1/4" collet that fits into the 1/2" extension so it is not exactly like for like.

the only thing that keeps me well away from things like the extreme collet extension, is the very fact they have a grub screw to retain the cutter, unless there is a leather washer (very much doubt!!!) there is always the ability of it working loose, and that is not taking into account of the fact the thing will rotate slightly out of balance!!! and the higher the rpm, the greater the eventual and hastened wear upon the routers bearings ............

but that is my personal opinion and experience!! only.....

pretty much my thoughts
you double the unsupported shaft length you must more than double the wear on the bearing due to leverage
you are also like you say wolf amplifying any slightly out of true running

another concern i have is the base of the woolf craft router table i use is pressed steel and any extra leverage will cause it to move out of true[tipping the cutter by a tiny amount]

so i am planning on covering the top with 12mm mdf which with help with larger cutters[bigger than the hole in the metal top] that have to go sub surface to line up
screw the metal and mdf together in several places
then secure the router with 3 or 4 no 6 or 8 countersunk machine bolts and spring washers
throught the mdf steel and purpose made holes in the router base

any critisism suggestions or comments welcome Grin

ok [matt] wolf Grin

the collett arrived today very well engeneered and i mean great tollerences Grin

the grub screw isnt is an allen screw that tightens across the edge of the collet and pulls a wedge shaped hard metal peice with the footprint of a pencil with a shallow cut from the outside edge towards the centre
a quarter to half turn of the allen[hex] key fully tightens the router cutter

the extension is also very good fit into the machines collet

they have comprehensive instructions about possible collet misalinement causing possible vibration and complete safety instructions and solutions

You need to balance the xtension before you use it . I bought the xtension because i had a raised panel cutter come out and fly across the workshop . My own fault i didnt check the RPM after sticking the router in for a service . A normal collet has the "wobble" so this is even more so with a trend extended collet . The xtreme or Eliminator if balanced right gets rid of the wobble so no flying cutters . There are two rubber washers along with the wedge that hold the cutter in place . I take them out myself as they are a PITA but im told i shouldnt , not had a cutter come out yet .
