Router Xtreme Xtension™

Item #
80% of 100

Change router bits from above the table with only one tool - PLUS extend router bit's reach. No need to lock your spindle - single locking screw secures the bit. Use this extension with any router table or with any router lift and It also is not to be used with fixed based routers because when extended they do not have a long enough housing to lower or raise the router in the housing and safely retain enough clamping pressure of the housing on the motor body to securely capture the motor.

Notice: Cannot be used with fixed base single speed or handheld router operations without significant modification of router base.
(1) Router Xtreme Xtension
(1) 1/4" x 1/2" reduction sleeve to safely support 1/4" cutters
(1) 5/32" Allen wrench and locking screw

I have used one of these for a few years now in my router table. Made changing of the bits much easier and I have not seen any performance issues. I mostly used 1/2" shanks but I do have collet reducers, just haven't used them yet. I try to stick with 1/2" shanks.

The Router Xtreme Xtension is great....
The Router Xtreme Xtension is great. I have a Dewalt Router which is a great router. My router is a under the table mount. In order to change out bits, I have to unlatch the router from the base use two wrenchs, change out the bit and replace the router. With the RXX., all I have to do is raise my router, use the allen wrench, change the bit and lower the router to the correct depth. This is a time save and easy to use!

Extension plate
Instructions on box weren’t clear that I’d have to make an extension plate in order to use. But that was fairly easy to do. Works fine.

Xtreme Xtension - 1/4" bits do not tighten
I cannot use this as the 1/4" shank router bits I have (most of what I own) will not tighten down using the adapter that came with the extender.

I've reviewed the doucmentation, made sure the adapter is inserted exactly as specified but still cannot get the extender to tighter up against my rout bits (1/4")

Maybe I am just unlucky and got one that sneaked through quality control, but, I can't fit any of my 1/4" shank router bits into the 1/4" reducer. The bore is too small.

Does it work with Bosch router ?
A shopper on Jul 5, 2015
BEST ANSWER: Any router that takes a 1/2" shank will accept this.
Will this work on the Dewalt 618 router?
Robert P on Sep 27, 2019
BEST ANSWER: Absolutely. You'll love it in a router table to make adjustments and bit changes easier above the table. Just have to use the 1/2" collet in your router. Watch the slot placement in the 1/4" collet if you use it in the extension. Instructions are clear and easy to follow.
Can the Extreme Xtension work with a Makita 3600RB router with 22000rpm?
matt W on Aug 26, 2018
BEST ANSWER: The Extreme Xtension should work with just about any router with a 1/2" collet. However, this Xtension is going to change the geometry of the way that the bit is held in the router by holding the bit further away from the motor and adding more weight to what is being held in the router's collet. This can significantly increase the run-out (run-out = how much the arbor spins out of center) in your router's arbor. All routers have some degree of run-out no matter the brand or quality. Usually .005 of an inch is considered good, but if you double the distance the bit is held from the router's motor, that .005 can become .010 or more. The run-out gets worse with age and care of the router. The bearings WILL wear with age and use (creating more run-out) and even specks of saw-dust or scratches in the collet, collet seat, or the bit's shaft can throw it off to a dangerous amount. Scratched collets and bits should be replaced immediately. Damaged collet seats should be repaired or replaced by a qualified service tech immediately.

I personally would not use the Xtension in a hand-held router. Even with a router mounted in a table, I'd be inclined to only use a variable speed router so that I could ramp up the speed slowly making test cuts to determine at what speed larger bits starts to get "grabby" or cutting rougher in a sample of the wood that I'll be using, and then turn down the speed a little when I notice the change.

Beyond that, work smarter-not harder and follow all the safety recommendations and you'll keep all your fingers and other body parts.
