Rockler Router Collet Extension for 1/2'' Shank Bits
Gives you the extra lift you need for comfortable, convenient above table bit changes, as well as additional depth of cut.
Item #
53895

This collet extender allows you to change router bits from above the table—even without a lift! Even if you have a lift, they still make bit changes easier because you won't have to remove the insert ring. They're also great for custom made router tables with very thick tops, as they provide the additional depth of cut needed for many routing tasks. Use them with our Router Table Spline Jig (#59288, sold separately) to achieve full depth of cut when machining dovetail splines.

The collet extender is fine, but I found that it would not do what I wanted. I wanted to return it but found that you have a very poor return policy which makes returning it not worth while. Guess I'll just drop it into the bottom of my tool box and not buy anything more from Rockler. Too bad.

Router collet extention
I'm making a walnut slab coffee table, and I needed to flatten it. This extension, along with an inch and a half bit and a shop built sled, doe the job that I needed done.

Excellent, would highly recommend
I highly recommend this extension especially if you are planing slabs of wood. The extra reach made available by the extension greatly reduces the amount of time needed to adjust your planing jig to change the depth of cut!

Awesome!
I needed an extension to mount my plunge router to a table since the bit did not reach the top of the table. This extension works great...and it's safe!

High quality
This is a very well made collet extension. The collet has the same style holding power as the router collet itself. Holds well performing deep cuts or when extra bit length is needs. You can use this collet extension with complete confidence that it will hold your bit firmly. Well worth the cost. Don't cheap out with other styles extensions that use set screws to secure the bit!

Extending the bits above the table
Looks and works great but the product should have additional shanks available, none of my shanks fit this unit.

It says to only use with variable speed router; what are the guidelines for speeds relative to bit sizes?
BEST ANSWER: I have used both the 1/4 and 1/2" extensions for about 2 yrs., occasional use, with no problems. I use them with a Freud 3 1/4 hp. router mounted on a router table. The guidelines re: speeds may vary based on the router manufacturers recommendations. For my Freud the recommendations are:
Bit Diameter Max RPM
1" 24,000
1-1/4 18,000
2-1/4 16,000
3-1/2 12,000
I recommend you contact your router manufacturer for their speed recommendations. I normally run my router on 18,000 rpm, and have used both extensions at that speed with excellent results.

this bit is 1/4 to 1/2 '' ?
BEST ANSWER: Rockler makes two extensions. This one will fit router bits with a 1/2" diameter shank. They also sell another extension for router bits with a 1/4" diameter shank. The extension themselves (both of them) require a router with a 1/2" collet. I recommend that you seriously consider getting both sizes (for 1/4" and 1/2" shank router bits). These are heavy duty extensions. I have both and have been perfectly satisfied.

What size wrenches do you need for Router collet extension?
BEST ANSWER: The extension goes into the router the same as any router bit and then to tighten the router bit into the extension requires a 1 1/8" wrench at the top and a 3/4" wrench at the bottom. The top is the same wrench used to tighten the collet on your router.

What is the diameter of the collet?
BEST ANSWER: There are 2 models of this extender. One for 1/2 Inch bits and one for 1/4 inch bits. both have 1/2 inch shanks. So you need a router with 1/2 inch collet to run either one. I have a big Milwaukee router and they did not work because the router would not lower enough to get the bit at a working height. In other words they were too long. They might work with a plunge router or some other arrangement where the router is not fastened to the bottom of the table.

Could anyone tell me the distance it will extend your bit. From the first notch where it seats against the routers collet to the top of the collet extension?
BEST ANSWER: This distance is about 2 inches. I purchased one of these but can not use it because my router motor dose not go low enough to operate safely.

can this be used in a hand held router to increase the depth of cut using a dish cutting bit?
