I am looking to find a 3/8" collet adaptor for my Ryobi. It has the half inch chuck, and uses a1/4" adapter in it. Ryobi made a 3/8" adaptor for it under the part number of 6072213, but it is no longer made.

The idea of taking a 1/4" collet, holding it with vice grips and drilling it to 3/8" does not thrill me. At 22,000 RPM, I want the assurance of something factory made.

The question remains, is there another source for a 1/2" to 3/8" adaptor?

Most respectfully

Michael

Hi Michael
Just asking , why not just stick with the 1/2" shank and the 1/4" shank router bits and just forget the 3/8" shank router bits.
Trying to drill out a collet will not work,the collects are high temp steel.(D.H.T.)
You can make one on a lathe and then heat treat it,but that's alot of work for a part you will not use to many times or find to many bits in the 3/8" shank size.

Just asking :)

Hey Michael

While searching some eBay listings the other night, I saw an auction for a variety of router adaptors but I can't remember where I was looking or what brand they were. :eek: Must be an age thing. :eek:

If you have time to wait, you can run a search on eBay for your Ryobi adaptor and eventually an auction or sale will come up.


Not sure this will help you but Porter Cable makes an 1/2" to 3/8" adaptor #42133. Check the web for it.

Also Woodworkingcom has a 1/2" to 3/8" adaptor, see url

bobj3: To answer your question, I have about 35 Carbide router bits in 3/8ths. (HFT's competitor had a heck of a deal on them.) They work great in my hand held PC, but I really wanted to use them in the table. As a business teacher I should know that a bargain is not always a bargain.

As far as milling or turning an adaptor myself; my austaire version of a lathe would be a pair of vice grip pliars and an electric drill.

Labric: Thank you for the URLs. I thought of that E-Bay thing and will keep trying it.

Have you considered contacting Ryobi directly to see if they offer a 3/8" collet? May be faster not necessarily cheaper way to go but, it is an option to consider.

Got ya, when you have 35 bargain Carbide router bits it may worth the time to run down a collet.
I'm from the old school when you can find one you make one.
I have made many tools with just a elec. drill,bolt,and a belt grinder.
It may take a time or two to get it right.
Here's a link that you may want to check out.
http://www.Grizzly.com look up items G-1227 and G-1638 both are .375"id.
It's worth a shot and then maybe not.

It's Just a thought.

Labric's URL paid off. They have what I need and it will be here in time for spring break.
I do appreciate all the ideas and assistance.

Respectfully

Michael, thank you for your post. It was very helpful to me, as I have exactly the same need, with two 3/8" collet routers and a newly purchased 1/2"collet Roybi plunge router (picked up at an estate sale for $10). All of my router bits are 3/8", so the idea of a 1/2" to 3/8" adapter was attractive to me. Additionally, I wasn't so concerned that drilling a hole to enlarge the 1/4" ID to 3/8" ID would weaken the materials as I was concerned that the larger ID would end up not concentric with the OD, causing a wobble. Using the link labric provided took me to a Highland Woodworkers website, where the adapter was $15.98, including shipping. Further web searches revealed the same item at the Hartville Tool website for $10.88, with free shipping. Today is a good day.:sold:

1/2" to 3/8" reducer sleeves are not brand specific, any brand of correct size sleeve will fit any brand of 1/2" router collet. A quick E bay search brought up these two but I'm sure that a deeper search will find many more and cheaper.
3/8" router sleeves | eBay
These are my two 1/2" to 3/8" reducers, on the left is a Makita and on the right a more precision MUSCLECHUCK.

EDIT-reviewing this post I realized that the MUSCLECHUCKsleeve on the right isn't a 3/8", it's an 8mm. I don't in fact have any 3/8" router bits but I do have 3/8" end mills and slot cutters and occasionally I have a need for perfectly flat bottom holes, hence the Makita sleeve.
