The answer is yes. MLCS sells an adapter that allows 1/2" Router Bits in a
I would not reccomend it because the strain it would place on your routers
bearings. The length of the adapter would cause much force against the
bearings. If you do use it take light cuts.
As far as the people who said it didn't exist thought just because they
didn't know about the adapter no one would know. It's alled human folly.
Is it now? I think it's folly to suppose that MLCS or anyone sells such
a product. I think you've misread just slightly. If not, please tell us
what particular adapter lets you use a 1/2" shank in a 1/4" collet.
Oh, you can get these things alright. I mention them only to make it
quite plain that there's no earthly way I'd be in the same workshop as
one of them in use. I'd rather use a spindle moulder with a French
cutter in it.
Probably not how I would have worded it, but I can't quibble with the
You've gotta be kidding. The only adapters I've seen at MLCS or
anywhere else are sleeves or extensions that enable a larger collet to
take a smaller shank. I can't think how it would even work in the
opposite direction. Do you have an example of one?
I'm with you. If these things do exist, I don't want them anywhere near
Anyway, the OP's question was "can I do this," not "does a product
exist that falsely claims it can do this." I'd still say the answer is
"Jumpin' Jesus No!" :-D "Human folly" would be supposing otherwise.

| I have a Ryobi router my father bought me for Christmas. It uses 1/4
| inch bits. Can it be converted to use 1/2 bits? The reason I am
| asking is I would like to experiment with raised panel bits in my
| router table but I have never been able to find them in 1/4 inch
| shank size.
That conversion would probably pose a serious risk of personal injury.
I strongly suggest you consider a more robust, more powerful router
with speed control for this kind of router table use. Of course, these
large bits should not be used for freehand routing.

I've used this upgrade/adapter kit for the Ryobi router and it works
great with 1/2 inch bits.
Would recommend this to anyone.
That depends. Many routers are made to use either 1/4" or 1/2"
collets...if your router is one of those and you merely lack the 1/2"
collet, you can certainly buy one made for the router.
If you are unsure, unscrew the collet retaining nut, remove the collet
and measure the inside diameter of the cylinder into which the collet
fits...does it measure considerably *over* 1/2"?
I know of one made for that purpose - use it with some frequency - but
don't recall where I got it at the moment. If I remember, I'll post
the info. However, you don't need special bits to raise a panel...you
can do it with straight bits, with cove bits, with ogee bits and
others. All are available with 1/4" shanks.
