8mm or 1/4" Shank 3/8" Downcut Router Bit?

[Derek Arita]

I have a Festool 1010 router that fits a 1/4" or 8mm shank bit. I'd love to be able to use this router with my Dado Wiz, with a 3/8" downcut bit. Does anyone make an 8mm preferred or 1/4" shank bit like this?

[Jim Becker]

I don't have an answer for the source, but I highly recommend you go with an 8mm shank if you can get it...stronger than 1/4".

[Derek Arita]

Yeah, 8mm would be great, but the 3/8" cutter is the hard part. The Dado Wiz is calibrated for 1/2", 1/4" and 3/8". I use the Festool 1400 router right now, but it's kind of overkill.

[Marty Tippin]

I've never seen a spiral bit with a cutting diameter greater than the shank diameter so what you're looking for may not exist.

[Jamie Buxton]

You can buy a straight 3/8 cutter on a 1/4 shank, just not spiral. I know because I have one -- Freud I think. Do you really need the downcut?

[Derek Arita]

As with lots of tools, needs got nothing to do with it. The jig calls for a down cut because it gives a feather free dado.

Companies that make spiral tooling like Vortex can probably make them for you, but they'll be expensive.

:) I hate to admit it, but I don't have the foggiest notion what you fellows are referring to.
I know about up cut and down cut router bits, but the tools you are talking about are a mystery to me.
Not that it matters.

I've been working with wood one way or the other for 40-50 years and I am not aware of the tools you are referring to.

I can tell you that the wood is heavier than it used to be.:rolleyes:

:)I know about up cut and down cut router bits, but the tools you are talking about are a mystery to me.

An up cut bit looks like this 333559 and a down cut looks like this 333560 The up cut bit will pull the chips up toward the router as they are cut. The down cut bit will push the chips away from the router. Typically you would use and up cut bit for plunge cuts to make blind slots or holes. A down cut bit would be used for making slots that are all the way through a piece or for trimming a surface with laminate or veneer on it so that the cutting action pushes the veneer down toward the substrate instead of lifting it off the surface or creating tear out. With a down cut bit you have to have some way for the chips to escape.

OK...so lets change this up. Anyone know of an 8mm shank, 8mm downcut spiral bit...prefer carbide?

I knew about the bits, but the terminology got me. :)
