Desert_woodworker, do you have experience with a certain brand and style from that site?

Bits need to be clean and sharp. Check your edges, use a find diamond hone on flat side of carbide to re-sharpen them periodically might help.

There are a lot of sources for CNC router bits. Depends heavily on application and wood being cut.
In the link above – Amana has many product lines targeted towards the smaller table top CNC machines commonly sold for wood working. Amana even has a 1/2 shaft bit with replaceable inserts for different cutting shapes. You can also call Holbren for help selecting Amama CNC bits for you application.

One source for CNC tools I use is MSC direct. You can find everything from cheap as dirt one time use HSS straight cut to exotic full carbide up/down spiral cut bits. You can get generic 1/4” full carbide double helix spiral (up/down cut) bits for less than half cost of regular router bits found from normal woodworking sources.

Best Luck.

I actually work on a cnc machine
we use Belin router bits..very good quality bits…we buy them direct through Multicam.
Or Acme in Toronto…I`m in Canada so not sure what the American equivalent would be:)

I use a lot of Amana bits. While they’re not available in really small sizes, I really like the Amana bits with the replaceable blade. It makes honing them easy as you can remove the blade from the bit and you can replace just the blade if they get really dull.

One thing to watch out for is the chip load as specified by the bit maker. Since your Dewalt router is basically fixed rpm, you should make sure your feed velocity is matched for proper chip load. This will help with bit life in the long term.

Thanks,
Mike

I use Amana Bits, and really like them. I started with them and have had real good luck. I’ve not bought sets, and slowly got a good stable of bits, and even bought a flycutter for flattening my 4×8 table. I have a cnc routerparts table i built from a kit. Love it.

Thank you so much CaptainKlutz, bredro, MikeDS, and bonesbr549! I really like the sound of that Amana with replaceable blades. Usually stuff like that is crap, but if you guys have had good luck, I’m willing to give it a go! Off to do so shopping and comparing!

I love Amana bits but there are others that are just as good or better!
Onsrud, very good and a lot of information on their site!
Niagara, I have used there without an issue.
Kodiak, I like these too.

There are probably other ones I have not tried as yet.
My son is a CNC machinist and he gets me more info than I can assimilate about cutters.

Whiteside SC40, very popular bit for the round nose

Thanks Holbren, I forgot Whiteside and I even have two of their bits!
