Hey everyone,

I have searched everywhere and I can't seem to find any company that will make a reduced shank carbide endmill.

I can find some reduced shanks that are about 0.03" smaller then the cutting diameter but I'm looking for something like 3/4" cutting diameter and a 1/2" shank. Or 1" cutting diameter with a 3/4" shank.

Does anyone know where to find this kind of bit? The longer the tool is the better...right now I'm working with MDF board and a 6" OAL 1/2" carbide 2flute upspiral endmill (Onsrud). It works great but the mold I'm milling has really steep walls and the router is very close to hitting the mold.

Any help would be greatly appreciated. I don't understand why no one would make these as I'm sure everyone would find this handy from time to time.

Thanks

This is not standard for carbide tools from any vendor I am aware of. You will have to buy the standard tools then send them out to be custom ground.

Sounds like all you need is a longer end mill.

Yeah I was thinking about going with an 8" OAL bit...the distance it's sitting out of the collet is 4.5" right now with the 6" OAL.

I remember seeing this milling tool once that had replaceable carbide inserts that you screw on. It's more like a facing tool. This would cut down the cost of the expensive over-length endmills and also has a bigger cutting diameter than the shaft. The huge difference in cutting diameter to shaft though is a bit scary.

Do you know what those tools are called?

There are inserted end mills and face mills available. Getting the right shank size with the extended reach you are asking for might be difficult. I recommend making friends with your tool salesman and let them do most of the leg work for you.

Yeah that was my next step. The problem is they handle almost everything we buy...from gloves, to bits, to rubber corn header flaps. I'll try to find an alternative and let ya know how it goes.

Thanks for you input it was helpful
