Looking for a custom router bit fabricator

[david.78737]

I need a "thumbnail" router bit.  Stock profiles are too big and also use a pilot bearing.  Not what I am looking for.

What I want is a similar profile to the "thumbnail" bit but much more shallow removing about 5/32" material across 1.25" of the stock.  The bit would be about 2.625" diameter with 1/2" dia shank to use in the CNC at the HS.  So I'll need to locate a tool fabricator to make it.

Some in the CNC world might suggest just using a bullnose mill and make multiple passes to arrive at a contour.  But the pieces are irregular and the time to fabricate with a small CNC bit would be excessive and I wouldn't begin to figure out how to draw the V Carve file.  This profile bit would eliminate a considerable amount of machine time and programming time.

If anybody has experience with this I would appreciate a recommendation.

Thanks David Richardson

Whiteside tool will make custom bits.  And you can put your own profile on a steel rabbeting bit with a grinder, you just have to be careful about it

 As far as the v-carve thing, in case it could help someone else, the moulding toolpaths in 8.5 and up are easy to use, and do exactly what you described.

I had one toy as a kid and it was a stick with a holey sock tied to it.
