Who's used an annular cutter on their mill?

A DIY arbor would be great in O1 tool steel so it can be heat treated. O1 is very expensive when you start getting into 1" diameter and up.
An R8 is a lot of work to turn and takes a lot of skill. Maybe down the line, I may revisit annular cutters again, but for now, I don't really have a need.

scwhite,

These aren't endmills, they are only for drilling holes. Any time you are using them you will have pressure keeping the rotobroach in the collet.

Could I use an old R8 JT arbor and turn it into an arbor for smaller annular cutters? 3/4" shank cutters?
 
If they made an arbor for annular cutters in straight shank or R8, that is reasonably priced, that would be great.
Making one from O1 tool steel then heat treating is a fairly expensive and time consuming proposition.
 
Hougen does make a USA quality made arbor for $67.00, coolant collar optional. These arbors are used with 12,000 series/1" DOC tools. 3/4" , but this one is NOT for machine tools. The correct arbor for machines costs around $185.00 for R8 or SS. The one pictured is for stationary tools and drill chucks. Maybe I'll find a good one on Ebay for less.
