Defining High Feed End Mills

[Motorsports-X]

Ive read through the forums and found that most people are defining their high feed end mills as a bull nose.    Im using this tool https://catalog.tungaloy.com/item.aspx?cat=6735264&fnum=1707&mapp=ml&app=562&Lang=en&GFSTYP=i&isoD=      with the high feed HJ Inserts.  Ive got got diamater at 1.25 but Im not seeing how to figure the radius that should be used.  Any suggestions?

I only have experience with helical high feed endmills, on their site they have the file available for download that has a 2d wireframe of the tool profile where you just create a custom tool with the geometry from a certain level in mastercam.

Since high feed endmills typically have multiple radii on the cutting edge, I'd suggest just getting the .STP or .DXF from tungaloy. (on the tool description page you posted, under "files package" you can apply for said files (weird they wouldn't just give them lol)

Or, just go caveman and put the tool on your optical comparator and get all the angles and radii, scribble it down on a napkin, and punch all the relevant data into the tool description window.
