I wish I could show you guys my set up (tool angles...speeds and feeds) me taking a .075 deep (.150 dia) cut with a big 1/2" 999 carbide brazed Carboloy tool bit in a KDK holder on 3" OD prehard 4140 (Maxell 3 1/2) (scale and all), mounted in a 4 jaw on my old "garage" (10 x 24 or so) Logan...or the same thang' but using the old 883 Carboloy designation but a .125 deep cut (1/4" dia) on some 'ledloy"...but, as I have shpieled around here (this site) a few times: Along with my Jet mill, like a dummy, I sold the Logan (with its 5c collet set up and all collets up to 1"!) and I am now on the hunt again...
Oops it's bugging me so I better peck it here....cutting "scale and all" above: That layer of scale will wear a groove on the cutting angle (face) of even that 999 carbide...(so its best to turn a skim cut under that scale 1st so's you don't have to grind the whole cutting angle face much when "touching up" the cutter (just the end with nose of the cutter) (like some have already said here or there around here (Smiley Face here)
