how wide should my cut-off be for parting off .125 dia barstock, but the part off side is turned down to .112 dia. i dont have a right hand cutoff (we are using a left hand), and no extended nose collet. i just started here and am implementing these things. i am currently using a .094 wide insert. i think i ned a right hand cutoff, an extended nose collet, and a .061 wide cutoff.

i have ordered this tooling, but this job turned into an expedite so im stuck with what i have. any help would be appreciated
