Turning - Boring with an End Mill

[mbystry]

On my manual lathe I often times bore holes with a two-flute end mill. For instance, if I want a .300" diameter hole bored into some round stock, I'll chuck up a .25" end mill, drill a hole and then cross slide out to .300". I do this so I don't have to change tooling between a twist drill and an actual boring bar.

I'm trying to program this on my cnc lathe but I'm unable to pick an end mill as my boring bar. Is there a way that I Can fool HSM (2019)?

you can start with a boring bar and define as close as you can to your end mill. Then in the tools description label it the end mill you want to use. The last tool in picture (tool 10) is doing a boring operation.

Alright. I'll give it a go. Thank-you for the tip.
