Turning - unable to program undercut groove with tool held at 45 degree angle

Hello all, I've run into an issue that I have not seen addressed after searching through the forums. I am trying to program cutting a small undercut o-ring groove as shown below using this face grooving tool (link) held at a 45 deg angle.

 

When creating the tool, you have the option to orient it at a 45 deg angle, however then the tip tangent point is wrong (for a fixed 45 deg angle at least) and the tool is not valid for most toolpaths (this error). So I created the tool as a standard round insert tool at the standard 0 deg orientation and omitted the holder, but it will not groove in Z even with "Allow radial and axial grooving" selected (second image). Maybe that is because it is a turning general tool, but trying a grooving tool does not work because they cannot be defined as just a circle, they have an extension and again cannot be oriented at 45 deg in the tool setup. The option to change the orientation for the operation does not appear and I am not sure it would be correct for the compensation point.

 

Thanks in advance for any help you can provide!

I believe you have to program it using the tools radius/center point and not tip tangent because they still haven’t fixed this yet. Just offset to tool accordingly in your machine’s control after touching off the tool.

Thanks very much, tool centerpoint does help get a toolpath generated using the 45 degree orientation in the "Turning Groove" operation. However because the orientation is set in the operation, I can't use the same 45 degree orientation in any normal roughing operations. Doesn't really matter in this case that the tool is shown at 0 deg in other operations but might matter for more complex parts/machines.
