Maybe you could use a taper pin reamer. There are plenty about on the web but you might be a bit limited with angles. Or something like this

What do you need the tapered holes for.

Take a look here, they do 7 degree cutters:

not ultra cheap, but I'm told their quality is good.

Hi there.
I know this is months ago, but.
If it is any help you can cut, straight, convex and concave tapered holes with the software CAMBAM (£97) and its free to download a trial that allows you to use it 40 times with no limits.
You select the hole you want to cut in the viewer and select profile operation. In the properties section of this operation you just created, set for inside profile, and then set the options for side profile shape (straight, convex, etc) and the angle in degrees (I think it is degrees). CAMBAM will then calculate the path based on the cutter details you have selected.
regards

Interesting, thanks for that. Does it allow you to do chamfers with an arbitrary angle around the edge of a part as well by any chance??

Yes.
Examples here show circles but any shape will do.

There's also a "Break Edges" plugin I use for chamfers but angle depends upon the V tool used.

Another, but slower method, would be to create a 3D surface with required chamfers then use a 3D Machining Operation.Last edited by EddyCurrent; 18-12-2020 at 08:42 AM.

Cheers for that, I might buy Cambam then. I'd thought of the 3D route, but as you say, slower to machine (and draw up!) when the job's mostly profiling with a few angled edges.

I like Cambam a lot, it's easy to master but powerful as well. It is greatly improved by the large selection of plug-ins available to extend it's capabilities and the support forum that backs them up. The trick is knowing where to find them...
