Counterbore/Countersink on the "backside" of the hole

Counterbore/Countersink on the "backside" of the hole

A backside chamfer tool is needed. It can be faked by using a Dovetail tool

A double sided one is more useful and cannot be faked.

See this link for an example.

Yes please! This is a problem for us too.

OK, I was kind of wrong. There is a way to fake it but it is less than elegant.

You can do it in the chamfer tool. The drawback is 1: The illustration can not be made to match the shaft just above the cutter head. This detail or lack of it leaves you wondering just how close that shaft really is to the hole. This is particularly important is you are using a threadmill with the undercut shaft.

2: It can be made to work but it is a big PITA juggling 3 or 4 inputs to get things to line up.

 

Example of single point thread mill that can be used for both threading and chamfering.

Thanks to libertymachine for shedding some light on this.

Check out these 2 threads as I stumble along. Yes it's doable but it makes you groan and walk away every now and then.

So, keep on voting so we can get this type of tool properly supported.

Correct illustrations and a simpler, more elegant way to input the parameters.

My personal belief is that the tool needs to be restricted to center like the thread mill and then enter the inputs.

Not to much to ask for is it?

It is also possible to perform this type of operation by adjusting the stock to leave settings while using a chamfer tool. It's also not an elegant solution, but it works. I'll attach an example for you to reference.

That said, it's definitely on our radar to have a true backside chamfer workflow.
