The idea is to do holes and internal cuts with just one tool. Here is what I did:
5/8 spade bit is painted black to make a drawing on it.
.
Made all the cuts with dremel using cut-off disks. On left is a tool holder (was a bit a challenge to make it from steal)
.
one cutting side
.
other side
.
left side of the tool has cutting edge on the bottom
.
Centering the tool.
.
First cut almost as deep as 2 inch
.
view of the “undercut” after i made a few holes.
Hopefully the end result will be shown on the next blog

This looks absolutely brilliant Yuri. I wonder if it could be used as a handheld tool? This is a real innovative breakthrough in tool design for this type of work. Congratulations for coming up with this solution which shows a lot of expertise and creative thinking. I’m looking forward to your next blog on this.

I echo Mike’s comment.
This is design ingenuity at work.
Something special, Yuri.
