Hi all
I use a drill with this particular tip geometry (photos attached) and it works great for me.
What I wonder is if I could sharpen this on the Tomak, I do not think the DBS-22 can do it.
The part that worries me the most is the sharp corner in the center.
I am considering 3D printing a simple custom jig and see if I can make that work.
The surface Marked A is concave and the surface marked B is convex.
Any suggestions are much appreciated.
All my best

Welcome Per.
This is a variation of a standard conical grind with a split point.
I have done it on the Tormek, look up the thread I started recently "Musings..."
You cannot do a sharp corner like that, but you don´t need to. What counts is the cutting lip you introduce at the web.
You can do it, but you may find out that it does not pay.
Again, I have written all the pro´s and con´s related to this subject.
I did not go into depth on the fine details on how I modified the DBS-22 because there is no interest.
And maybe no need too.
Have fun,

Hi Helmut
Thank you for your help, I will check out your post and would be very interested to know how you modified the jig DBS-22 to make it happen.
I will report back when I have worked more on this.
All my best
