Cutting bit shank
The shanks are pretty hard, making them hard to shorten - you have to sacrifice a long drill bit because the short ones are hard to hold while you shorten them.
Then you have to re-point them, and being very short they are difficult to hold on to. And, you need to be good at getting a cutting point back on them.
I tried this and because I am not good at re-pointing drill bits using a belt sander I was not very successful.
I ended up resorting to pulling the flap extender assembly out to drill that hole, it took some time, you don't have to buy the right angle drill (I do have one and tried to drill it that way but it was hard to get the hole right where I wanted it), and you can drill the hole right where you want to.
