Since it is impossible to use it so that it will not break below φ 0.3, it is not necessary. To that extent you should add 0.85 or 0.95. Whether it is necessary to make a separate set if necessary. (It is convenient to buy and repurchase)
I'm making a hole to attach Heaton to the nut trimmer.

I could not use it because I thought that the drill set had a chuck attached. Today, I ordered additional chucks, but please allow me to think about set sale with chuck and to purchase multiple drills of a certain size only.
