Quick and dirty drill gage

[hemmjo]

Is that supposed to be a single gauge for many drill sizes or one for just one drill size? If it if for multiple drill sizes, how do you use it?

You would place the bit against the side of the tool instead of in the center which would verify the angle, but not the equal length of each side. It is much more difficult to get the angle correct than it is the length, when sharpening by hand.

You still need to develop some skills to get the rake and assure equal length of the cutting edges.
