drill bit sharpening without drill bit grinder

Amazon sells drill gage like the one shown for 7 bucks . I don’t think you can make one near as good for that price.

BOTH sides were the same length along the cutting face.

That's as important as the same angle. Both equally important.

Thank you Mark. I thought you would know why I wanted this info. It is for the interanal grinding spindle on my TPG. Going to try that.

You can also set the angle using a protractor like shown and use that as a grinding gauge. I also made a drill grinding gauge out of sheet metal.

Yessss that looks like what I have to get myself.I think that will solve my problem.
Thanks Charles.

I am in the same situation as you. Large drill bits are easy enough to grind freehand but the smaller bits will be very tough to sharpen that way. I have been looking at importing a Chinese drill grinder to handle the smaller bits.
This one will handle from 3mm to 30mm:

These style all work the same:

This other set-up will handle from 1mm to 28mm and will also thin the web:

It works in a slightly different way. This is the video from Kaindl, the German machine it is based on:

This one will handle end mills as well:

I could always try and find a drill grinding attachment for my Clarkson tool grinder but they are tough to find. Failing finding the attachment I could make one like this:

A drill doctor works great when you get past the learning curve.
