Anyone using a drill doctor, and have any comments on effectiveness? A guy at
work says he has used one and it works great to sharpen dull bits. I would
think that it might easily go thru the heat treat layer, but maybe it doesn't
for one sharpening. The bits I get these days seem to be pretty low quality.
Being able to sharpen them and get more life out of them would be nice. Thanks
for any comments.
Dave
