A side view of the parts of the gage is shown as marked O.
lThis gage thus constructed is applied to the bit or auger, as shown in the drawing, (marked D,) an d by loosening the screws maybe moved up or down at pleasure, gaging accurately the depth required to be bored.
The clamp I construct of iron, brass, copper, or other suitable metal.
What I claim as my invention, and desire to secure by Letters Patent, is-
A gage for bits andaugers composed of two pieces, A A, formed to tit the faces of the twisted blade ofthe bit or auger so as to turn with the spiral twist and adjustably united by set-screws, substantially as andfor the purpose set forth. l
