My invention relates to combination gages such as are used by machinists in constructing and truing-up tools and work of various kinds, and it has for its object to produce a gage of simple and convenient form and construction which may be used in gauging the cutting-points of screw-cutting tools or other similar external angles, in gaging the incline or angle of V-shaped threads or other similar interior angles, and in gauging corners of various angles, preferably square corners, the corners of hexagons or other corners of one hundred and twenty degrees, and the corners of octagons or other corners of one hundred and thirty-five degrees. |
