118° And 135° Drill Point Grinding Gauge
A flat gauge for checking twist drills while you sharpen them. Lay the shank against the fence and slide it into the V: the right face is set at 59° for a 118° point and the left face at 67.5° for a 135° point. Each face has tick marks every 5 mm for comparing lip lengths. The body is 112 x 50 x 12 mm and takes drills up to about 13 mm, and there is a 5 mm hole for hanging it on a pegboard.
