General Purpose Charts

General purpose charts are available with either a clear or matte finish. They all carry horizontal and vertical centerlines; other angel lines are indicated below. Charts with 30°, 45° and 60° lines are most useful in a tool room where chamfers, form tools and threads have to be inspected.
