Countersink Gages 687 COUNTERSINK GAGE 82º 688 COUNTERSINK GAGE 90º 689 COUNTERSINK GAGE 100º Starrett Countersink Gages are offered in three different angles so that the gage sets on the angular side of the countersink, as opposed to a chamfer gage which sets on the top edge of the chamfer. This gage directly reads the large diameter of the countersink in .002" or 0.05 mm increments. A set master ring is furnished with each gage for calibration and setting. Press the button on top of the indicator to firmly depress the gage head into the countersink. When the gage is removed, the indicator reading is held in place until the reset button is activated. All ground surfaces are of hardened tool steel. Indicators are AGD design. 687 688 689 687-3Z Countersink Gage with 695 Check Stand with F2720-4IQ Electronic Indicator 82-90-100º Diameter 687, 688, 689 Special Function Indica tors Inch Reading Countersink Gages 82º Angle 90º Angle 100º Angle Range Cat.
