Starrett Countersink Gage Range

Starrett Countersink Gages are dial indicator countersink gages, also called countersink gauges. They measure the major (top) diameter of a countersink bore quickly and accurately. The gage cone is machined to match the angle of the countersink being checked. It seats on the angled wall of the countersink, unlike a chamfer gage, which rests on the top edge of the chamfer.

Key Features:

• Direct-reading design: reads the large diameter of the countersink directly, with no calculation needed
• Multiple angle and range options: the line is offered in three different countersink angles, in inch and metric versions
• Hardened tool steel: all ground surfaces are hardened tool steel for wear resistance and long service life
• AGD-design indicator: a precision dial indicator for easy, repeatable readings
• Reading hold: the indicator reading stays in place after the gage is removed from the part, until the reset button is pressed
• Set master ring: a setting master is furnished with each gage for calibration and setting
• Made in the USA by Starrett

How to Use: Press the button on top of the indicator and firmly seat the gage head in the countersink. Release it, then read the dial. Starrett Countersink Gages suit machine shops, aerospace and fabrication work, and quality control inspection wherever countersunk fasteners must fit precisely.
