This precision instrument is designed to measure the top (major) countersink diameter, providing fast, accurate, and repeatable readings. It reads directly in .002 inch or .05 mm diameter increments on the dial face, making it suitable for various applications including chamfers, countersinks, hydraulic fittings, screw machine parts, and aircraft components.
- Exact angle gaging plunger alerts the operator of incorrect countersink angles.
- Peak hold mechanism allows for one-hand operation.
- Includes a calibrated setting ring.
- Comes with a foam-lined storage case and operating instructions.
