Chamfer Gauges
Check the top diameter of chamfered holes to make sure they’re within tolerance. These gauges are often used for quality control in milling, drilling, and reaming. Press the three-blade probe into a chamfered hole and twist slightly to center. Once the blades touch the hole’s slopes, the dial will display the diameter. Zero-set these gauges on a flat, ground surface when needed.
Choose a gauge with a measuring angle that’s greater than or equal to the angle of the chamfered hole you’re measuring.

Electronic Chamfer Gauges
Whether a chamfered edge is in a screw hole or on the end of a rotary shaft, these gauges find its diameter. Use them to confirm the tolerance of edges after milling, drilling, and reaming. They measure chamfers on the inside or outside diameter of your bore. As you trace the probe of these gauges along an edge, an internal sensor records the distance and angle. The calculated diameter displays on the LCD screen for quick readings. All have SPC data output to transfer information to your computer or data processor—you don’t even need any cables.
Choose a gauge with an angle that is greater than or equal to the chamfer angle you are trying to measure.

Starrett Chamfer Gauges
Make sure the top diameter of a chamfered hole isn’t too big or too small. These gauges are often used as a quality control check after milling, drilling, and reaming. Press the three-blade probe into a chamfered hole and twist slightly to center. Once the blades touch the hole’s slopes, the dial will display the diameter. Zero set these gauges on a flat, ground surface when needed.
Choose a gauge with a measuring angle that’s greater than or equal to the angle of the chamfered hole you’re measuring.
