Find the exact edge of a workpiece without math or guesswork to quickly align your machining setup. Unlike most edge finders, these indicators don't require you to monitor the contact point's position and then add or subtract its diameter. When the display shows zero, that's your edge. These indicators move along three axes, so you can also use them to measure part dimensions, check surface flatness, and locate the centers of holes. The display swivels, eliminating the need to lean into your machine or set up mirrors to measure the back of your part.

Insert these indicators into your CNC or manual milling machine, adjust the set screws at the top to calibrate them, and they're ready to go. To stop the indicator from breaking, the contact point has a ceramic body that fractures if it collides with your part. Just screw on a new contact point to replace it without having to re-calibrate.
