Edge Finder is a tool used in the spindle of a machine such as a mill. The device is used to accurately determine edges or markings and therefore the center of a workpiece or a previously machined feature during the set-up phase of a machining operation.

Cautions:

• Do not use the bend apart or to drag or pull with force.
• Never let impurities or foreign things stain on the slide face.
• While using edge finder, be sure the speed not over 6000 rpm.
• Never apply it on machine of horizontal type.
