Digital Alignment & Positioning Indicator Advanced concept in finding zero, the true starting point of all 3-axes (X-Y-Z) on workpieces. Probe actually gets deflected in any of the 3 axes until indicator reaches centerline. At this point the workface (edge) is in direct line with the spindle. Radial run-out compensation. With the 3D tester centered in a tool holder, the workpiece edge can be positively picked up in one approach. No guessing as with electronic edge finders. Can be used on conductive and non-conductive workpieces. Electrically insulated contact point for safe applications on all CNC centers and EDM machines. Features include... 1.22" Point Length 0.158" Point Diameter 0.0002" Resolution 0.00040" Accuracy 3/4" shank
