Part, Vise and Fixture Probing: Automatically Set Zero points fast and accurate.
Use the KP-3 probe to quickly and accurately find zero points on a vise, fixture or part. Eliminate operator error when setting zero points, finding edges, or center locations of bosses or bores, slots and webs. Eliminates the need for a centerfinder or an edgefinder. You'll never have to spend 30 minutes using a center finder to locate the center of a bore again. The probe will find and set the center of a bore in just seconds. In addition, the probe can be used to verify part dimensions and locations and many other applications. The KP-3 mounts in any 1/2" or 10mm tool holder and has concentric adjustment screws. Also compatible with Mach3/4, WinCNC, LinuxCNC, Pathpilot and others.

Replacement or additional probe tips can be purchased here.

I am using the KP3 for a long time now, and it never needs to have the centering readjusted. Excellent repeatability and its spring load is high enough to use a longer stylus. Very fast 2day delivery to Germany.
