Mitutoyo 050103 Edge Center Finder Double End Mechanical

Product Description

The MITUTOYO 050103 is a mechanical double-end edge and center finder designed for locating workpiece edges and centers on milling machines, machining centers, and similar setups. The tool features a 0.2-inch conical contact head and a 3/8-inch shank diameter, making it compatible with standard milling chucks and collets. The visual edge alert mechanism gives the operator a clear indication the moment the tool contacts the workpiece edge, eliminating guesswork during setup. At 0.2 pounds and 4.7 inches in length, it is a compact, lightweight addition to any machinist's toolbox. No batteries or power source are required — operation is entirely mechanical.

This edge and center finder is suited for use in manual mill setups and CNC workpiece probing operations where a powered probe is not required. It is commonly used by machinists, toolmakers, and setup technicians working with vises, fixtures, and rotary tables in both job shop and production environments. The double-end configuration allows the user to select either end depending on the application, providing added flexibility without swapping tools.

Key Features

• Conical contact head for accurate edge and center detection
• 0.2-inch head diameter for use in tight clearance setups
• 3/8-inch shank diameter fits standard milling chucks and collets
• Double-end design provides two working ends in a single tool
• Visual edge alert mechanism for immediate, easy-to-read contact indication
• Fully mechanical operation — no batteries or external power required

Compatibility

Designed as an OEM-style replacement and standard-use edge and center finder compatible with milling machines and machining centers that accept a 3/8-inch shank tool holder or collet.

Installation Notes

This tool is installed by machinists and setup technicians in a standard milling chuck or collet rated for a 3/8-inch shank. Before mounting, ensure the spindle is fully stopped and the machine is in a safe, locked-out state. Inspect the shank and chuck for debris before seating the tool. Do not exceed the manufacturer-recommended spindle speed for mechanical edge finders, as over-speed can damage the contact mechanism.
