Starrett 53067 Center Finder 0.25 Inch Ball Contact

Product Description

The STARRETT 53067 is a mechanical center finder designed for locating the center of round stock, holes, and cylindrical workpieces on mills, lathes, and drill presses. It uses a spring-loaded ball contact head with a 0.25-inch diameter to detect runout visually as the spindle rotates, allowing the operator to walk the tool into center without electronic readouts or edge-finding electronics. The 3/8-inch shank fits standard collets and drill chucks. The body is constructed from steel for durability in shop environments. This tool is a standard in the toolkits of machinists, toolmakers, and setup technicians.

The 53067 is suited for manual milling machines, CNC setups requiring manual edge-finding, and drill press centering operations in both production and job-shop settings. Its mechanical ball contact operation requires no batteries or calibration, making it a low-maintenance option for everyday centering tasks. The single-end configuration keeps the setup straightforward. Typical users include machinists and metalworking professionals who need a fast, repeatable method for spindle-to-workpiece center alignment.
