Spi 98-319-7 Mechanical Center Finder Set 5 Piece

Product Description

The SPI 98-319-7 is a mechanical center finder set designed for locating the center and edges of workpieces on milling machines, drill presses, and similar machine tools. The set achieves an accuracy of 0.0002 inches, making it well-suited for precision setup work in a production or job shop environment. The head measures 0.1 inches in diameter. Four attachments are included along with a holder and protective case, giving machinists the flexibility to handle a range of centering and edge-finding tasks with a single organized kit. Total package contents come to 5 pieces.

This center finder set is used in metalworking and machining applications where accurate workpiece location is critical before cutting operations begin. Typical scenarios include setting up vise-held parts on a vertical mill, locating hole centers on a drill press, or establishing datums on a CNC machining center during manual setup. The compact head diameter of 0.1 inches allows use in tight setups where larger finders would interfere with fixturing or part geometry. The included case keeps all attachments organized and protected between uses.

Installation Notes

Center finder sets are installed and used by machinists and toolroom professionals. Secure the holder in the machine spindle using the appropriate collet or toolholder before use. Ensure the spindle is rotating at a low, appropriate RPM before contacting the workpiece, and never exceed the speed rating for the finder head. Power down and lock out the machine before changing attachments or removing the tool from the holder.
