Spi 98-326-2 Edge Center Finder Mechanical Double End

Product Description

The SPI 98-326-2 is a mechanical edge and center finder designed for use in milling machines, machining centers, and drill presses. It locates workpiece edges and center points with an accuracy of 0.0002 inches (5 micrometers), making it a reliable tool for setup work that demands repeatable precision. The double-end design provides both a conical contact and a cylindrical contact tip, giving machinists two options in a single tool. With a 0.5-inch shank diameter, it seats directly in standard collets and tool holders commonly found in manual and CNC milling setups. Machinists, tool-and-die makers, and CNC operators use this type of finder during workpiece setup before cutting operations begin.

The SPI 98-326-2 is suited for machine shop environments where accurate edge detection is required before starting a machining operation. The conical contact tip is used for finding center points on drilled holes or punched marks, while the cylindrical tip locates straight edges. This tool is appropriate for use in both job shop and production environments handling metal and similar rigid workpiece materials. No batteries or power source are required — the mechanical operation makes it simple to use and maintain.

Key Features

• 0.0002 inch (5 micrometer) accuracy for precise workpiece setup
• Double-end design with both conical and cylindrical contact tips
• 0.5-inch shank diameter fits standard collets and tool holders
• 0.2-inch head diameter for access in tight or recessed areas
• Mechanical operation — no power source required
• Non-magnetic construction

Compatibility

Designed as a standard replacement or addition for machine shop setups requiring a mechanical edge and center finder with a 0.5-inch shank diameter. Fits any milling machine or machining center collet or tool holder that accepts a 0.5-inch straight shank.

Installation Notes

Installation is performed by a machinist during machine setup. Insert the 0.5-inch shank into a collet or tool holder and tighten to the machine manufacturer's specified torque. Ensure the spindle speed is set to the appropriate RPM for edge-finding operations before use — running at excessive speed can damage the contact tip. Always secure the workpiece firmly before beginning the edge-finding procedure.
