The tool uses a conical contact head with a 0.2-inch head diameter and mounts via a 3\/8-inch shank. It operates without batteries or electronics, relying on mechanical deflection to indicate centerline position. Machinists and toolmakers use this type of center finder during workpiece setup to achieve repeatable, accurate part registration before cutting operations begin.\u003c\/p\u003e\n\u003cp\u003eThis center finder suits light industrial and job-shop applications where fast, reliable center location is needed. It is well suited for use in CNC machining centers, manual knee mills, and drill press setups where a standard 3\/8-inch tool holder or collet is available. The single-end configuration keeps the tool compact and easy to handle during fixturing. Typical users include machinists, toolroom technicians, and precision metalworkers performing workholding and part alignment tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMechanical operation requires no power source or electronics\u003c\/li\u003e\n  \u003cli\u003eConical contact head for consistent centerline contact on round and cylindrical features\u003c\/li\u003e\n  \u003cli\u003e0.2-inch head diameter suited for locating small bores and center-punched marks\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter fits standard collets and tool holders\u003c\/li\u003e\n  \u003cli\u003eSingle-end design for straightforward chuck-up and use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with machine tool spindles and toolholders accepting a 3\/8-inch shank, including standard collet chucks on vertical mills, CNC machining centers, and drill presses.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists as part of workpiece setup. Power down or engage the spindle lock before inserting or removing the tool from the holder. Secure the shank fully in the collet or chuck to the appropriate holding depth before running the spindle. Follow standard shop safety practices and machine manufacturer guidelines when using edge finders and center finders at operating speed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Center Finder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Type\u003c\/strong\u003e: Mechanical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Contact Type\u003c\/strong\u003e: Conical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 98-323-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51714986344754,"sku":"98-323-9","price":22.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19ae31adc6555cdecda23a9a22ca5775.jpg?v=1788508622","url":"https:\/\/voomisupply.com\/products\/spi-98-323-9-center-finder-0-2-in-head-3-8-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
