The set includes four attachments and accommodates both 3\/8 inch and 1\/2 inch shank diameters, giving machinists flexibility across different spindle configurations. The cylindrical contact head measures 0.5 inches in diameter and provides a repeatable, mechanical deflection signal when the spindle axis aligns with the workpiece edge. Accuracy is rated at 0.0002 inches, making this set suitable for precision setups in tool rooms, job shops, and production environments. A plastic storage sleeve is included for organized transport and protection between uses.\u003c\/p\u003e\u003cp\u003eThis edge finder set is used in manual and CNC milling operations where accurate part location is critical before cutting begins. It is a standard setup tool for machinists working with knee mills, bed mills, and vertical machining centers. The dual shank diameter compatibility makes it useful across a wide range of spindle collets and end mill holders without requiring an adapter. The four included attachments extend the versatility of the set for different edge-finding and centering tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated accuracy of 0.0002 inches for precise workpiece edge location\u003c\/li\u003e\n\u003cli\u003eCompatible with both 3\/8 inch and 1\/2 inch shank diameters\u003c\/li\u003e\n\u003cli\u003eCylindrical contact head with 0.5 inch diameter for consistent mechanical deflection\u003c\/li\u003e\n\u003cli\u003eIncludes 4 attachments to cover multiple setup applications\u003c\/li\u003e\n\u003cli\u003ePlastic sleeve included for safe storage and transport\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-purpose edge finder set for use in standard collets and end mill holders accepting 3\/8 inch or 1\/2 inch shank tooling on milling machines and machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eEdge finders are installed by a machinist into the appropriate collet or tool holder and run at a low spindle speed, typically between 500 and 1000 RPM, as recommended by standard shop practice. The spindle must be rotating before contact with the workpiece is made. Always confirm the tool is fully seated and the collet is properly tightened before use. Do not use at high spindle speeds, as this will damage the contact tip and produce inaccurate results.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch and 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Contact Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 4 attachments, plastic sleeve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FOWLER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 52-575-125-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FOWLER","offers":[{"title":"Default Title","offer_id":67916969935154,"sku":"52-575-125-0","price":89.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d1a83f4dbe886cc7b32637af82aa332.jpg?v=1791260398","url":"https:\/\/voomisupply.com\/products\/fowler-52-575-125-0-edge-finder-set-4-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
