The spindle square allows an indicator to be positioned at a precise right angle to a spindle or quill, enabling accurate perpendicularity checks and setup verification on milling machines, drill presses, and similar equipment. The shank diameter measures 0.38 inches for a secure fit in standard tool holders, and the graduation resolution is 0.001 inches, supporting precision work where tight tolerances are required. Licensed machinists, toolroom technicians, and metrologists are the primary users of this accessory.\u003c\/p\u003e\n\u003cp\u003eThis spindle square is suited for machine tool setup in both production and toolroom environments. It is used when a technician needs to verify that a spindle or quill is running true and perpendicular to the table surface before beginning a machining operation. The accessory accommodates all machine types as specified by the manufacturer, making it a versatile addition to a shop's indicator tooling inventory. It ships as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.38 inch shank diameter for compatibility with standard collets and tool holders\u003c\/li\u003e\n  \u003cli\u003e0.001 inch graduation resolution for precision perpendicularity measurement\u003c\/li\u003e\n  \u003cli\u003eDrop indicator mounting style allows quick attachment and removal\u003c\/li\u003e\n  \u003cli\u003eSuitable for use with all machine types as rated by the manufacturer\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 41111600 for procurement and cataloging systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with all machines as specified by the manufacturer, compatible with dial and digital drop indicators that accept a standard spindle square accessory.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Before mounting the spindle square, power down the machine and ensure the spindle is locked or at rest. Insert the shank into the appropriate collet or holder and tighten securely per the machine manufacturer's recommended clamping procedure. Handle indicator accessories with care to avoid impacts that could affect calibration accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Spindle Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Shank Diameter\u003c\/strong\u003e: 0.194 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation (Decimal Inch)\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 20-910-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51717385617714,"sku":"20-910-6","price":307.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57681438ca955c341a467bf762a516e1.jpg?v=1788539565","url":"https:\/\/voomisupply.com\/products\/spi-20-910-6-drop-indicator-spindle-square","provider":"Voomi Supply","version":"1.0","type":"link"}
