It adds reach to the micrometer assembly, allowing technicians to measure bore depths and internal diameters that fall outside the standard range of the base instrument. The extension accommodates a maximum measurement of 6 inches and provides an extension range from 0.5 inches to 0.8 inches. Machinists, toolroom technicians, and precision measurement professionals install this accessory when working with deep bores or stepped features that require extended reach without sacrificing measurement accuracy.\u003c\/p\u003e\n\u003cp\u003eThis extension is suited for precision metrology applications in machine shops, manufacturing environments, and toolrooms. It is used whenever the base Hole-Mike micrometer cannot reach the target measurement depth or diameter on its own. The 10-727-6 is intended for bench-level and in-machine bore inspection work where repeatable, traceable measurements are required. It weighs 0.85 pounds and is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtends measurement range up to 6 inches maximum measurement depth\u003c\/li\u003e\n  \u003cli\u003eExtension range of 0.5 inches minimum to 0.8 inches maximum\u003c\/li\u003e\n  \u003cli\u003eDesigned as a direct accessory for SPI Hole-Mike Series micrometers\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.85 pounds for easy handling at the workstation\u003c\/li\u003e\n  \u003cli\u003eOverall length of 6 inches for consistent reach in deep-bore applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SPI Hole-Mike Series micrometers as a direct accessory extension.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis extension is installed by a machinist or metrology technician at the workbench or measurement station. Before attaching or removing the extension, ensure the micrometer is clear of any workpiece and the measuring faces are protected from contact damage. Follow the micrometer manufacturer instructions for proper thread engagement and seating of the extension to maintain calibration integrity. Do not overtighten the extension joint, as this can affect measurement accuracy and damage the instrument threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Extension\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: SPI Hole-Mike Series Micrometer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Extension\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Extension\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 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: 10-727-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51700035977522,"sku":"10-727-6","price":113.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a4b75df93398c259cc1d39df9b92eb1.jpg?v=1788385228","url":"https:\/\/voomisupply.com\/products\/spi-10-727-6-micrometer-extension-hole-mike-series","provider":"Voomi Supply","version":"1.0","type":"link"}
