It extends the measurement range of compatible depth gages from 8 to 9 inches, allowing technicians and machinists to take accurate depth readings at greater reach. The rod measures 9.0 inches in overall length and has a diameter of 1\/8 inch (3.20 mm). Precise rod dimensions ensure consistent fitment and repeatable readings. This rod is a direct accessory replacement or supplemental rod for professionals who need to expand the measurement capability of an existing 440 Series setup.\u003c\/p\u003e\n\u003cp\u003eThe 71981 rod is used in machining, metrology, and inspection environments where depth measurement beyond the base range of the depth gage is required. It is suited for shop floor use, quality control stations, and toolroom applications. Machinists, tool-and-die makers, and quality inspection technicians working with precision measurement equipment are the primary users. The rod integrates into the 440 Series Micrometer Depth Gage system without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtends 440 Series Micrometer Depth Gage measurement range to 9 inches\u003c\/li\u003e\n  \u003cli\u003eOverall length of 9.0 inches for deep-reach measurement applications\u003c\/li\u003e\n  \u003cli\u003eRod diameter of 1\/8 inch (3.20 mm) for precise gage interface fit\u003c\/li\u003e\n  \u003cli\u003eSold individually for single-rod replacement or range expansion\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with STARRETT 440 Series Micrometer Depth Gages.

Ensure the depth gage is removed from service and the spindle is fully retracted before swapping rods. Handle the rod carefully to avoid surface damage that could affect measurement accuracy. Verify rod seating and zero calibration before returning the gage to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Rod\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 8 to 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 9.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 1\/8 inch (3.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 71981\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544575934770,"sku":"71981","price":43.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/932158764abe538430b853636daf4b73.jpg?v=1785930452","url":"https:\/\/voomisupply.com\/products\/starrett-71981-micrometer-rod-8-to-9-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
