It covers a minimum measurement range starting at 25 mm and delivers an accuracy of 0.006 mm, making it suitable for tight-tolerance work on bores, slots, and recesses. The measuring faces are solid carbide for wear resistance. A satin chrome finish reduces glare and corrosion. This instrument is used by machinists, tool-and-die makers, metrologists, and precision-measurement technicians on the shop floor or in the inspection room.\u003c\/p\u003e\u003cp\u003eThe 145-186 is well suited for inside-diameter measurements in precision manufacturing environments, both in job shops and production facilities. It is appropriate for inspection of machined bores, turned components, and ground features where consistent, repeatable measurement is required. Note that a setting standard is required to accurately set the micrometer to the reference point before use; one is not included with this instrument.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide measuring faces for extended wear life in high-use shop environments\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.006 mm for tight-tolerance measurement tasks\u003c\/li\u003e\n\u003cli\u003eSatin chrome finish reduces surface glare and resists corrosion\u003c\/li\u003e\n\u003cli\u003eMechanical analog operation requires no battery or calibration of electronics\u003c\/li\u003e\n\u003cli\u003eA setting standard is required for reference-point setup prior to measurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a precision inside measurement instrument for use in standard metrology and quality-control workflows where a setting standard is available for reference setup.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis instrument is handled and operated by machinists, metrologists, or quality-control technicians. Before use, set the micrometer to the reference point using an appropriate setting standard as required by the design of this tool. Keep the measuring faces clean and free of chips, coolant, and debris before each measurement. Store the instrument in its case away from temperature extremes to maintain calibration stability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Measurement Range\u003c\/strong\u003e: 25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.006 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDigital Counter\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetting Standard Included\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITUTOYO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 145-186\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51562342318386,"sku":"145-186","price":355.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9f258b693b6dd8acc18dd674a8b9237.jpg?v=1786475328","url":"https:\/\/voomisupply.com\/products\/mitutoyo-145-186-mechanical-caliper-micrometer-25mm","provider":"Voomi Supply","version":"1.0","type":"link"}
