The gage spans a range of 1\/2 to 3\/4 inch and features a 12-inch overall length handle, giving the technician reach into deeper bores and blind holes. The handle is constructed from hardened tool steel with a satin chrome finish for corrosion resistance and durability in shop environments. Machinists, tool-and-die workers, and maintenance technicians use this type of gage during precision bore inspection and engine or pump rebuilds.\u003c\/p\u003e\u003cp\u003eThis telescoping gage is suited for precision measurement tasks in machine shops, maintenance facilities, and production environments. It is used wherever a direct-reading bore gage is not available and an indirect transfer measurement to a micrometer is the preferred method. The 12-inch handle length makes it practical for measuring bores in deep housings, cylinders, and pump bodies where shorter gages cannot reach the measurement zone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range of 1\/2 to 3\/4 inch for small-bore applications\u003c\/li\u003e\n\u003cli\u003e12-inch overall handle length provides reach into deep or recessed bores\u003c\/li\u003e\n\u003cli\u003eHardened tool steel construction for long service life under repeated use\u003c\/li\u003e\n\u003cli\u003eSatin chrome finish resists corrosion and reduces glare during use\u003c\/li\u003e\n\u003cli\u003eSpring-loaded plungers lock in position for accurate transfer measurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard telescoping gage for use with outside micrometers and calipers capable of reading in the 1\/2 to 3\/4 inch range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTelescoping gages are installed by a machinist or precision measurement technician and require no permanent mounting or wiring. Compress the plungers, insert the gage into the bore at a slight angle, allow the plungers to extend, lock the knurled knob, then withdraw and measure across the plunger tips with a calibrated micrometer. Keep the gage clean and lightly oiled when stored to preserve the finish and prevent corrosion on the contact surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 1\/2 to 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Material\u003c\/strong\u003e: Hardened Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 15-446-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698087395634,"sku":"15-446-8","price":88.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f568cadc3506de2c538b7e6d9b7019b.jpg?v=1788357555","url":"https:\/\/voomisupply.com\/products\/spi-15-446-8-telescoping-gage-1-2-to-3-4-in-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
