With a 0.157-inch shank diameter and an overall length of 1.073 inches, this is a compact tooling solution suited for small-bore applications on lathes, machining centers, and CNC turning equipment. Machinists and tooling specialists working with fine-tolerance bores rely on boring bars of this type to achieve accurate diameter and surface finish in production and job-shop environments. The part ships individually and is available in single-unit quantities.\u003c\/p\u003e\u003cp\u003eThis boring bar is applicable in precision metal-cutting operations where small shank diameters are required. It is suited for use in CNC turning centers, Swiss-type lathes, and multi-axis machining platforms handling small-diameter internal features. Typical users include machinists, toolroom technicians, and production shops working with ferrous and non-ferrous materials requiring controlled bore geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCompact 4.00 mm (0.157-inch) shank diameter for small-bore internal machining\u003c\/li\u003e\n\u003cli\u003e27.25 mm (1.073-inch) overall length provides a minimal footprint in tight tooling setups\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.04 pounds, minimizing spindle load in sensitive applications\u003c\/li\u003e\n\u003cli\u003eSingle-unit packaging supports individual replacement without excess inventory\u003c\/li\u003e\n\u003cli\u003eUNSPSC Code 23241601 classification for procurement and catalog integration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement boring bar for small-shank internal machining toolholders and systems accepting a 4.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of boring bars should be performed by a qualified machinist or tooling technician with the machine powered down and locked out per applicable safety procedures. Ensure the shank is fully seated and secured in the toolholder before resuming operation. Verify bore alignment and runout with a dial indicator before taking a finish pass. Follow the machine tool manufacturer guidelines for maximum overhang and cutting parameters for this shank diameter class.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm (0.157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 27.25 mm (1.073 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7968157\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51744949338418,"sku":"7968157","price":82.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44e59c60cc9a8cf220f3588a5d4036af_0a09d49d-cb69-4693-9ea0-40ceb1910f21.jpg?v=1788862588","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7968157-boring-bar-4-00mm-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
