The set covers a minimum bore diameter range of 0.25 inches on the smallest bar up to 0.5 inches on the largest bar, with maximum bore depths ranging from 0.75 inches to 2.5 inches across the set. Overall lengths span 2-1\/8 inches to 3-7\/8 inches, and all bars share a common 0.5-inch shank diameter. The right-hand cutting direction and bright uncoated finish make these bars suited for machinists working in ferrous and non-ferrous materials where cobalt-grade tooling is preferred for heat and wear resistance.\u003c\/p\u003e\n\u003cp\u003eThis boring bar set is intended for use in machine shop environments handling precision internal diameter work. The graduated size range across 10 bars allows a machinist to match the appropriate bar to a specific bore requirement without changing shank holders. Typical applications include boring bearing pockets, bushing seats, and precision through-holes in production or toolroom settings. The included wood stand keeps bars organized and protects cutting edges between uses.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt steel construction for improved heat resistance and edge retention over standard HSS\u003c\/li\u003e\n  \u003cli\u003e10-piece set covering minimum bore diameters from 1\/4 inch to 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth range from 3\/4 inch to 2-1\/2 inch across the set\u003c\/li\u003e\n  \u003cli\u003eUniform 1\/2-inch shank diameter throughout the set for consistent tool holder setup\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut configuration for standard lathe and boring mill operation\u003c\/li\u003e\n  \u003cli\u003eWood storage stand included to protect cutting edges and keep the set organized\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in tool holders accepting a 1\/2-inch round shank boring bar, common on engine lathes, turret lathes, and small horizontal boring mills in production and toolroom settings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. The machine spindle must be fully stopped and locked out before setting or adjusting boring bars in the tool holder. Bar overhang should be minimized to reduce chatter; extend only as far as the bore depth requires. Follow the machine manufacturer's tool-holding torque guidelines and verify bar runout before taking a finishing cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M35 Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter - Smallest Bar\u003c\/strong\u003e: 1\/4 inch (0.25 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter - Largest Bar\u003c\/strong\u003e: 1\/2 inch (0.50 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth - Smallest Bar\u003c\/strong\u003e: 3\/4 inch (0.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth - Largest Bar\u003c\/strong\u003e: 2-1\/2 inches (2.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Overall Length\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Overall Length\u003c\/strong\u003e: 3-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStand Material\u003c\/strong\u003e: Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.31 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 375-1207\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690286612786,"sku":"375-1207","price":320.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e6fa65f5a8373f0064788a03e209797.jpg?v=1788268159","url":"https:\/\/voomisupply.com\/products\/value-collection-375-1207-boring-bar-set-10-piece-m35-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
