It accepts a minimum bore diameter of 9\/16 inches and reaches a maximum bore depth of 1-11\/16 inches, making it well suited for close-tolerance hole finishing in steel, stainless, and other ferrous materials where cobalt grades outperform standard HSS tooling. The 3\/4 inch shank diameter provides rigid tool holding in standard boring bar holders and turret toolposts. Overall length is 3-7\/16 inches. Machinists and toolroom operators will find this bar appropriate for production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is used in general metalworking applications where an internally bored hole must be brought to a precise diameter or finish. Typical installation scenarios include lathe turrets, manual boring mills, and CNC turning centers equipped with round-shank boring bar holders sized for 3\/4 inch tooling. The M35 cobalt grade offers improved heat and wear resistance compared to M2 HSS, making it a practical choice when cutting harder alloys or running without flood coolant. Right-hand cutting direction suits conventional lathe setups where the spindle runs in the standard forward rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt construction for improved heat resistance and tool life over standard HSS\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 9\/16 inches suits close-clearance internal boring work\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 1-11\/16 inches for moderate-depth holes without excessive overhang\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch shank diameter fits standard round-shank boring bar holders and turret toolposts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for conventional forward-spindle lathe operation\u003c\/li\u003e\n  \u003cli\u003eCompact 3-7\/16 inch overall length promotes rigidity and reduces chatter risk\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard addition for metalworking lathes and boring machines that accept 3\/4 inch round-shank boring bar tooling with right-hand cutting direction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist with the machine powered off and the spindle fully stopped before any tooling change. The shank should be clamped securely in a properly sized boring bar holder to minimize overhang and reduce the risk of chatter or tool deflection. Verify cutting edge height is set on centerline before beginning a boring pass. Always follow the machine manufacturer guidelines and applicable shop safety procedures when setting up and operating boring tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 9\/16 inches (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1-11\/16 inches (1.6875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: 375-5144\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694258880818,"sku":"375-5144","price":98.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d6dc1be402b7b19d8f3ff785ce5ac8c.jpg?v=1788322313","url":"https:\/\/voomisupply.com\/products\/value-collection-375-5144-boring-bar-m35-cobalt-3-4-inch-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
