Constructed from M35 cobalt high-speed steel, it offers improved heat and wear resistance compared to standard M2 HSS tooling, making it suited for harder workpiece materials and interrupted cuts. The bar accepts a minimum bore diameter of 0.75 inches and reaches a maximum bore depth of 3.75 inches, with a 0.75-inch shank diameter and an overall length of 5.5 inches. Machinists and tool-and-die professionals use this style of boring bar for achieving accurate bore dimensions and smooth finishes in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use in manual lathes and CNC turning applications where right-hand cutting direction is required. It is well-suited for through-boring and blind-bore operations on steel, stainless, cast iron, and other ferrous materials where cobalt tooling provides an advantage over standard HSS. The 0.75-inch shank is compatible with standard boring bar holders and tool posts sized for that shank diameter. It is typically installed by machinists, toolmakers, and skilled trade professionals performing precision bore work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM35 cobalt HSS construction for improved heat resistance and tool life over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for conventional lathe and turning center setup\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.75 inches suits a wide range of production bore sizes\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 3.75 inches accommodates deep-bore applications\u003c\/li\u003e\n\u003cli\u003e0.75-inch shank diameter fits standard boring bar holders and tool posts\u003c\/li\u003e\n\u003cli\u003e5.5-inch overall length provides adequate reach and rigidity in the tool post\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use boring bar compatible with tool posts and boring bar holders accepting a 0.75-inch round shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard lathe tooling setup procedures. Ensure the machine spindle is fully stopped and power is isolated before mounting or adjusting tooling. The bar should be clamped securely in the tool holder with minimal overhang beyond the holder to reduce chatter and deflection. Follow applicable shop safety standards and machine manufacturer guidelines when setting tool height and securing the shank.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Boring\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\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.62 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 375-5172\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707865366834,"sku":"375-5172","price":126.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0fd6ee0aa6187ee660ed850d9b7c1464.jpg?v=1788442601","url":"https:\/\/voomisupply.com\/products\/value-collection-375-5172-boring-bar-m35-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
