With a minimum bore diameter of 0.5 inches and a maximum bore depth of 2.5 inches, it handles a wide range of small to mid-size bore applications. The 0.75-inch shank diameter provides rigid tool holding in standard boring bar holders. Overall length is 4.25 inches. M35 cobalt grade offers improved heat and wear resistance compared to standard high-speed steel, making it suitable for harder workpiece materials and interrupted cuts.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for manual and CNC lathes in job shop, production, and maintenance machining environments. It is used when opening existing holes to precise diameters, correcting bore geometry, or finishing cast, forged, or pre-drilled workpieces. The right-hand cutting direction is the standard orientation for conventional lathe operation with the spindle rotating counterclockwise when viewed from the tailstock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\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 0.5 inches for small-bore applications\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 2.5 inches handles most short to mid-length bores\u003c\/li\u003e\n\u003cli\u003e0.75-inch shank diameter fits standard boring bar tool holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for conventional lathe setups\u003c\/li\u003e\n\u003cli\u003eCompact 4.25-inch overall length reduces overhang and chatter risk\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 0.75-inch boring bar holders on manual and CNC lathes configured for right-hand tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Secure the shank firmly in the tool holder with minimal overhang to reduce deflection and chatter. Power down and lock out the machine before mounting or adjusting tooling. Verify bore diameter and depth settings against the workpiece drawing before beginning the cut.\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\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 2.5 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: 4.25 inches\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: 1 pound\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: 375-5140\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689366389042,"sku":"375-5140","price":106.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ddfd9f6b45522066830923c40bf626c.jpg?v=1788258355","url":"https:\/\/voomisupply.com\/products\/value-collection-375-5140-boring-bar-m35-cobalt-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
