It features a 3\/4 inch (19.05 mm) shank diameter and an overall length of 10 inches (254 mm), with a minimum bore diameter of 0.9291 inches (23.6 mm). The toolholder uses screw clamping to secure a single TCMT 221 insert and delivers a neutral rake angle with a 0-degree lead angle. Coolant-through capability supports chip evacuation and thermal management during deep bore applications. This bar is installed by machinists and CNC toolroom technicians working with tight-tolerance bore work.\u003c\/p\u003e\n\u003cp\u003eThe 5734147 is suited for residential machine shops, production facilities, and job shops requiring reliable internal boring and turning from a single toolholder. The E-STFC toolholder style and right-hand cut orientation make it a standard fit for conventional lathe setups. With a center-to-cutting-edge dimension of 0.5 inches (12.70 mm) and a neck diameter of 0.75 inches, this bar maintains rigidity in moderate-depth bore applications. Its multi-use designation allows both boring and turning operations without changing the toolholder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and vibration resistance in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design aids chip evacuation and heat management\u003c\/li\u003e\n  \u003cli\u003eScrew clamping insert retention provides repeatable, secure indexing\u003c\/li\u003e\n  \u003cli\u003eCompatible with TCMT 221 inserts with a 1\/4 inch (6.35 mm) inscribed circle\u003c\/li\u003e\n  \u003cli\u003eNeutral rake and 0-degree lead angle for balanced cutting forces\u003c\/li\u003e\n  \u003cli\u003eMulti-use toolholder supports both boring and turning operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TCMT 221 series inserts.

Ensure the machine spindle is fully stopped and locked out before mounting or changing the toolholder. Verify insert seating and screw torque per the insert manufacturer guidelines before initiating a cut. Confirm bore clearance and overhang ratio are within acceptable limits for the specific material and depth of cut to minimize chatter risk.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.9291 inches (23.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches (254 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TCMT 221\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw Clamping\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: E-STFC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Boring and Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.188 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5734147\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51742235066674,"sku":"5734147","price":1668.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/123bc9bd67ebf0db08bf19791889d689.jpg?v=1788836078","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5734147-indexable-boring-bar-3-4-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
