Built from steel with a 1-inch shank diameter and a 12-inch overall length, this right-hand toolholder accepts TCMT 32.52 inserts secured by screw clamping. The minimum bore diameter is 1.2008 inches (30.50 mm), making it suitable for moderate to large bore work. Coolant-through capability supports chip evacuation and tool life in continuous cuts. The neutral rake geometry and 0-degree lead angle provide predictable, stable cutting performance across a range of materials.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in production and job-shop turning applications where consistent bore geometry and insert repeatability are required. It is suited for both roughing and finishing passes on internal diameters starting at 1.2008 inches. The A-STFC toolholder style supports multi-use configurations, allowing the same bar to be used for boring and turning setups without changing the holder. It is installed by machinists and CNC tooling technicians in shops running steel, cast iron, and similar workpiece materials on engine lathes or CNC turning centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCoroTurn 107 series A-STFC style holder with screw clamping for positive insert retention\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 1.2008 inches (30.50 mm) for mid-range and larger bore applications\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip flushing and extended insert life in continuous cuts\u003c\/li\u003e\n\u003cli\u003eNeutral rake (0-degree rake angle, 0-degree lead angle) for predictable cutting geometry\u003c\/li\u003e\n\u003cli\u003eMulti-use application: compatible with both boring and turning setups\u003c\/li\u003e\n\u003cli\u003eSteel construction with 1-inch shank diameter and 12-inch overall length for rigid overhang support\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with TCMT 32.52 inserts (1\/4-inch inscribed circle, 5\/32-inch thickness).

Verify insert grade and geometry selection against workpiece material requirements before use.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Secure the shank in the turret or boring bar holder to the tool manufacturers recommended clamping torque using calibrated tooling. Power down and lock out the machine spindle before inserting or changing the toolholder. Confirm insert seating and screw torque prior to taking any cut; a loose insert under load is a safety hazard and will damage the pocket.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A-STFC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.2008 inches (30.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches (304.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.6400 inches (16.26 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TCMT 32.52\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1563 inches (5\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw Clamping\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\u003eMulti-Use Application\u003c\/strong\u003e: Boring, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Inserts Used\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 12.13 inches L x 1.42 inches W x 1.42 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.27 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: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5721800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51727178367282,"sku":"5721800","price":366.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4712c31fca6b847369c4a1e1358bba86.jpg?v=1788674370","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5721800-indexable-boring-bar-1-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
