Built from steel with a 1-inch shank diameter, this right-hand toolholder reaches a minimum bore diameter of 1.2992 inches (33 mm) and runs an overall length of 12 inches (304.80 mm). It uses screw clamping to secure a single VBMT 332 insert with a 3\/8-inch inscribed circle. The neutral rake angle and 0-degree lead angle make this bar well suited for consistent material removal in boring, profiling, and turning passes. Coolant-through capability supports chip control and tool life in continuous cutting cycles.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for CNC lathes and turning centers in production machining environments. It handles boring, profiling, and turning operations in a single setup, reducing tool changes on multi-step internal features. The A-SVQB toolholder style and CoroTurn 107 series designation are standard references for machinists sourcing replacement or additional holders for existing insert programs. The 12-inch overall length provides reach for deeper bore work while the 1-inch neck diameter maintains rigidity along the bar length.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMinimum bore diameter of 1.2992 inches (33 mm) for internal machining access\u003c\/li\u003e\n\u003cli\u003eCoolant-through design aids chip evacuation and extends insert life\u003c\/li\u003e\n\u003cli\u003eScrew clamping insert retention for secure, repeatable positioning\u003c\/li\u003e\n\u003cli\u003eCompatible with VBMT 332 inserts featuring a 3\/8-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eMulti-use capability: boring, profiling, and turning in a single holder\u003c\/li\u003e\n\u003cli\u003eNeutral rake with 0-degree lead angle supports consistent cutting geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with VBMT 332 inserts as part of the SANDVIK COROMANT CoroTurn 107 series.

Verify insert and holder pairing against current CoroTurn 107 insert grade and geometry selections before ordering.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician on a CNC lathe or turning center. Power down and lock out the machine spindle before mounting or removing the toolholder. Confirm turret bore and shank fit before tightening, and follow the machine tool manufacturer torque specifications for the toolholder clamp screws. Do not exceed the minimum bore diameter rating, as insufficient clearance can cause insert contact with the workpiece wall.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A-SVQB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\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\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.2992 inches (33 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: 0.75 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: VBMT 332\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inch (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Boring, Profiling, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.27 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 12.21 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1.58 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 1.58 inches\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: 5721807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51754479550770,"sku":"5721807","price":368.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f04cf47ec8e572f8325c2ddfe34660ae.jpg?v=1788945836","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5721807-indexable-boring-bar-1-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
