It features a 1 inch shank diameter, a minimum bore diameter of 1.2008 inches, and an overall length of 12 inches. The left-hand cut orientation and -1 degree lead angle suit specific approach and clearance requirements in bore finishing and semi-finishing applications. Insert retention is handled by a screw-clamp holding method, and the tool is coolant-through capable, supporting chip evacuation and tool life in deeper bore applications. A neutral rake angle of 0 degrees pairs with TCMT 16 T3 08 inserts.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for machinists and tooling specialists performing internal diameter turning in production or job-shop environments. It fits applications where a left-hand holder is required due to spindle rotation, tool path direction, or interference constraints. The CoroTurn 107 series is suited for both roughing and finishing passes in steel, cast iron, and similar materials. The coolant-through design makes it well suited for blind bore work where flushing chips from the cutting zone is critical to surface finish and insert life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cut orientation with -1 degree lead angle for specific bore approach geometry\u003c\/li\u003e\n\u003cli\u003eCoolant-through capability supports chip evacuation and extended insert life in deep bores\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method provides secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eUses TCMT 16 T3 08 inserts — a widely available insert geometry in the CoroTurn 107 platform\u003c\/li\u003e\n\u003cli\u003eSteel shank construction with neutral rake for versatile material application\u003c\/li\u003e\n\u003cli\u003eCenter to cutting edge dimension of 0.64 inches for tool-path and clearance planning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept TCMT 16 T3 08 inserts as specified for the CoroTurn 107 series.

Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before mounting or adjusting the boring bar. Confirm shank clamping torque and insert screw torque per the toolholder manufacturer documentation provided with the assembly. Verify bore clearance against the 1.2008 inch minimum bore diameter before entry to prevent interference damage to the insert or workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.2008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -1 degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Neutral)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TCMT 16 T3 08\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.27 pounds\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: 5721799\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728293888306,"sku":"5721799","price":349.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f9d7eac89b155e9f11a84c33c1bed56.jpg?v=1788690303","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5721799-indexable-boring-bar-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
