It features a left-hand cut orientation with a -5 degree lead angle and a neutral rake angle of 0 degrees. The shank measures 1\/2 inch in diameter with an overall length of 8 inches, and the minimum bore diameter is 0.5984 inches. Insert retention uses a screw-clamp holding method, providing rigid clamping for consistent depth-of-cut control. Coolant-through capability is built in, supporting chip evacuation and tool life in deep-bore applications. This bar is installed by machinists and CNC operators in precision turning environments.\u003c\/p\u003e\u003cp\u003eThis boring bar suits internal diameter finishing and semi-finishing in small-bore applications where bore entry clearance is tight. The 0.5984-inch minimum bore diameter makes it appropriate for close-tolerance bore work in production and job-shop settings. The multi-use designation allows it to transition between turning applications without tool changes. It is engineered for use with CCMT 06 02 04 inserts, which are a standard size stocked by most industrial tooling suppliers. The CoroTurn 107 series is a recognized toolholder family used across a broad range of material types and cut depths in CNC turning.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity in small-diameter boring operations\u003c\/li\u003e\n\u003cli\u003eLeft-hand cut with -5 degree lead angle for specific approach requirements\u003c\/li\u003e\n\u003cli\u003eCoolant-through design for chip evacuation in deep or blind bores\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert retention for repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003eNeutral rake angle (0 degrees) for compatibility across a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eMulti-use tool designation supports varied internal turning applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts CCMT 06 02 04 inserts.

Disengage the machine spindle and confirm the turret is fully indexed and locked before mounting or removing the boring bar. Use the correct torque driver for the insert screw to avoid stripping the clamping mechanism — refer to the SANDVIK COROMANT insert tightening specification sheet for this series. Verify coolant-through passages are clear and aligned with the machine coolant supply before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.5984 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Neutral)\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: CCMT 06 02 04\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8.19 inches (L) x 1.18 inches (W) x 1.18 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.76 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: 5853217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51733470871858,"sku":"5853217","price":940.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/478668b0500ad0a3e13d3d9d506ab881.jpg?v=1788755706","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5853217-indexable-boring-bar-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
