Built to the CoroCut QD series specification, this insert features a 3.00 mm cutting width (0.1181 inches), a neutral lead angle of 0 degrees, and a 7-degree relief angle. The CL chipbreaker geometry promotes controlled chip evacuation in a range of workpiece materials. A PVD-applied TiCN\/Al2O3\/TiN coating improves wear resistance and surface finish quality. Machinists and tool-and-die shops use this insert for precision parting cuts in production turning environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for light to medium-duty cutoff and grooving applications on ferrous and non-ferrous materials. The QD insert style uses a clamp holding method, providing rigid, repeatable seating in compatible CoroCut QD toolholders and blade systems. The 0.30 mm corner radius (0.0118 inches) reduces stress concentration at the cutting edge, making it appropriate for finishing passes and close-tolerance parting operations. It is typically installed by CNC machinists and tool room technicians in precision machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.00 mm cutting width (0.1181 inches) for precise parting and grooving\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction with PVD-applied TiCN\/Al2O3\/TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eNeutral lead angle and 7-degree relief angle support clean, consistent cuts\u003c\/li\u003e\n\u003cli\u003eCL chipbreaker geometry promotes controlled chip flow during cutoff operations\u003c\/li\u003e\n\u003cli\u003e0.30 mm corner radius (0.0118 inches) reduces edge stress on finishing passes\u003c\/li\u003e\n\u003cli\u003eClamp holding method ensures rigid, repeatable insert seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CoroCut QD series toolholders and blade systems that accept G-seat inserts with the QD insert style.

Power down and lock out the machine before changing inserts. Use the correct torque wrench for the clamp screw as specified by the toolholder manufacturer — do not overtighten, as this can crack the carbide insert. Inspect the insert seat and clamping surfaces for chips or debris before seating the new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1135\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\/Al2O3\/TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0 degrees, Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7.00 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.30 mm (0.0118 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: QD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroCut QD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 6398177\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51745789477170,"sku":"6398177","price":389.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/419d1cc1390e9eed4d11875cf6eb8cfc.jpg?v=1788865184","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6398177-cutoff-insert-3mm-corocut-qd","provider":"Voomi Supply","version":"1.0","type":"link"}
