It carries the full designation TCGW221S0630F 7025 and belongs to the CoroTurn 107 series. The insert features a triangular shape with a 60-degree included angle, a 1\/4-inch inscribed circle, and a 1\/64-inch (0.0157-inch) corner radius. The cutting edge receives an ER-treated negative land finish. Grade 7025 CBN is uncoated and suited for hard-turning applications where tight tolerances and surface finish are critical. Screw-on holding and a neutral hand orientation make it compatible with a wide range of CoroTurn 107 toolholders. Machinists and CNC operators working on hardened steel, cast iron, and similar H-group materials are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is designed for turning operations on hardened workpiece materials classified under ISO material group H, which includes hardened steels and hard cast irons. The CoroTurn 107 series is commonly used in CNC turning centers for finishing and semi-finishing passes where material hardness would degrade conventional carbide tooling. The maximum depth of cut is 1.80 mm (0.0709 inches), making this insert best suited for light, precise finishing cuts rather than heavy stock removal. It fits screw-on insert pockets on compatible CoroTurn 107 toolholders designed for TCGW-style inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCubic boron nitride (CBN) insert material for hard-turning of ISO H-group materials\u003c\/li\u003e\n\u003cli\u003eUncoated Grade 7025 with ER-treated negative land cutting edge for consistent edge integrity\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape (T) with 60-degree included angle and 7-degree relief angle\u003c\/li\u003e\n\u003cli\u003e1\/4-inch inscribed circle with 1\/64-inch corner radius for tight-tolerance finishing\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method with neutral hand orientation\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 1.80 mm (0.0709 inches) suited for finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in SANDVIK COROMANT CoroTurn 107 series toolholders that accept TCGW-style screw-on inserts with a 2.80 mm (0.1102-inch) hole diameter.

Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key for the insert clamping screw as specified by the toolholder manufacturer. Inspect the insert pocket and seating surface for chips or debris before seating the insert, and confirm correct torque per the toolholder documentation rather than estimated hand-feel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TCGW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull ISO Designation\u003c\/strong\u003e: TCGW110304S01530F7025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cubic Boron Nitride (CBN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 7025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (T)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0157 inches \/ 0.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 10.74 mm (0.4228 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3.18 mm (1\/8 inch \/ 0.1252 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 2.80 mm (0.1102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.80 mm (0.0709 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: ER Treated, Negative Land\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.53 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.58 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.74 inches\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: 6270099\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51730738970930,"sku":"6270099","price":170.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f1787693d780ffea884445e402df7eb.jpg?v=1788721998","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6270099-turning-insert-tcgw221s0630f-7025","provider":"Voomi Supply","version":"1.0","type":"link"}
