Manufactured to GCMN2002GG geometry with a CVD-applied AC830P coating, this double-ended insert delivers a 2 mm cutting width and a maximum depth of cut of 0.75 inches (19.05 mm). The neutral hand orientation suits straight plunge grooving applications. With a positive rake angle of 5 degrees and a GG chip breaker, it is engineered for consistent chip control in demanding machining environments. Installation and tool management are handled by machinists and CNC operators working with compatible grooving toolholders.\u003c\/p\u003e\n\u003cp\u003eThe 18RBALK targets external grooving and profiling operations in materials classified under ISO P and ISO M workpiece groups, specifically carbon and alloy steels and stainless steels. The GCMN insert style and 2002 size code make it a direct fit for GND-series toolholders requiring a size-2 insert seat. The GG chip breaker geometry is suited to moderate feed rates and finish grooving passes where controlled chip evacuation reduces surface damage risk. This insert is sold individually and typically ordered in multiples of five to maintain toolcrib inventory at active turning cells.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied AC830P coating for wear and heat resistance in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e2 mm cutting width (0.0787 inches) with a maximum depth of cut of 19.05 mm (0.75 inches)\u003c\/li\u003e\n  \u003cli\u003eDouble-ended insert design provides two cutting edges per insert, extending tool life\u003c\/li\u003e\n  \u003cli\u003eGG chip breaker with positive 5-degree rake angle for effective chip control in grooving operations\u003c\/li\u003e\n  \u003cli\u003e0.20 mm (0.0079 inch) corner radius for clean groove floor geometry\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO 13399 standards for tooling data interoperability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with GND-series grooving toolholders accepting a size-2 insert seat and GCMN-style inserts.

Power down and lock out the machine spindle before seating or removing the insert. Secure the insert firmly in the toolholder pocket using the appropriate torque wrench per the toolholder manufacturer specification before resuming cuts. Inspect the insert seat and clamping hardware for debris or wear each time an edge is indexed to the next position.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GCMN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC830P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 2.00 mm (0.0787 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 19.05 mm (0.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 10.00 mm to 20.00 mm (0.30 to 1.00 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0079 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 3.61 mm (0.1420 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.8310 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 2.00 mm (0.0787 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 21.11 mm (0.8310 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees (Positive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: GND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel (ISO M, ISO P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: GCMN2002-GG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Standard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 18RBALK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51744843006258,"sku":"18RBALK","price":171.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/951d2ff456a2ceebfb0da99bf661d8f0_797a4cb9-3c6e-48e1-bd33-55b4a9fbee09.jpg?v=1788861396","url":"https:\/\/voomisupply.com\/products\/sumitomo-18rbalk-grooving-insert-ac830p-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
