Carrying grade AC530U with a dual-layer PVD coating of AlCrN and TiAlN, this insert delivers thermal resistance and edge durability across a range of workpiece materials. The cutting width measures 0.0787 inches (2.00 mm) and the cutting height is 0.1417 inches (3.60 mm), making it suited for shallow, tight-tolerance groove profiles. It uses a screw-clamping insert holding method and ships as a double-ended, neutral-hand insert. Machinists and toolroom technicians select this insert for finishing and semi-finishing grooves where surface integrity and dimensional accuracy are critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in metal-cutting applications involving stainless steel and steel as primary workpiece materials. Secondary material compatibility includes cast iron, hard materials, non-ferrous metals, superalloys, and titanium. It fits GND series toolholders sized for the 2002 insert seat. The chip breaker geometry is GG, which is optimized for controlled chip formation during grooving passes. Typical installation environments include production turning cells and job shop lathes running ISO and ANSI-standard tooling systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with AC530U grade for wear resistance in ferrous and superalloy materials\u003c\/li\u003e\n  \u003cli\u003ePVD-applied AlCrN and TiAlN dual coating for thermal stability and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003e0.0787 inch (2.00 mm) cutting width with a 0.0079 inch (0.20 mm) corner radius for tight groove tolerances\u003c\/li\u003e\n  \u003cli\u003eDouble-ended neutral insert maximizes usable cutting edges per unit\u003c\/li\u003e\n  \u003cli\u003eGG chip breaker geometry promotes reliable chip evacuation during grooving passes\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp holding method provides positive insert seating and repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in GND series grooving toolholders with a size 2 insert seat.

Seat the insert fully in the pocket and torque the clamping screw to the toolholder manufacturer specification before running. Inspect the insert pocket and screw threads for debris or wear before seating a new insert. Never run a chipped or cracked insert, as carbide fracture during a cut presents a safety hazard.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GCM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: AC530U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlCrN and TiAlN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.0787 inches (2.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 0.1417 inches (3.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches (0.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.8307 inches (21.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 0.0787 inches (2.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\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\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: GND\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Superalloy, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 18HMALK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51755280073010,"sku":"18HMALK","price":43.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eec9d1ed96afcd3957e767019506893f_fc2b995d-5ad5-4da7-8410-0eb10ce7b6e1.jpg?v=1788953027","url":"https:\/\/voomisupply.com\/products\/sumitomo-18hmalk-grooving-insert-gcm2002gg-ac530u-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
