Built to the GCMN3002-GL insert style with a manufacturer grade of AC520U, this double-ended insert features a 3.00 mm cutting width and a maximum depth of cut of 19.05 mm (0.7500 inches). The PVD coating process delivers a hard, wear-resistant surface layer suited for demanding metal removal applications. A positive rake angle of 5 degrees and the GL chip breaker geometry support controlled chip evacuation and reduced cutting forces across a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is appropriate for universal workpiece material classifications covering steel (P), stainless and heat-resistant alloys (M), cast iron (K), and superalloys (S), making it a versatile choice for job shops and production turning environments. It fits GND series toolholders and is compatible with insert seat size 3. The neutral hand orientation suits straight-cut grooving setups where lateral force direction is not a variable. Typical applications include groove turning, parting, and face grooving operations where consistent width and depth accuracy are required across multiple passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC520U PVD-coated solid carbide grade for extended tool life across multiple material groups\u003c\/li\u003e\n  \u003cli\u003e3.00 mm cutting width with a 19.05 mm maximum depth of cut for medium-depth groove work\u003c\/li\u003e\n  \u003cli\u003eGL chip breaker geometry promotes positive chip control and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eDouble-ended design provides two usable cutting edges per insert, improving cost efficiency\u003c\/li\u003e\n  \u003cli\u003ePositive 5-degree rake angle lowers cutting forces and supports stable machining at moderate feeds\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 insert seat size 3 and the GCMN insert style.

Ensure the insert pocket and seating surface are clean and free of chips or debris before seating the insert to prevent micro-fractures from uneven clamping load. Follow the toolholder manufacturer torque specifications for the clamping screw — do not over-torque. Verify insert orientation and confirm depth-of-cut parameters in the control program before resuming spindle operation.\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\u003eANSI Code\u003c\/strong\u003e: GCMN3002-GL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: GND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC520U\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: Coated (PVD)\u003c\/li\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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 19.05 mm (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 10.00 mm to 20.00 mm (0.3000 to 1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 3.81 mm (0.1500 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\u003eOverall Length\u003c\/strong\u003e: 0.8310 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\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: GL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: K, M, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\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: 18HWALR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51738665877810,"sku":"18HWALR","price":180.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e22fa97b01f548770cbc24ad2475af3_be373e70-7e29-48d4-ad77-8163b64c8953.jpg?v=1788802513","url":"https:\/\/voomisupply.com\/products\/sumitomo-18hwalr-grooving-insert-ac520u-3mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
