It carries the ISO designation ETX4-040 and is finished with a TiAlN coating applied via PVD process, providing thermal resistance and extended tool life in demanding cutting environments. The insert has a cutting width of 0.157 inches (4.00 mm) and a corner radius of 0.016 inches (0.40 mm). It is screw-held and configured for right-hand cutting. Machinists and CNC tooling technicians install this insert in compatible EasyMcut toolholders for high-repeatability grooving work on steel and stainless steel components.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving operations on stainless steel and carbon steel as primary workpiece materials, with secondary application on cast iron. The AH725 grade combined with TiAlN coating makes it appropriate for both wet and dry cutting conditions where edge wear resistance is a priority. It fits production turning environments in job shops and manufacturing facilities where consistent groove geometry and tight tolerances are required. The screw-clamping method supports fast insert indexing without disturbing the toolholder setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD TiAlN coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eCutting width of 0.157 inches (4.00 mm) for precise groove sizing\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.016 inches (0.40 mm) for controlled corner geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand configuration with screw-holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eMulti-use capable insert per manufacturer designation\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards for system integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in EasyMcut series grooving toolholders that accept the ETX4-040 insert style and size code 4-040.

The machine spindle must be fully stopped and the turret or toolpost locked before seating or removing the insert. Use the manufacturer-specified torx or hex key to tighten the clamping screw  -  do not overtighten or substitute fasteners. Inspect the insert pocket and seating surface for chips or debris before each insert change to ensure accurate positioning and prevent insert rocking.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.157 inches (4.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.016 inches (0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.315 inches (8.00 mm)\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: AH725\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: ETX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 4-040\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EasyMcut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel (ISO codes M, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO code K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: ETX4-040\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.004 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: TUNGALOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6991279\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51963694481714,"sku":"6991279","price":37.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b1262676d3ce325e60f99c5cf8b2554.jpg?v=1789948581","url":"https:\/\/voomisupply.com\/products\/tungaloy-6991279-grooving-insert-ah725-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
