Manufactured to the ANSI and ISO code TOMT100408PDER-MJ AH120, it carries a TiAlN coating applied via PVD process, delivering thermal resistance and wear protection across demanding cutting conditions. The insert features a positive rake geometry with a honed cutting edge, a corner radius of 0.0315 inches (1\/32 inch), and supports a maximum depth of cut of 0.3940 inches (10.00 mm). Three cutting edges and a right-hand orientation make this a productive option for production machining environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for milling steel, stainless steel, cast iron, hard materials, superalloys, and titanium, covering material grades P15, M15, K15, and S10. It is appropriate for use in both roughing and semi-finishing applications where tool life and edge stability are priorities. The MJ chip breaker geometry is optimized for chip control across this broad range of workpiece materials. Installation is typically performed by machining professionals in production or job-shop settings using compatible toolholders from the EPA10, TPA10, TLA10, HPA10-M, and C-EPA cutter series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN PVD coating in manufacturer grade AH120 for extended tool life in high-temperature cuts\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape (TOMT style) with 60-degree included angle and positive rake\u003c\/li\u003e\n\u003cli\u003eThree right-hand cutting edges per insert for cost-effective edge utilization\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style reduces microchipping on entry and exit\u003c\/li\u003e\n\u003cli\u003eMJ chip breaker provides reliable chip control across steel, cast iron, and superalloy applications\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.3940 inches supports aggressive material removal rates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with EPA10, TPA10, TLA10, HPA10-M, and C-EPA cutter series toolholders.

Use the appropriate Torx or hex key as specified by the toolholder manufacturer to secure the clamping screw to the correct seating torque. Inspect the insert pocket and seating surfaces for chips or debris before placing the insert. Never mix insert grades or geometries within a multi-pocket cutter body on the same operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TOMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\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: AH120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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 Size Code\u003c\/strong\u003e: 100408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: TOMT100408PDER-MJ AH120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MJ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3390 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1850 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.4130 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.4130 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3940 inches (10.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P15, M15, K15, S10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 6999179\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":52063690129714,"sku":"6999179","price":277.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/434be30ebc9e33f56b58c63f0453ba5e_96c4651f-6a14-4cde-95d6-b9937cecbe9d.jpg?v=1790043542","url":"https:\/\/voomisupply.com\/products\/tungaloy-6999179-tomt-triangle-milling-insert-ah120","provider":"Voomi Supply","version":"1.0","type":"link"}
