It is a square-shaped, single-sided insert with a 90-degree included angle, designed for face and shoulder milling operations on steel workpieces. The insert features a TiAlN coating applied via PVD process, which provides wear resistance and thermal stability during high-speed cutting. With four cutting edges, a positive rake geometry, and a honed cutting edge style, this insert delivers consistent performance in P15 to P30 material grade applications. Licensed HVAC techs will not be fitting this part  -  it is installed by machinists and CNC operators in metalworking environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel in both light and moderate stock-removal applications corresponding to ISO material group P, specifically P15 and P30 classifications. It fits into screw-type insert pockets and is compatible with Tungaloy cutter series EPO07, TPO07, and HPO07-M. The neutral hand orientation and positive rake make it adaptable to a range of face milling and square-shoulder milling setups in production and job-shop environments. The MJ chip breaker geometry is optimized for steel cutting with reliable chip control across a range of depths and feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with AH330 grade designation for steel milling applications\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating for improved wear resistance and extended tool life in P15-P30 steels\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert  -  maximizes value per insert over the tool life cycle\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry with honed cutting edge reduces cutting forces on the workpiece\u003c\/li\u003e\n  \u003cli\u003eMJ chip breaker provides controlled chip formation during steel milling operations\u003c\/li\u003e\n  \u003cli\u003eScrew-held, neutral-hand design for straightforward indexing in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with Tungaloy cutter series EPO07, TPO07, and HPO07-M.

Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Use the appropriate Torx or hex key to secure the clamping screw to the toolholder manufacturer's specification  -  do not overtighten. Inspect the insert pocket seating surface for chips or debris before seating a new insert to maintain proper edge geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SDMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AH330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\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\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.187 inches (3\/16 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1204\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P15, P30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: EPO07, TPO07, HPO07-M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: SDMT1204AFPN-MJ AH330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SDMT1204AFPN-MJ AH330\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: 0.015 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: 6806251\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51972089610546,"sku":"6806251","price":212.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1047eb323e723f6b1c32276be86962a4.jpg?v=1789962419","url":"https:\/\/voomisupply.com\/products\/tungaloy-6806251-sdmt1204afpn-mj-ah330-milling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
