Manufactured to the ACK300 grade with a PVD coating process, this insert delivers wear resistance and edge stability when cutting cast iron workpieces. The parallelogram insert shape (AXMT style) features an 85-degree included angle and an 11-degree relief angle, supporting a maximum depth of cut of 0.551 inches. At 0.138 inches thick and with a cutting edge effective length of 0.689 inches, this insert is sized for precision stock removal in demanding machining environments. Installation is handled by machinists and tooling technicians as part of a cutter body setup.\u003c\/p\u003e\u003cp\u003eThis insert is intended for milling applications where cast iron is the primary workpiece material, corresponding to ISO material group K. The right-hand cutting configuration suits standard right-hand cutter body orientations. The G chip breaker geometry promotes controlled chip evacuation during moderate to aggressive feed rates. Typical use cases include face milling, shoulder milling, and profile milling on cast iron components in production or job shop environments. The ACK300 grade with PVD coating is suited to dry or semi-dry cutting conditions common in cast iron machining.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eACK300 manufacturer grade with PVD coating for wear resistance in cast iron cutting\u003c\/li\u003e\n\u003cli\u003eAXMT insert style with parallelogram shape and 85-degree included angle\u003c\/li\u003e\n\u003cli\u003e11-degree relief angle reduces cutting forces and supports clean edge engagement\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.551 inches with a cutting edge effective length of 0.689 inches\u003c\/li\u003e\n\u003cli\u003eG chip breaker geometry for controlled chip formation and evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand insert orientation for standard cutter body compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement milling insert for right-hand cutter bodies accepting AXMT-style parallelogram inserts with insert size code 1235.

Ensure the machine spindle is fully stopped and locked out before seating or replacing inserts. Use the correct torque wrench and insert screw specified by the cutter body manufacturer — do not over-tighten the clamp screw. Inspect the insert pocket seat for debris or damage before placing the new insert to ensure proper seating and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: AXMT\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: Coated (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACK300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 85 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1235\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.138 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.689 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.551 inches (14.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO Code K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14HD320\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51750579437874,"sku":"14HD320","price":223.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/583cad4ba92f1ba74dc5ab41cfbf49eb_5d18de97-79e6-4d1c-89a1-1bf4d8da8152.jpg?v=1788916933","url":"https:\/\/voomisupply.com\/products\/sumitomo-14hd320-milling-insert-ack300-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
