Carrying the ANSI\/ISO designation 218.19-160-04-E07, this insert features a positive rake angle of 20 degrees and a relief angle of 12 degrees, enabling clean cutting action with reduced cutting forces. The H25 grade micrograin solid carbide substrate is left uncoated, making it well-suited for applications where coating adhesion or thermal reactivity is a concern. The E07 chip breaker geometry promotes efficient chip evacuation during milling operations on non-ferrous metals and superalloys.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in face milling, shoulder milling, and similar indexed milling operations on non-ferrous metals such as aluminum, copper, and brass, as well as superalloys and titanium. The neutral hand orientation allows flexible mounting. It is sold individually but carries a minimum order quantity of 10 units. Typical users include CNC machinists and toolroom professionals working with precision milling cutters in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTrigon (triangle, 60-degree included angle) insert shape with 3 cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eH25 micrograin solid carbide grade, uncoated (bright finish) for non-ferrous and superalloy cutting\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (20 degrees) and 12-degree relief angle reduce cutting forces and heat generation\u003c\/li\u003e\n  \u003cli\u003eE07 chip breaker geometry supports controlled chip flow and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style improves edge toughness and surface finish consistency\u003c\/li\u003e\n  \u003cli\u003eSingle-sided insert with screw holding method; neutral hand orientation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with SECO cutter series R218.19-32, R217.21-R160, and R220.21-R160 as stated by the manufacturer.

Ensure the milling cutter body is fully de-energized and spindle is locked before replacing inserts. Use the appropriate Torx or hex key to seat the insert screw to the cutter body specification; do not over-torque the clamping screw. Inspect the cutter pocket and seating surface for chips or damage before installing a new insert to ensure proper seating and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 218.19\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: 218.19-160-04-E07\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (Triangle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 160-04\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: H25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 12 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\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: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: E07\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1874 inches (3\/16 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle Diameter\u003c\/strong\u003e: 0.4402 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0472 inches (3\/64 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1575 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0790 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConvex Radius\u003c\/strong\u003e: 0.6299 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal (N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium (S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02439321\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557944000818,"sku":"02439321","price":375.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5357fc89b2127555c1b40920979d0746.jpg?v=1786399065","url":"https:\/\/voomisupply.com\/products\/seco-02439321-trigon-milling-insert-h25-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
