It is an uncoated, fine-grain carbide insert in a square shape with a neutral hand orientation, designed for use in indexable milling cutters. The insert features a positive rake angle of 18 degrees, a 20-degree relief angle, and a honed cutting edge style. With four usable cutting edges and a corner radius of 0.0394 inches, it delivers consistent performance in finish and semi-finish milling operations. The E07 chip breaker geometry and bright uncoated surface suit applications where coating-induced edge buildup is a concern.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for milling non-ferrous metals as its primary workpiece material, with secondary suitability for cast iron, superalloys, and titanium. It fits the SECO R220.13-12 cutter series and is compatible with wedge-clamp insert holding systems. Typical applications include face milling, shoulder milling, and profile milling operations performed by machining professionals in manufacturing, aerospace, and job-shop environments. The uncoated HX grade and fine-grain substrate make it particularly effective when sharp edge retention and low cutting forces are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide fine-grain substrate in uncoated HX manufacturer grade for sharp, stable edges\u003c\/li\u003e\n  \u003cli\u003eSquare SEKR insert shape with four cutting edges per insert for extended tooling economy\u003c\/li\u003e\n  \u003cli\u003ePositive rake (18 degrees) and 20-degree relief angle reduce cutting forces on non-ferrous and superalloy workpieces\u003c\/li\u003e\n  \u003cli\u003eE07 chip breaker geometry controls chip flow in finish and semi-finish milling passes\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.3465 inches with an effective cutting edge length of 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible mounting in compatible cutter bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the SECO R220.13-12 cutter series using wedge-clamp insert holding.

Power down and lock out the machine spindle before seating or indexing inserts. Wedge-clamp systems require proper torque on the clamping wedge per the cutter body manufacturer specifications — do not use the insert torque values for the clamping fastener interchangeably. Inspect the cutter pocket seat for chips or debris before seating a new insert to ensure full contact and prevent insert rocking under load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SEKR\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: HX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide, Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1252 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0394 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3465 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 18 degrees, Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: E07\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Wedge Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R220.13-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1203\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SEKR-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: SEKR1203AFN-E07\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74016343\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561924264242,"sku":"74016343","price":244.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f899ec8551c60985af998e7f6ff46b85.jpg?v=1786470077","url":"https:\/\/voomisupply.com\/products\/seco-74016343-milling-insert-sekr1203afn-e07-hx-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
