It carries a 1\/4 inch diameter with a 0.0322 inch corner radius and a 0.0140 inch length of cut. The AlTiN coating improves thermal resistance and wear performance, making this tool well suited for harder workpiece materials and higher cutting speeds. With four straight flutes and right-hand cutting direction, it produces consistent finishes in short-cut applications. This tool is intended for installation and use by machinists and CNC tooling professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill belongs to the SECO SN400R series and is built for short-reach, high-precision milling where corner protection and surface finish are priorities. The extended reach design, with a 1-1\/4 inch reach length and 0.218 inch neck diameter, allows access into pockets and features where standard tools cannot reach. The cylindrical shank accepts standard 1\/4 inch collet holders. This tool is not center-cutting and is not intended for plunge entry. It is suited for side milling, profiling, and finishing passes on hardened or abrasive materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0322 inch corner radius protects edge integrity and reduces chipping on profiled cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides elevated heat and wear resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction delivers rigidity and edge sharpness\u003c\/li\u003e\n\u003cli\u003eExtended reach geometry with 1-1\/4 inch reach and 0.218 inch neck diameter for pocket access\u003c\/li\u003e\n\u003cli\u003eFour straight flutes with right-hand cutting direction for consistent chip formation\u003c\/li\u003e\n\u003cli\u003eSingle-end, cylindrical shank fits standard 1\/4 inch collet toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement-grade solid carbide end mill for use in CNC machining centers and manual mills accepting 1\/4 inch cylindrical shank toolholders.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into a clean, undamaged collet or end mill holder and torque the retention nut to the toolholder specification. This tool is not center-cutting — do not use for plunge or axial entry cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0322 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.0140 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.218 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SN400R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03043600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563811438898,"sku":"03043600","price":239.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40724cf512a571cb979c3aee8514c2b3_9529d0f4-7374-46ac-92b0-145055b825b7.jpg?v=1786503983","url":"https:\/\/voomisupply.com\/products\/seco-03043600-corner-radius-end-mill-1-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
