It features a 5\/16-inch mill diameter, a 1-1\/4-inch length of cut, and a 4-inch overall length with a straight 5\/16-inch shank. The 2-flute configuration and 45-degree helix angle promote chip evacuation and reduce built-up edge in soft, gummy metals. Micrograin carbide construction delivers hardness and edge retention at the cutting zone. The bright\/uncoated finish is standard for non-ferrous work where coating adhesion or heat is not a concern. Single-end geometry with right-hand cut and right-hand flute spiral. This tool is installed and operated by machinists and CNC tooling technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 17002963 is suited for profiling, slotting, and peripheral milling in aluminum, brass, copper, and other non-ferrous alloys. The long-length classification and 1-1\/4-inch length of cut allow access to deeper pockets and features without sacrificing rigidity for the given diameter. Centercutting capability enables direct plunge entry. The Series A245 designation places this tool within a defined geometry family intended for non-ferrous and light alloy applications. It is sold as a single-end tool, meaning the shank end is not a cutting end.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-inch diameter with mill diameter tolerance of +0.0000 to -0.0020 inches for consistent fit in toolholders\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes aggressive chip evacuation in aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for edge hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish — no coating buildup or thermal mismatch issues on non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute with no chipbreaker for clean, continuous chip formation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in aluminum and non-ferrous workpiece materials (material code N).

Secure the straight shank in a collet chuck or end mill holder to the appropriate clamping torque per the toolholder manufacturer's specifications. Verify runout does not exceed the 0.0005-inch maximum TIR before cutting. Confirm spindle direction is set to right-hand rotation before engaging the workpiece. Do not exceed the tool's rated depth of cut for the diameter class.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A245\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600 to -0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 17002963\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561569288498,"sku":"17002963","price":119.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff13367177960266139f121457a41b37_cca1d764-976d-4f8a-97bb-1245d83bada6.jpg?v=1786465755","url":"https:\/\/voomisupply.com\/products\/seco-17002963-square-end-mill-5-16-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
