Built to Series A245 specifications, this single-end tool features a 0.25 inch mill diameter, a 0.375 inch length of cut, and a 2.5 inch overall length. The 45-degree helix angle promotes efficient chip evacuation in softer metals and composites, while the micrograin carbide substrate delivers edge retention through extended production runs. Two right-hand spiral flutes and a bright uncoated finish make this tool a direct choice for finishing and light roughing passes where coating adhesion or chemical reactivity is a concern. It is centercutting, allowing plunge entry without a pre-drilled hole.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers, knee mills, and manual milling machines running aluminum alloys, copper, brass, and other non-ferrous workpiece materials. The 0.25 inch straight shank fits standard ER collet chucks and end mill holders common in both production shops and job shops. The short length type keeps deflection low, making it appropriate for slot milling, profiling, and shoulder work in thin-wall aluminum parts and structural extrusions. Right-hand cut and right-hand flute geometry are standard for conventional and climb milling in these materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.25 inch mill diameter with +0.0000 to -0.0020 inch diameter tolerance for consistent sizing\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle optimized for chip flow in aluminum and non-ferrous alloys\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish eliminates coating buildup risk on sticky non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute spiral geometry for standard milling operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in aluminum and non-ferrous workpiece materials (Material Code N).

Secure the 0.25 inch straight shank in a clean, properly sized collet or end mill holder and torque to the holder manufacturer specification. Verify runout against the 0.0005 inch maximum TIR spec using a dial indicator before cutting. De-energize and lock out the machine spindle before changing or inspecting the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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\u003eSeries\u003c\/strong\u003e: A245\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 17002956\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559454507314,"sku":"17002956","price":60.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff13367177960266139f121457a41b37_7d6e410f-1d7b-4ea8-a79b-cb01dc0f3daa.jpg?v=1786432897","url":"https:\/\/voomisupply.com\/products\/seco-17002956-square-end-mill-0-25-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
