It features a 0.25-inch cutting diameter, a 0.75-inch length of cut, and a 2.5-inch overall length with a 0.25-inch straight shank. The two-flute geometry and 45-degree helix angle promote efficient chip evacuation in softer, gummy materials where flute loading is a common problem. Micrograin carbide substrate provides the edge retention and rigidity needed for consistent dimensional accuracy. This is a single-end, centercutting tool, meaning it can be plunged directly into the workpiece without a pre-drilled entry point. It ships uncoated, which is the standard choice for aluminum to prevent built-up edge.\u003c\/p\u003e\u003cp\u003eThis end mill is built for light to medium milling operations on aluminum, copper, brass, and other non-ferrous materials. Typical applications include slotting, profiling, and pocketing on CNC machining centers and manual mills. The right-hand cut and right-hand spiral flute configuration suits standard spindle rotation on most vertical and horizontal milling setups. The Series A245 designation places it within SECO's catalog of general-purpose fractional-inch solid carbide end mills aimed at production and job shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate for edge retention in non-ferrous applications\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes chip evacuation in aluminum and soft metals\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish minimizes material adhesion when machining aluminum\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute for standard CNC and manual mill compatibility\u003c\/li\u003e\n\u003cli\u003eStraight shank fits standard 1\/4-inch collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide end mill for use in standard 1\/4-inch collet systems and end mill holders on CNC machining centers and manual vertical mills.

Power down and lock out the spindle before inserting or removing the tool from the holder. Secure the shank in a clean, undamaged 1\/4-inch collet or end mill holder and verify runout does not exceed the maximum TIR of 0.0005 inches before cutting. Do not use this tool on ferrous materials, as the uncoated carbide substrate and flute geometry are not optimized for steel or cast iron.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.75 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eWeight\u003c\/strong\u003e: 0.2 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: 17002957\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563945558322,"sku":"17002957","price":67.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff13367177960266139f121457a41b37_945ef1d2-9d84-4663-9868-58ceb3cf1313.jpg?v=1786507490","url":"https:\/\/voomisupply.com\/products\/seco-17002957-square-end-mill-0-25-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
