With a 1\/4 inch mill diameter and a 0.0300 inch corner radius, it produces smooth, consistent edge transitions while reducing stress concentrations in the workpiece. The AlTiN coating provides high heat resistance and extended tool life at elevated cutting speeds. Four flutes with a 30-degree right-hand helix deliver efficient chip evacuation and a fine surface finish. At 2-1\/2 inches overall length with a 3\/4 inch length of cut, this tool suits tight-tolerance work where tool reach and rigidity are both critical. Micrograin carbide grade supports edge retention in hard and abrasive materials. Installed and operated by machinists and toolroom professionals in CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits into the miniature series, making it well-suited for small-feature milling, contouring, and profiling in die and mold work, aerospace components, and precision medical parts. The centercutting design allows direct plunge entry, adding versatility to slotting and pocket milling operations. The single-end configuration and 1\/4 inch shank diameter are standard for compact toolholders and collet chucks common in high-speed machining setups. Right-hand cutting direction is compatible with conventional CNC spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0300 inch corner radius reduces edge chipping and workpiece stress concentrations\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry supports higher feed rates and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction maintains edge sharpness in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix promotes efficient chip evacuation in deep pockets and slots\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cutting tool for 1\/4 inch collet chucks and toolholders in CNC machining centers, VMCs, and manual mills accepting standard 1\/4 inch shank end mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists familiar with CNC or manual milling equipment. Ensure the spindle is fully stopped and the machine is powered down before loading or unloading the tool from its holder. Use a properly sized collet or end mill holder and torque to toolholder manufacturer specifications to prevent pullout. Verify runout with a dial indicator after installation before beginning a cut, especially in tight-tolerance applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7500 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\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12467994\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51752923070770,"sku":"12467994","price":46.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/185dbfcde53e699df0a7ea79df504a5e.jpg?v=1788931157","url":"https:\/\/voomisupply.com\/products\/accupro-12467994-corner-radius-end-mill-1-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
