With a 0.5 inch mill diameter, a 1 inch length of cut, and a 3 inch overall length, this single-end tool delivers aggressive material removal with tight dimensional control. The 0.120 inch corner radius reduces stress concentrations at the bottom of pockets and slots, extending tool life in high-load applications. AlCrTiN coating provides thermal resistance and hardness at elevated cutting temperatures. Five flutes with a 38-degree right-hand helix and variable index geometry reduce chatter and improve chip evacuation. The centercutting design allows plunge entry, adding flexibility in multi-axis and ramping operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for die and mold work, aerospace component machining, and general precision part production. The micrograin solid carbide substrate supports high-speed cutting in hardened steels, stainless, and cast iron. It is installed by machinists and CNC programmers running vertical or horizontal machining centers as well as manual mills requiring a robust corner-radius profile.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.120 inch corner radius reduces stress riser at pocket floors and improves surface finish\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating for high-temperature wear resistance in ferrous and hard-alloy cutting\u003c\/li\u003e\n\u003cli\u003e5-flute geometry increases feed rates compared to standard 4-flute designs\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic chatter during interrupted cuts\u003c\/li\u003e\n\u003cli\u003e38-degree right-hand helix promotes smooth chip evacuation and axial force balance\u003c\/li\u003e\n\u003cli\u003eCentercutting construction allows direct plunge entry without a pre-drilled pilot\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill for use in standard 1\/2 inch collet chucks, end mill holders, or hydraulic chucks on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the machine powered off and locked out per facility LOTO procedures. Ensure the shank seating depth meets holder manufacturer minimums to prevent pullout under load. Verify runout at the spindle prior to cutting. Do not exceed the coating or substrate temperature rating by running dry at feeds and speeds beyond the manufacturer recommendation for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.120 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 311630\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748862886194,"sku":"311630","price":131.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8254d0ae7b10182ca163db3aac307e6_493d8e75-5f9c-4608-94f3-f425dfadc9e1.jpg?v=1788899769","url":"https:\/\/voomisupply.com\/products\/accupro-311630-corner-radius-end-mill-1-2-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
