With a 0.0313-inch cutting diameter and a 0.005-inch corner radius, this tool reduces stress concentrations at the cutting edge and improves surface finish in slotting, profiling, and pocket-milling applications. The 4-flute, right-hand spiral geometry delivers efficient chip evacuation and stable cutting action. Micrograin carbide construction provides the hardness and wear resistance needed for demanding cuts in ferrous and non-ferrous materials. This end mill is intended for use by machinists and tooling professionals working on CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for fine detail work in mold making, die work, and precision part machining where sharp inside corners must be avoided or radius blending is required. The single-end, centercutting design allows plunge entry in addition to standard peripheral and slot cutting. The bright, uncoated finish makes it a practical choice for aluminum, brass, and other non-ferrous materials where coating adhesion is not required and tool identification after use is straightforward.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0313-inch cutting diameter with a 0.005-inch corner radius for controlled edge blending\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand spiral geometry for efficient chip removal and surface finish\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide construction for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling in addition to peripheral cuts\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for non-ferrous and general-purpose milling\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 0.375-inch length of cut and 1.5-inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for CNC machining centers and manual milling machines accepting a 0.125-inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully de-energized and at a complete stop before changing tooling. The 0.125-inch shank should be secured in a compatible collet or end mill holder to the manufacturer-specified clamping depth. Verify runout with a dial indicator after installation and before beginning any cut to protect both the tool and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.0313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0002 \/ -0.0008 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: 0.375 inches (3\/32 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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 Type\u003c\/strong\u003e: Corner Radius\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.13 x 0.25 x 0.25 inches\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: 12176874\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730015420722,"sku":"12176874","price":28.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5dc09ca753e9261f51a7215871b7101.jpg?v=1788710219","url":"https:\/\/voomisupply.com\/products\/accupro-12176874-corner-radius-end-mill-0-0313in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
