It features a 3\/16 inch diameter with a matching 3\/16 inch shank, a 3\/8 inch length of cut, and a 0.01 inch corner radius that reduces stress concentration at the bottom of a slot or pocket while improving surface finish. The micrograin solid carbide construction provides hardness and wear resistance suited to ferrous and non-ferrous materials. A 40-degree helix and four right-hand spiral flutes promote efficient chip evacuation. This is a single-end, centercutting tool, meaning it can plunge directly into material. It is installed and operated by machinists, tool-and-die workers, and CNC programmers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for stub-length milling applications where rigidity and minimal deflection are priorities. Its compact 2 inch overall length and stub classification make it appropriate for tight-clearance setups on vertical machining centers, CNC mills, and manual knee mills. The bright uncoated finish makes it a practical choice for general-purpose milling of aluminum, brass, plastics, and softer steels where a coating is not required. The corner radius geometry is particularly useful when milling pockets or profiles that require a small, controlled radius at internal corners.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for wear resistance and cutting edge integrity\u003c\/li\u003e\n\u003cli\u003e0.01 inch corner radius reduces stress concentration and improves pocket floor finish\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes with 40-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eStub-length classification at 2 inches OAL maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose non-ferrous and softer ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for 3\/16 inch collet or end mill holder setups on vertical machining centers, CNC mills, and manual milling machines accepting right-hand cutting tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a compatible 3\/16 inch collet, end mill holder, or shrink-fit holder. Ensure the spindle is fully powered down and locked before tool changes. Verify runout with a dial indicator after installation, as shank diameter tolerance is -0.0001 to -0.0004 inches and excessive runout will accelerate wear. Follow the machine manufacturer and tooling supplier feed and speed recommendations for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002500 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eLength Type\u003c\/strong\u003e: Stub\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: 0.03 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: 12182755\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728876142898,"sku":"12182755","price":32.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d3d8d6b6f63443d056de4c02b161d96.jpg?v=1788697253","url":"https:\/\/voomisupply.com\/products\/accupro-12182755-corner-radius-end-mill-3-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
