It carries a 3\/8-inch diameter with a 0.06-inch corner radius, producing a consistent blend between the floor and wall of a milled pocket or profile. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces at the tool tip. With four flutes and a right-hand cutting direction, this end mill is suited for finishing and semi-finishing passes in ferrous and non-ferrous materials. It is centercutting, allowing direct plunge entry. Machinists and CNC operators install and run this tool in vertical machining centers and manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for shop environments requiring tight-tolerance corner radii on machined components. The micrograin carbide substrate supports use in harder workpiece materials where high-speed steel tooling loses edge life prematurely. The bright, uncoated finish makes it a straightforward choice when coolant-based lubrication is used and coating interaction with the workpiece material is a concern. It is a single-end tool, meaning the cutting geometry is on one end only. Typical applications include pocket milling, contouring, and profile work on parts requiring a precise blend radius.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-inch mill diameter with a 0.06-inch corner radius for consistent blend geometry\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide construction for extended edge life in harder materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle for efficient chip evacuation and reduced cutting force\u003c\/li\u003e\n  \u003cli\u003eFour flutes with right-hand spiral and right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with coolant-based machining setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shank end mill compatible with 3\/8-inch collets, end mill holders, and milling chucks used in CNC vertical machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and locked out before loading or changing the tool. Seat the 3\/8-inch shank fully in the holder and torque the collet nut or set screws according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut, as excessive runout will accelerate corner radius wear and degrade surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.00150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 7\/8 inches (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.000000 to minus 0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: minus 0.0001 to minus 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 12182536\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728792125746,"sku":"12182536","price":44.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb734c0cefcb0c5204f7ea41f6c0aed1.jpg?v=1788696247","url":"https:\/\/voomisupply.com\/products\/accupro-12182536-corner-radius-end-mill-3-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
