It features a 3\/8 inch diameter with a 0.06 inch corner radius, a 4-inch overall length, and a 1-3\/4 inch length of cut. The TiCN coating provides increased surface hardness and lubricity compared to uncoated carbide, extending tool life in ferrous and non-ferrous materials alike. With a 40-degree helix angle and right-hand spiral flute geometry, it promotes efficient chip evacuation. This is a single-end, centercutting tool, meaning it can plunge directly into a workpiece. Machinists and tool-and-die professionals are the primary installers and operators.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual mills where corner radius profiles are required on slots, pockets, and contoured surfaces. The extra-long length classification and 1-3\/4 inch length of cut make it practical for deeper cavity work in mold making, die work, and precision part production. The micrograin carbide substrate supports tight tolerances and stable performance at higher feed rates. It is appropriate for both roughing and finishing passes depending on depth of cut and feed parameters selected for the specific workpiece material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.06 inch corner radius reduces stress concentrations and improves edge durability on profiled cuts\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces friction for extended tool life\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate supports tight tolerances and high rigidity\u003c\/li\u003e\n  \u003cli\u003eExtra-long length classification provides reach for deeper cavity and pocket milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill compatible with standard 3\/8 inch collets and end mill holders used in CNC machining centers and conventional milling machines.\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. Secure the shank fully in a properly sized collet or end mill holder and verify runout before cutting. Ensure the spindle and workholding are powered down and the machine is in a safe state before loading or changing tooling. Do not exceed the tool's rated depth of cut per pass for the workpiece material being machined.\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/4 inches (0.2362 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\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\u003c\/strong\u003e: TiCN\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\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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 to -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 12183292\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733363818802,"sku":"12183292","price":162.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e82850b27706e34a9a8368f398cf8ba3.jpg?v=1788754709","url":"https:\/\/voomisupply.com\/products\/accupro-12183292-corner-radius-end-mill-3-8-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
