It features a 3\/8 inch diameter, a 1-3\/4 inch length of cut, and a 0.0100 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life compared to sharp-corner designs. The 4-flute, right-hand spiral geometry and 40-degree helix angle promote efficient chip evacuation and smooth surface finishes. A TiCN (titanium carbonitride) coating adds hardness and lubricity, making this tool well suited for harder steels and high-cycle production environments. Micrograin carbide substrate provides the toughness and edge retention needed for demanding cut conditions.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers, vertical mills, and multi-axis setups in job shops, production facilities, and toolrooms. The extra-long 4 inch overall length and single-end, centercutting design allow it to reach into deeper pockets and perform both plunge and peripheral milling operations. Right-hand cutting direction is standard for conventional and climb milling strategies on most CNC platforms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention in hardened and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces built-up edge in ferrous applications\u003c\/li\u003e\n\u003cli\u003e0.0100 inch corner radius reduces stress risers and extends tool and workpiece life\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip flow and improved surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry without a pre-drilled start hole\u003c\/li\u003e\n\u003cli\u003eExtra-long 4 inch OAL provides reach for deep-pocket and extended-reach milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8 inch shank end mill compatible with ER collet chucks, end mill holders, and shrink-fit tooling systems that accept 3\/8 inch shanks on CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before inserting or removing tooling. Verify collet or holder runout with a dial indicator before production use, as excessive runout accelerates flute wear and reduces dimensional accuracy. Do not exceed the recommended depth-of-cut and feed-per-tooth parameters for the workpiece material and machine rigidity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\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 (1.7500 inches)\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\u003eCorner Radius\u003c\/strong\u003e: 0.0100 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\u003eLength Type\u003c\/strong\u003e: Extra Long\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 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\u003eWeight\u003c\/strong\u003e: 0.4 pounds\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: 12183286\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730577522994,"sku":"12183286","price":157.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec250f6f1ab481d6f77ee9a882216107.jpg?v=1788719808","url":"https:\/\/voomisupply.com\/products\/accupro-12183286-corner-radius-end-mill-3-8-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
