It features a 3\/8 inch diameter with a 5\/8 inch length of cut and a 0.045 inch corner radius that reduces stress concentrations at the base of a cut, extending tool and workpiece life. The body is manufactured from micrograin solid carbide and finished with a TiCN coating for improved wear resistance and performance in ferrous and non-ferrous materials. A 40-degree helix angle promotes efficient chip evacuation. This tool is installed and operated by machinists and CNC programmers running vertical or horizontal milling machines.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for stub-length milling operations requiring tight tolerances and a radiused corner profile. Its centercutting geometry allows plunge entry as well as conventional peripheral and slot milling. The right-hand flute direction and right-hand cutting orientation make it compatible with standard spindle configurations. Typical applications include profiling, contouring, pocketing, and finishing passes on steel, stainless, cast iron, and similar materials where the TiCN coating provides meaningful abrasion resistance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves wear resistance across a range of ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e0.045 inch corner radius reduces stress risers and extends workpiece and tool life\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes chip evacuation during deep or full-width cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003e4 flutes with right-hand spiral and right-hand cutting direction for standard CNC and manual mill spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use stub-length corner radius end mill for standard 3\/8 inch collets, end mill holders, and milling chucks used in CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and locked out before loading or removing the tool. Seat the 3\/8 inch shank fully into a clean, properly sized collet or end mill holder and torque to the tool holder manufacturer's specification. Inspect the corner radius and cutting edges for chips or wear before each use, and follow all applicable shop safety and machine guarding practices.\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\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 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\u003eCorner Radius\u003c\/strong\u003e: 0.045 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: +0.0000 to -0.0025 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\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 Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\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\u003eWeight\u003c\/strong\u003e: 0.12 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: 12182886\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744493306162,"sku":"12182886","price":63.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebb4e71ad34255df34cad1911e597bdc.jpg?v=1788857328","url":"https:\/\/voomisupply.com\/products\/accupro-12182886-corner-radius-end-mill-3-8-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
