Built with a 270-degree wrap angle and a 45-degree helix, this 4-flute tool generates a smooth, aggressive cut in a right-hand cutting and right-hand flute direction. The AlTiN coating provides elevated heat and wear resistance, making this cutter well-suited for hard and abrasive workpiece materials. At 0.5 inches in diameter with a 0.427-inch length of cut and a 1\/4-inch corner radius, it handles detail work where standard end mills cannot reach. Machinists and tool-and-die professionals specify this geometry for finishing passes in complex part profiles.\u003c\/p\u003e\n\u003cp\u003eThis undercut end mill is used in CNC machining centers for contour milling, relief cutting, and undercut profiling on ferrous and non-ferrous materials. The reduced neck diameter of 0.323 inches and a 1-inch neck length allow the tool to reach into recessed pockets and channels without interference from the shank. It is a single-end tool on a 0.5-inch shank, compatible with standard ER collet systems and end mill holders commonly found in vertical and horizontal machining centers. Applications include mold and die work, aerospace component finishing, and precision part production runs where tight tolerances on undercut geometry are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e270-degree wrap angle enables full undercut profiling in a single pass\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes chip evacuation and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating extends tool life in high-heat and abrasive cutting conditions\u003c\/li\u003e\n  \u003cli\u003eReduced neck diameter of 0.323 inches provides clearance in deep or narrow pockets\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability under load\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for use on standard CNC spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and direct-fit undercut end mill for use in standard 0.5-inch end mill holders and ER collet chucks on CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully into the collet or holder to the recommended minimum engagement depth before torquing the retention mechanism. Verify runout with a dial indicator before beginning a cutting operation, as excessive runout will accelerate wear on the AlTiN coating and reduce dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.427 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrap Angle\u003c\/strong\u003e: 270 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 994732-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51731587596594,"sku":"994732-C3","price":330.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5aa829f9aa319b1b3673efd21bbbb71.jpg?v=1788732876","url":"https:\/\/voomisupply.com\/products\/harvey-tool-994732-c3-undercut-end-mill-0-5in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
