Built from solid carbide with an AlTiN coating, it delivers heat resistance and tool life in demanding cutting applications. The 4-flute geometry combined with a 270-degree wrap angle provides full radial engagement through undercut passes. The mill measures 0.125 inches in diameter with a 0.107-inch length of cut, a 0.076-inch neck diameter, and a 0.375-inch neck length. Right-hand flute direction and right-hand cutting direction make it compatible with standard spindle setups. It is installed by CNC machinists and tool-and-die professionals working in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis undercut end mill is suited for machining internal reliefs, snap-fit grooves, T-slots, and undercut profiles in molds, dies, and precision components. The reduced neck diameter allows access to recessed features without interference. The 1\/8-inch shank diameter fits standard collet systems on vertical machining centers and CNC mills. With a 1.5-inch overall length, it is sized for compact, close-tolerance work in both prototype and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e270-degree wrap angle enables full undercut engagement in a single pass\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life in harder materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and dimensional accuracy at small diameters\u003c\/li\u003e\n  \u003cli\u003e4-flute design balances chip evacuation with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eReduced neck diameter of 0.076 inches allows reach into recessed or deep-pocket features\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for compatibility with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard catalog undercut end mill for use in 1\/8-inch collet or end mill holders on CNC vertical machining centers and milling machines requiring a single-end undercut geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified CNC machinist or toolroom professional. Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before inserting or removing the tool. Seat the 0.125-inch shank fully into the collet to the recommended grip length to minimize runout. Do not exceed manufacturer-recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.107 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.076 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.375 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\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\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eWeight\u003c\/strong\u003e: 0.01 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: 39708-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51739965489458,"sku":"39708-C3","price":82.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29dc6da053002fa747a0ecadbfc0443f_58327b38-fbaa-4017-9684-a5f21c9df28a.jpg?v=1788820824","url":"https:\/\/voomisupply.com\/products\/harvey-tool-39708-c3-undercut-end-mill-1-8-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
