Designed for undercutting, back-milling, and locking-groove operations, this tool features a 270-degree wrap angle that enables aggressive material removal in applications where standard end mills cannot reach. The 0.125-inch mill diameter pairs with a 0.107-inch length of cut and a 0.076-inch neck diameter, giving the tool the clearance geometry needed to machine undercut profiles in confined pockets. Right-hand flute direction and right-hand cutting direction are standard. At 0.01 pounds, the tool is suited for precision machining centers running tight tolerances.\u003c\/p\u003e\n\u003cp\u003eThis undercut end mill is intended for use in CNC machining centers where undercut slots, locking grooves, and T-slot-style profiles are required. The 0.125-inch shank diameter fits standard 1\/8-inch collets commonly found on high-speed spindles. The 0.750-inch neck length provides reach into deep pockets while keeping the neck diameter small enough to clear surrounding walls. The 1\/16-inch corner radius helps reduce stress concentrations at the base of undercut features. Typical applications include mold and die work, medical component machining, and aerospace part production where undercut geometry is a design requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e270-degree wrap angle enables true undercut and back-milling profiles\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration balances chip evacuation with surface finish quality\u003c\/li\u003e\n  \u003cli\u003e0.076-inch neck diameter provides clearance for deep pocket and confined-space operations\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for non-ferrous metals, plastics, and general-purpose machining\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification solid carbide undercut end mill for use in CNC machining centers equipped with 1\/8-inch collet toolholders.\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 the machine is in a safe state before loading or changing tooling. Seat the 0.125-inch shank fully into the collet and torque the collet nut to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning the cut, as even small amounts of runout significantly affect tool life and feature accuracy at this diameter.\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: 2 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: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\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 Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 41308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51735249027378,"sku":"41308","price":82.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf3eecd4f71ed7d82f9a8581e84c6290_901a8cf4-c2c3-486f-b730-21a5bf60421a.jpg?v=1788770924","url":"https:\/\/voomisupply.com\/products\/harvey-tool-41308-undercut-end-mill-1-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
