With a 1\/8 inch mill diameter and a 3\/8 inch length of cut, it handles slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The bright\/uncoated finish suits applications where coating is unnecessary or where regrinding is anticipated. At 3-1\/16 inches overall length with a 3\/8 inch shank diameter, this regular-length tool fits standard collet chucks and end mill holders common in manual mills and CNC machining centers. Licensed machinists and toolroom technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited to light-duty milling tasks in job shops, maintenance environments, and toolroom settings. The double-end configuration provides two usable cutting ends, extending tool life between replacements. The 30-degree right-hand helix and right-hand cutting direction produce efficient chip evacuation during climb or conventional milling in aluminum, mild steel, brass, and similar materials. It is not center-cutting, so it should not be used for direct plunge cuts without a pre-drilled pilot hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003eFour flutes with 30-degree right-hand spiral helix for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eM2 high speed steel construction for general-purpose machinability across common metals\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish allows easy regrinding and inspection\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eNot center-cutting — requires pilot hole for plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard toolroom end mill for use with 3\/8 inch collet chucks or end mill holders on manual knee mills and CNC machining centers accepting fractional-inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians familiar with collet and end mill holder systems. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Seat the shank fully into the holder to the recommended engagement depth and torque the set screw or collet nut per the holder manufacturer specification. Confirm runout with a dial indicator before beginning a cut to avoid premature tool wear or poor surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/16 inches (3.0625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel (M2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VCDE-HSS-4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 720-4004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692199543090,"sku":"720-4004","price":41.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89464b723d627125931eb0f15f940eb8.jpg?v=1788294494","url":"https:\/\/voomisupply.com\/products\/value-collection-720-4004-square-end-mill-1-8in-hss-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
