Built from M2 high speed steel with a bright uncoated finish, this tool delivers reliable performance in conventional milling setups. The 1\/4 inch cutting diameter pairs with a 3\/8 inch shank, providing a stable connection in standard collet or end mill holders. With a 1-3\/4 inch length of cut and a 3-1\/2 inch overall length, this is an extra-long configuration suited for applications requiring extended reach into workpieces or fixtures.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for use in vertical machining centers, knee mills, and manual milling machines across job shop, maintenance, and light production environments. The 30-degree helix angle and four-flute spiral geometry support smooth chip evacuation and surface finish on steel, aluminum, and similar materials. It is installed and operated by machinists and tool-and-die professionals working with fractional inch tooling systems. No coolant-through capability is present, so external coolant or flood cooling applies when required by the material or cut depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM2 high speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eFour-flute spiral geometry with 30-degree helix angle for improved chip flow and finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry directly into the workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute orientation — standard configuration for most milling setups\u003c\/li\u003e\n  \u003cli\u003eExtra-long length type with 1-3\/4 inch length of cut for extended reach applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup concerns when regrinding or inspecting edge condition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tool for milling machines accepting a 3\/8 inch shank end mill in standard collet chucks or end mill holders using fractional inch tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist. Secure the 3\/8 inch shank fully into a compatible collet or end mill holder, ensuring the shank is clean and free of burrs before tightening. Verify spindle runout is within acceptable limits before beginning a cut, as excessive runout accelerates edge wear on HSS tooling. Always bring the spindle to a full stop before changing or inspecting the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eLength of Cut\u003c\/strong\u003e: 1.75 inches (1-3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches (3-1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VCCC-HSS-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 720-3401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693104955698,"sku":"720-3401","price":35.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b0754c5b155ecbbd584f9983be9d3950.jpg?v=1788307389","url":"https:\/\/voomisupply.com\/products\/value-collection-720-3401-square-end-mill-1-4-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
