Built from M2 high speed steel with a bright uncoated finish, it features a 3\/8 inch cutting diameter, a 3\/4 inch length of cut, and a 30-degree spiral helix angle across four flutes. The right-hand cut and right-hand flute orientation suit conventional milling setups. Centercutting geometry allows the tool to plunge directly into the workpiece, adding versatility to slotting, profiling, and pocketing operations. Machinists and toolroom technicians are the primary users of this type of end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard milling machines, CNC machining centers, and knee mills using a 3\/8 inch collet or end mill holder. The regular-length body and 2-1\/2 inch overall length make it appropriate for general-depth cuts in steel, aluminum, brass, and other machinable materials where a coated carbide tool is not required. It is well suited to job shops and maintenance machining environments where HSS tooling is preferred for interrupted cuts or low-speed applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM2 high speed steel construction for toughness in interrupted cuts and low-to-moderate spindle speeds\u003c\/li\u003e\n  \u003cli\u003eFour-flute design balances material removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard milling spindle direction\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating delamination risk on regrind\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard fractional-inch end mill for use in any milling machine or machining center equipped with a 3\/8 inch collet, end mill holder, or ER-style chuck.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Power down and lock out the spindle before changing tooling. Secure the shank fully within the collet or holder to the manufacturer-specified engagement depth, and verify runout with a dial indicator before beginning a cut. Do not exceed the recommended depth of cut for the material and spindle speed being used.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 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\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\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\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: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VCCC-HSS-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: 720-3209\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690882400562,"sku":"720-3209","price":36.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b256970de6709ae8748b53fb92ff73b.jpg?v=1788276925","url":"https:\/\/voomisupply.com\/products\/value-collection-720-3209-square-end-mill-3-8-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
