Built from M2 high speed steel with a bright\/uncoated finish, it delivers consistent performance in a wide range of ferrous and non-ferrous materials. The 1\/4 inch diameter cutting end pairs with a 5\/8 inch length of cut, giving machinists a compact, rigid geometry suited for slotting, profiling, and peripheral milling. With a 30-degree helix angle and right-hand cutting and flute direction, this end mill produces clean chip evacuation and smooth surface finishes in conventional milling setups.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in manual knee mills, CNC machining centers, and drill press setups where a 3\/8 inch shank is accommodated. The double-end configuration extends tool life by providing two usable cutting ends, making it a practical choice for production shops and tool crib restocking. It is appropriate for light-to-medium-duty milling passes in tool steels, aluminum, brass, and similar materials. The regular-length design and fractional inch sizing make it compatible with standard collets and end mill holders used in everyday shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design provides two usable cutting ends, extending tool service life\u003c\/li\u003e\n  \u003cli\u003eM2 high speed steel construction offers good toughness and wear resistance for general milling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes efficient chip evacuation and smooth cut finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute direction for use in standard spindle setups\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids on a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eFour-flute geometry increases feed rate capability compared to two-flute designs in harder materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard fractional-inch replacement or stock end mill for use in any machine tool equipped with a 3\/8 inch collet or end mill holder accepting a 3\/8 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the collet or holder and torque the drawbar or collet nut per the machine manufacturer specification. Inspect the cutting edges for chips or damage before each use, and confirm proper tool runout with a dial indicator when precision work is required.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches (3.3750 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 grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\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: 0.08 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: 720-4020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691025858866,"sku":"720-4020","price":39.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6a4beee9f11194256d7d77423fd774e.jpg?v=1788279485","url":"https:\/\/voomisupply.com\/products\/value-collection-720-4020-square-end-mill-1-4-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
