Built from M2 high speed steel with a bright\/uncoated finish, it offers a 1 inch cutting diameter and a 1-7\/8 inch length of cut. The double-end design provides two usable cutting ends, extending tool life between changeouts. With four spiral flutes and a 30-degree helix angle, this end mill supports efficient chip evacuation and smooth cutting performance. It is center-cutting capable, allowing plunge entry into workpieces. Right-hand cutting and right-hand flute direction are standard on this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in vertical milling machines and CNC machining centers where fractional-inch tooling is standard. It handles profiling, slotting, and peripheral milling in ferrous and non-ferrous materials. The M2 HSS construction makes it a practical choice for shops that require a reliable general-purpose tool without the cost of carbide. Machinists and tool-and-die professionals are the primary installers and operators of this tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design delivers two cutting ends per tool, reducing per-cut tooling cost\u003c\/li\u003e\n\u003cli\u003eM2 high speed steel construction provides good toughness and wear resistance in general machining\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows direct plunge cuts without pre-drilling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes support efficient material removal in profiling and slotting applications\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish is compatible with a wide range of cutting fluids and workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for vertical mills and CNC machining centers accepting a 1 inch shank diameter with fractional-inch collets or end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Use a properly sized collet or end mill holder rated for 1 inch shank diameter to prevent runout. Inspect both cutting ends for damage before use and never exceed the machine manufacturer's recommended spindle speed or feed rate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M2\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 720-4120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692006408498,"sku":"720-4120","price":158.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d90da549a74cf86753431823b20bc3d.jpg?v=1788291944","url":"https:\/\/voomisupply.com\/products\/value-collection-720-4120-square-end-mill-1in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
