Manufactured from M2 high speed steel with a bright uncoated finish, this tool delivers a 0.25-inch cutting diameter and a 1.25-inch length of cut, making it well suited for applications requiring moderate depth in a compact form factor. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation and reduces heat buildup during cuts. With four flutes, this end mill provides a good balance of chip clearance and surface finish quality. It is center-cutting, allowing plunge entry directly into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in manual milling machines and CNC machining centers across job shops, maintenance facilities, and light manufacturing environments. The long-length designation and 0.375-inch shank diameter make it a practical choice for reaching into deeper features while maintaining rigidity. It is appropriate for milling keyways, slots, pockets, and profiles in mild steel, aluminum, brass, and similar materials. Machinists, toolmakers, and general maintenance technicians are the primary users of this type of tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM2 high speed steel construction for durability across general-purpose milling applications\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design with 30-degree helix angle for efficient chip evacuation and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable — allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard milling machine compatibility\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — ready to run as-is or accept aftermarket coating if desired\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with a 0.375-inch shank diameter for secure collet or end mill holder retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard fractional-inch shank end mill compatible with collets, end mill holders, and milling chucks sized for a 3\/8-inch shank diameter on conventional and CNC milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the milling machine spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in the collet or holder and confirm proper torque on all retention hardware before initiating any cut. Inspect the cutting edges for chips or damage before each use.\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\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches (1-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0625 inches (3-1\/16 inches)\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: 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: 0.09 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: 720-3301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691533074738,"sku":"720-3301","price":44.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96dae86aff69528c625884eb2646d307.jpg?v=1788286628","url":"https:\/\/voomisupply.com\/products\/value-collection-720-3301-square-end-mill-1-4-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
