Built from M2 high speed steel with a bright uncoated finish, it delivers reliable cutting performance without the added cost of specialty coatings. The tool measures 0.8661 inches (22 mm) in diameter, features a 1-7\/8 inch length of cut, and runs a 30-degree helix angle across four spiral flutes. Its centercutting geometry allows it to plunge directly into workpiece material. Machinists and toolroom professionals working on manual or CNC mills are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling in job shop, toolroom, and maintenance environments. The 7\/8 inch shank diameter and 4-1\/8 inch overall length make it a practical fit for standard milling machine and machining center collet and holder setups. Right-hand cut and right-hand flute orientation follow the most common spindle configuration. The M2 steel grade provides good toughness and wear resistance for interrupted cuts and general ferrous and non-ferrous stock removal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM2 high speed steel construction for toughness in general milling applications\u003c\/li\u003e\n  \u003cli\u003eFour spiral flutes with 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into material\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suited for use with cutting fluids across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSingle-end tool with right-hand cut and right-hand flute orientation\u003c\/li\u003e\n  \u003cli\u003eNo chipbreaker, no variable helix, no coolant-through — straightforward general-purpose geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard toolroom end mill compatible with 7\/8 inch collets, end mill holders, and milling arbors used on conventional and CNC vertical milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with tool holding systems and machine operation. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet or set screw is torqued to the holder manufacturer specification before running. Inspect the cutting edges for chips or damage before each use, and confirm spindle speed and feed rate are appropriate for the workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.8661 inches (22 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inches (1.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/8 inches (4.1250 inches)\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.1033 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: 720-8220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714293629234,"sku":"720-8220","price":97.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/072ce9ba0e85ee36eeb43bb6beec4383.jpg?v=1788498955","url":"https:\/\/voomisupply.com\/products\/value-collection-720-8220-square-end-mill-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
