It features a 5\/8 inch (0.625 inch) cutting diameter with four flutes and a 1-3\/8 inch length of cut, providing ample chip evacuation and a clean shoulder profile. The tool is manufactured from high speed steel (HSS) and finished with a Titanium Nitride (TiN) coating, which increases surface hardness and extends tool life compared to uncoated HSS. Machinists and tool-and-die professionals use this end mill for slotting, profiling, and contouring cuts on ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in vertical machining centers, knee mills, and manual milling machines where a 1\/2 inch straight shank is compatible with the collet or end mill holder. With a 30-degree helix angle and right-hand cutting and flute direction, it produces smooth cuts in a conventional milling setup. It is appropriate for job shop production, maintenance machining, and general fabrication where an economical HSS tool with coating is preferred over solid carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8 inch cutting diameter with 1-3\/8 inch length of cut for versatile depth capability\u003c\/li\u003e\n  \u003cli\u003eFour spiral flutes with right-hand cut and right-hand flute direction\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes efficient chip flow and reduces chatter\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends tool life and reduces friction on cutting edges\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch shank diameter fits standard collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-end square end mill with a 1\/2 inch shank, compatible with milling machines and machining centers equipped with matching collet or end mill holder systems.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Seat the shank to the recommended insertion depth in the collet or holder to avoid runout and tool pull-out during cutting. Follow applicable workplace safety standards and machine manufacturer guidelines for feed rate and speed selection when using HSS tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\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: 1-3\/8 inches (1.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches (3.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.500 inches)\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\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: -20550-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51705327943986,"sku":"-20550-10","price":67.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9cc9f6faaaf346755d76f6392a3accc.jpg?v=1788428279","url":"https:\/\/voomisupply.com\/products\/value-collection-20550-10-square-end-mill-5-8-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
