With a 5\/8 inch diameter and a 1-1\/4 inch length of cut, this single-end tool delivers consistent material removal in ferrous and non-ferrous applications. The 4-flute, right-hand cutting geometry with a 30-degree helix angle provides good chip evacuation and surface finish quality. The micrograin carbide construction gives the tool the rigidity and edge retention needed for demanding production runs. Machinists and tool-and-die professionals working on CNC mills and manual knee mills are the primary users of this type of cutter.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling operations in shop and production environments. The bright\/uncoated finish makes it a versatile choice for general-purpose cutting where coating is not required or where the base carbide substrate is preferred for specific materials. The 5\/8 inch shank diameter matches the cutter diameter, providing direct collet or end mill holder engagement without reduction sleeves. The 3-1\/2 inch overall length fits standard toolholding setups on most vertical machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-flute, right-hand cutting and right-hand flute direction for standard CNC and manual mill spindles\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for balanced chip load and surface finish\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for general-purpose and non-coated applications\u003c\/li\u003e\n\u003cli\u003e5\/8 inch shank diameter with tight tolerance of +0.0000 to -0.0003 inches for secure toolholder fit\u003c\/li\u003e\n\u003cli\u003eNon-centercutting geometry  -  not designed for direct plunge operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose solid carbide square end mill compatible with standard collet chucks, end mill holders, and shrink-fit toolholders accepting a 5\/8 inch shank on CNC vertical machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder rated for the 5\/8 inch shank diameter and torque the retention mechanism per the toolholder manufacturer specifications. Confirm cutting direction is set to right-hand before initiating a cut, and do not use this tool for plunge cutting as it is non-centercutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches (3.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.625 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: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to -0.0012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.49 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: YG-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GM153040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YG-1","offers":[{"title":"Default Title","offer_id":67912311537970,"sku":"GM153040","price":229.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44964418f1bcfb8f3780bceadd8f39ad.jpg?v=1791232816","url":"https:\/\/voomisupply.com\/products\/yg-1-gm153040-square-end-mill-5-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
