With a 0.125-inch cutting diameter, a 0.625-inch length of cut, and a 2-inch overall length, this tool is built for tight-tolerance slotting, profiling, and plunging in confined workspaces. The ultra-micrograin carbide substrate provides edge strength and wear resistance, while the titanium aluminum nitride (TiAlN) coating extends tool life at elevated cutting temperatures. Four right-hand spiral flutes at a 30-degree helix angle promote efficient chip evacuation and smooth finishes. This end mill is centercutting, allowing direct plunge entry without a pre-drilled hole.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers, vertical mills, and manual knee mills used in job shops, tool rooms, and production environments. The 1\/8-inch shank diameter is compatible with standard collets and end mill holders used in both small-format machining centers and benchtop CNC routers. It is a common choice for detail work, narrow slot milling, and finish passes on ferrous and non-ferrous metals. Machinists handling precision components, prototype parts, or die and mold work will find the compact geometry well suited to fine-feature applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid ultra-micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for extended tool life at high cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e4 right-hand spiral flutes with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle direction\u003c\/li\u003e\n  \u003cli\u003eSingle-end tool with 0.625-inch length of cut and 2-inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/8-inch shank square end mill compatible with collet chucks, ER collet systems, and end mill holders sized for 1\/8-inch shanks on CNC machining centers and manual 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 runout tolerances. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank to the recommended gauge-line depth in the collet or holder and torque the retention hardware per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout at this diameter will significantly shorten tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.125 inches (1\/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\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Ultra Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.5 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EM15300801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754348511538,"sku":"EM15300801","price":50.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a007baa4187afc967bb311f9e6e83226.jpg?v=1788944536","url":"https:\/\/voomisupply.com\/products\/accupro-em15300801-square-end-mill-1-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
