The cutting diameter measures 0.375 inches with a 1 inch length of cut (LOC), and the shank diameter matches at 0.375 inches for direct fit into standard collets and tool holders. Overall length is 2.75 inches. The TiAlN (Titanium Aluminum Nitride) coating provides elevated heat resistance, extending tool life in dry or semi-dry machining conditions. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This end mill is centercutting, allowing plunge entry directly into the workpiece. Machinists and toolroom operators in job shops, production environments, and maintenance departments are the typical users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, peripheral milling, and plunge operations in ferrous and non-ferrous materials. The ultra micrograin carbide substrate supports high surface speeds while maintaining edge integrity in demanding cuts. Right-hand cut and right-hand flute geometry is standard, compatible with conventional CNC machining centers and manual knee mills. The spiral flute design and TiAlN finish make it particularly effective in hardened steels, stainless steels, and cast iron at elevated cutting parameters. Single-end configuration means the tool is replaced rather than indexed when the cutting edge is worn.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide ultra micrograin substrate for extended tool life and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for high-temperature resistance in ferrous and hardened material machining\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes efficient chip evacuation and reduces cutting force\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute — standard orientation for CNC and manual mills\u003c\/li\u003e\n  \u003cli\u003eMatched shank and cutting diameter at 0.375 inches simplifies toolholder selection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill for standard 3\/8 inch collets, end mill holders, and shrink-fit toolholders used in 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 or toolroom technician with the spindle fully stopped and the machine in a locked-out, de-energized state before tool changes. Ensure the collet or toolholder is clean and free of chips before seating the shank to the full recommended engagement depth. Do not exceed the rated LOC during cutting passes, as overhanging the fluted section beyond the stated 1 inch can induce deflection and premature breakage. Follow the machine tool manufacturer and tooling manufacturer recommendations for speeds and feeds appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1 inch\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\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.75 inches\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\u003eCoating \/ Finish\u003c\/strong\u003e: TiAlN\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\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\u003eWeight\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: EM15402401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747726754098,"sku":"EM15402401","price":103.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57c9ae0c416fce2e90822e074181054d.jpg?v=1788884722","url":"https:\/\/voomisupply.com\/products\/accupro-em15402401-square-end-mill-3-8-inch-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
