Built from micrograin solid carbide and finished with an AlTiN (aluminum titanium nitride) coating, this tool delivers extended wear resistance and thermal stability at elevated cutting speeds. It carries a 1\/16 inch mill diameter, a 1\/8 inch length of cut, and a 30-degree right-hand helix with four flutes. The stub-length configuration provides rigidity in tight setups. This tool is installed and operated by machinists, tool-and-die makers, and CNC technicians working on mills and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slot milling, profiling, and contouring operations in ferrous alloys, hardened steels, stainless steels, and high-temperature alloys where the AlTiN coating provides a thermal barrier that extends tool life. The stub length and small diameter make it effective in confined cavities and fine-detail work common in mold, die, and precision component machining. It is a single-end tool, so the full length is available for setup reach within the 1-1\/2 inch overall length. Center-cutting capability allows plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides rigidity and edge retention at small diameters\u003c\/li\u003e\n  \u003cli\u003eFour-flute spiral design with 30-degree right-hand helix balances chip evacuation and finish quality\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge milling without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eStub length classification reduces deflection risk on small-diameter tools\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch shank diameter fits standard collets and end mill holders on most CNC and manual mills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cutting tool for machining centers and manual mills accepting a 1\/8 inch shank diameter collet or end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists and CNC operators using a compatible collet or end mill holder sized for a 1\/8 inch shank. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Confirm runout with a dial indicator after seating to avoid premature edge failure at this diameter. Follow machine manufacturer feed and speed recommendations for the work material and coating type; do not exceed the rated depth of cut for the 1\/8 inch length 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: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\u003ePackage Dimensions\u003c\/strong\u003e: 3 inches L x 0.3 inches W x 0.3 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750415\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736756322610,"sku":"750415","price":20.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a7a0583ca0ef5b30d37bf58f44449e4.jpg?v=1788779977","url":"https:\/\/voomisupply.com\/products\/hertel-750415-square-end-mill-1-16-in-4-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
