Built from micrograin carbide stock, it carries an AlTiN (aluminum titanium nitride) coating that increases surface hardness and heat resistance during high-speed cuts. The tool features a 30-degree right-hand spiral flute geometry and is centercutting, allowing direct plunge entry without a pre-drilled pilot hole. With a 1\/8 inch cutting diameter and 1 inch length of cut, it is well-suited for slotting, profiling, and pocket milling in tight workspaces or on small-format CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits residential shop, production, and tool-and-die applications where a long-series, small-diameter carbide tool is required. The 3 inch overall length provides extended reach for deeper setups while the 1\/8 inch straight shank seats directly into standard collet chucks and ER collet systems. Right-hand cut and right-hand flute configuration follows conventional milling standards. The long length-of-cut classification makes it a practical choice for mold work, engraving, and detailed contouring operations on CNC mills or manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and tool life at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry with 30-degree helix angle for smooth chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n  \u003cli\u003eLong-series overall length of 3 inches supports extended-reach setups\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — compatible with conventional CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for CNC machining centers and manual mills using 1\/8 inch collet chucks or ER collet systems requiring a long-series 4-flute square end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet to the recommended engagement depth and torque the collet nut to the collet manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates wear on small-diameter carbide tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill 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\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 of Cut\u003c\/strong\u003e: 1 inch (1.0000 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\u003eOverall Length\u003c\/strong\u003e: 3 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\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\u003eLength Type\u003c\/strong\u003e: Long Series\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (H x W x L)\u003c\/strong\u003e: 0.3 x 0.3 x 3 inches\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: 750375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732874658098,"sku":"750375","price":47.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ff3f661db45c2c700fd7200fd36f6d3.jpg?v=1788747797","url":"https:\/\/voomisupply.com\/products\/hertel-750375-square-end-mill-1-8-inch-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
