It features a 1\/8 inch cutting diameter with a 1\/4 inch length of cut and a 1-1\/2 inch overall length. The four-flute, spiral design with a 30-degree helix angle promotes efficient chip evacuation and surface finish quality. An AlTiN (aluminum titanium nitride) coating provides heat resistance and extended tool life in ferrous and hard material cuts. The micrograin carbide substrate adds toughness and edge retention. This stub-length end mill is installed and used by machinists and CNC operators in job shops, production facilities, and toolrooms.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling in ferrous metals, alloys, and hardened materials where heat generation is a concern. The centercutting geometry allows plunge entry, adding flexibility in programming and fixturing. The stub length designation provides added rigidity compared to standard or long-reach configurations, making it appropriate for applications where chatter control and dimensional accuracy are priorities. Right-hand cut and right-hand flute orientation are standard for conventional CNC milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for thermal protection and extended tool life in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eStub length (1\/4 inch LOC) provides increased rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard CNC milling machine spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 1\/8 inch collet or end mill holder systems on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using a compatible 1\/8 inch collet, shrink-fit holder, or end mill holder. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Confirm runout with a dial indicator after seating the tool, as runout on small-diameter carbide end mills accelerates breakage. Follow shop-specific feeds, speeds, and depth-of-cut parameters appropriate for the workpiece material and machine rigidity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inch (1.5000 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\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\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: Stub\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 750288\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733569962290,"sku":"750288","price":21.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/287ca6414f5c196188accd37aa4bb1ef.jpg?v=1788756439","url":"https:\/\/voomisupply.com\/products\/hertel-750288-square-end-mill-1-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
