With a 3\/4-inch cutting diameter and a 1-1\/2-inch length of cut, this single-end tool is built for material removal in ferrous and non-ferrous applications where tool life and edge integrity are critical. The AlTiN coating provides oxidation resistance and allows operation at elevated cutting temperatures, extending tool life in hard or abrasive workpiece materials. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This end mill is installed and operated by machinists and CNC tooling professionals.\u003c\/p\u003e\u003cp\u003eThis end mill suits vertical machining centers, CNC mills, and manual knee mills requiring a 3\/4-inch shank diameter and 4-inch overall length. It is suited for slotting, profiling, and peripheral milling in production and job-shop environments. The 2-flute configuration is particularly effective in applications where chip clearance is a priority, such as milling softer steels, aluminum alloys, or materials that generate larger chips. Right-hand cut and right-hand flute direction are standard for conventional spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate for high hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated-temperature oxidation resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 3\/4-inch shank diameter for secure toolholder engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard milling chucks, collet holders, and shrink-fit toolholders accepting a 3\/4-inch shank diameter on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and locked out per shop lockout\/tagout procedures. Ensure the toolholder bore and shank are clean and free of chips or burrs before seating the end mill. Proper runout should be verified with a dial indicator before cutting to avoid premature edge wear. Follow machine manufacturer torque specifications for drawbar or collet nut tightening.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (4.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.5 inches L x 0.9 inches W x 0.9 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 750370\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737131254066,"sku":"750370","price":272.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04e58cbfa0e7487aee782b378c67005e.jpg?v=1788784710","url":"https:\/\/voomisupply.com\/products\/hertel-750370-square-end-mill-3-4-in-2-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
