The tool features a 0.5 inch cutting diameter, a 2 inch length of cut, and a 4 inch overall length on a 0.5 inch shank. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation and surface finish quality. The TiCN coating increases surface hardness and wear resistance compared to uncoated carbide, extending tool life in demanding cutting conditions. Micrograin carbide construction provides the toughness and edge retention required for consistent results in production environments. This end mill is installed and operated by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThe 750240 is suited for slotting, profiling, and peripheral milling in ferrous metals, alloy steels, stainless steel, cast iron, and similar materials where TiCN-coated carbide delivers reliable performance. The long length-of-cut classification at 2 inches supports deeper axial engagement when workpiece geometry or fixture clearance requires it. The centercutting geometry allows for plunge entry directly into the workpiece without a pre-drilled starting hole. Right-hand cut and right-hand flute configuration is standard for conventional and climb milling on vertical and horizontal machining centers as well as manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves wear resistance and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e30-degree helix spiral flute design promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard machining center spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eLong length-of-cut classification supports deeper axial passes where required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 0.5 inch shank square end mill compatible with ER collet chucks, end mill holders, and hydraulic toolholders sized for 0.5 inch straight shanks on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the toolholder. Verify collet or holder bore size matches the 0.5 inch shank diameter and that the tool is seated to the correct gauge length before tightening. Do not exceed the toolholder manufacturer's recommended clamping torque range for this shank diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753205596466,"sku":"750240","price":127.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1602d4137deb95d7acfeac1d9d3949b6.jpg?v=1788933869","url":"https:\/\/voomisupply.com\/products\/hertel-750240-square-end-mill-1-2-in-4-flute-solid-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
