With a 3\/4-inch mill diameter, 3-inch length of cut, and four flutes, this tool delivers consistent chip evacuation and surface finish across a range of milling operations. The 30-degree helix angle balances cutting force with material removal rate. A TiN (titanium nitride) coating adds surface hardness and reduces friction at the cutting edge, extending tool life in production environments. This end mill is intended for use by machinists and tool-room professionals working on CNC or manual milling machines.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for peripheral milling, slotting, profiling, and general-purpose material removal in job shop and production machining environments. The centercutting geometry allows plunge entry, adding flexibility in programming and setup. With a 6-inch overall length and 3\/4-inch shank diameter, the tool fits standard R8, CAT, BT, and HSK toolholders sized for 3\/4-inch shanks. Applications span roughing and semi-finishing passes in steel, stainless, cast iron, and similar workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-inch mill diameter with matching 3\/4-inch shank for rigid tool holding\u003c\/li\u003e\n\u003cli\u003e3-inch length of cut supports deep peripheral passes without tool change\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for balanced cutting forces and efficient chip flow\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces wear and extends tool life in production milling\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for CNC and manual milling machine setups accepting a 3\/4-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following machine tool manufacturer guidelines. Secure the shank in a properly sized collet, end mill holder, or shrink-fit toolholder torqued to the spindle manufacturer specification before operation. Inspect the tool holder bore and shank for contamination or runout before clamping. Never exceed the spindle RPM or axial depth-of-cut limits established in the machining program for the selected material.\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: 3 inches (3.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (6.0000 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: 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\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: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 1.18 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: 750238\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727532982578,"sku":"750238","price":432.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab27b4ca3904827d15800a692bf08085.jpg?v=1788678953","url":"https:\/\/voomisupply.com\/products\/hertel-750238-square-end-mill-3-4-in-4-flute-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
