With a 5\/8 inch cutting diameter and a 1-1\/4 inch length of cut, this tool removes material efficiently across a range of ferrous and non-ferrous workpieces. The four-flute spiral geometry with a 30-degree helix angle improves chip evacuation and reduces chatter during cuts. A titanium nitride (TiN) finish increases surface hardness and extends tool life under moderate cutting conditions. This end mill is single-end and centercutting, allowing direct plunge entry into the workpiece. It is installed and used by machinists, tool-and-die makers, and CNC operators in job shop and production settings.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits milling, profiling, slotting, and contouring operations on CNC machining centers and manual knee mills. The 5\/8 inch shank diameter fits standard ER collet chucks, end mill holders, and Weldon-style holders commonly found in shop environments. The 3-1\/2 inch overall length provides adequate reach for most standard fixturing setups without sacrificing rigidity. Right-hand cutting direction is the conventional configuration for the majority of CNC vertical and horizontal milling applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for higher rigidity and wear resistance compared to HSS tooling\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle spiral flutes improve chip flow and reduce cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling directly into the workpiece surface\u003c\/li\u003e\n  \u003cli\u003eFour flutes provide a balance of chip clearance and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, single-end configuration — standard orientation for most CNC setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8 inch shank solid carbide square end mill compatible with ER collet systems, end mill holders, and Weldon-style toolholders accepting a 5\/8 inch shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before inserting or removing the end mill. Seat the shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut to avoid premature edge wear or workpiece dimensional errors.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inch (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.48 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: 750219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730473287986,"sku":"750219","price":213.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8ce10b1f79c39a3e5303e7103830de1.jpg?v=1788718074","url":"https:\/\/voomisupply.com\/products\/hertel-750219-square-end-mill-5-8-inch-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
