Built from micrograin carbide with a TiCN (Titanium Carbonitride) coating, this tool delivers excellent wear resistance and thermal stability at elevated cutting speeds. It features a 30-degree spiral helix, right-hand cut, and right-hand flute orientation. The centercutting geometry allows plunge entry as well as conventional peripheral milling. With a 7\/32 inch (0.2188 inch) diameter and a 5\/8 inch length of cut, this end mill is suited for slotting, profiling, and contouring in tight-tolerance applications. Machinists and CNC operators in job shops, production facilities, and tool rooms install this type of tooling.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard 1\/4 inch collet chucks and milling tool holders. With a 2-1\/2 inch overall length and a regular-length classification, it is well suited for general-purpose milling work on CNC machining centers and manual knee mills. The TiCN finish adds surface hardness and reduces built-up edge when cutting steels, stainless alloys, and cast iron. The spiral flute design promotes efficient chip evacuation, reducing heat buildup and extending tool life in continuous cutting operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves wear resistance and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e4-flute, 30-degree helix spiral configuration for smooth chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting capable — supports both plunge and ramp entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.000 \/ -0.002 inches for consistent fitment in precision work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/4 inch collet systems and milling tool holders on CNC machining centers and manual milling machines requiring a 7\/32 inch diameter square end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the end mill. Secure the shank to the full recommended engagement depth in the collet or tool holder, and verify runout with a dial indicator before beginning a cut. Follow the tooling manufacturer and machine builder guidelines for speeds, feeds, and depth-of-cut parameters appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/32 inch (0.2188 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/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\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.06 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: 750690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51751403913522,"sku":"750690","price":44.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00d1e83724afc3322888eb44365eff6e.jpg?v=1788923282","url":"https:\/\/voomisupply.com\/products\/hertel-750690-square-end-mill-7-32-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
