Constructed from micrograin solid carbide and finished with an AlTiN (Aluminum Titanium Nitride) coating, this tool handles elevated cutting temperatures and abrasive workpieces where high-speed steel tooling falls short. The 7\/16 inch cutting diameter pairs with a 30-degree right-hand helix and right-hand cutting direction, promoting efficient chip evacuation and smooth surface finishes. It is center-cutting, allowing direct plunge entry into the workpiece. Machinists and tool-and-die professionals in production and job-shop environments rely on this geometry for reliable results in demanding applications.\u003c\/p\u003e\u003cp\u003eThis end mill suits CNC machining centers and manual knee mills running ferrous alloys, hardened steels, stainless, and high-temp alloys where AlTiN coating provides thermal protection. The 7\/8 inch length of cut accommodates standard slot and peripheral milling depths in this diameter range. The shank diameter matches the cutting diameter at 7\/16 inch, making it compatible with standard ER and end mill holders designed for that bore size. No extended reach is built in, keeping the tool rigid and minimizing deflection at the cutting edge.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating extends tool life in high-temperature and abrasive cutting conditions\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard CNC and manual spindle rotation\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker or variable helix — optimized for consistent, smooth peripheral cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard end mill holders and collet chucks accepting a 7\/16 inch shank diameter, including ER16, ER20, and similarly sized collet systems common to CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill from the holder. Use the appropriate wrench and collet nut torque procedure for the holder type in use — consult the toolholder manufacturer's documentation for specified values. Confirm tool runout with a dial indicator after seating to minimize premature edge wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 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\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (0.875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 750738\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754597417266,"sku":"750738","price":95.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8cfe16d3554ce52d3d54fe586a536913_2ce5c700-3c1a-49ff-8e3d-749c2b19e1bb.jpg?v=1788946978","url":"https:\/\/voomisupply.com\/products\/hertel-750738-square-end-mill-7-16-in-4-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
