It features a 3\/16 inch cutting diameter with a 5\/8 inch length of cut, a 3\/16 inch shank diameter, and a 2 inch overall length. The micrograin carbide substrate and AlTiN finish provide heat resistance and extended tool life at elevated cutting speeds. A 30-degree spiral helix angle promotes efficient chip evacuation. This end mill is sold individually and intended for use by machinists, tool-and-die makers, and CNC operators working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 750222 is suited for slotting, profiling, and contouring operations on CNC machining centers and manual mills. Its centercutting design allows direct plunge entry without a pre-drilled pilot hole. Right-hand cut and right-hand flute configuration follows standard tooling convention. The regular-length geometry makes it appropriate for general-purpose work where extended reach is not required. The AlTiN coating is well suited to dry or minimal-lubrication cutting strategies in hardened and abrasive materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/16 inch cutting diameter with a mill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit in tight-tolerance work\u003c\/li\u003e\n\u003cli\u003e4-flute configuration balances chip load and surface finish in finish-milling passes\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for high-temperature resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth cutting action and chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank square end mill for use in CNC machining centers, knee mills, and manual milling machines accepting a 3\/16 inch collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in a properly sized collet or end mill holder and torque the retention hardware to the tool holder manufacturer specification. Verify runout with a dial indicator before committing to a production cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 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\u003eFinish\u003c\/strong\u003e: AlTiN\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: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 750222\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732480917810,"sku":"750222","price":32.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/266016d8b4cb5d55dbe87d6ce549a8bf.jpg?v=1788743429","url":"https:\/\/voomisupply.com\/products\/hertel-750222-square-end-mill-3-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
