Built from M42 cobalt high-speed steel, it delivers heat and wear resistance suited to interrupted cuts, harder steels, and demanding shop floor conditions. The cutter features a 0.75 inch mill diameter, a 1.3125 inch length of cut, and a 5\/8 inch shank diameter, making it a regular-length tool with balanced rigidity and reach. The 30-degree spiral flute geometry promotes efficient chip evacuation and smooth cutting action. This uncoated end mill ships ready to run and is installed by machinists and tool-and-die professionals on vertical mills, knee mills, and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling operations in a wide range of shop environments, including job shops, maintenance and repair operations, and production machining. The centercutting design allows direct plunge entry, adding flexibility for pocketing and ramp-entry operations. Right-hand cut and right-hand flute configuration match standard spindle rotation on conventional and CNC vertical milling machines. Its regular length-of-cut range of 1.25 to 1.5 inches keeps deflection low during heavier passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated hot hardness and tool life in difficult-to-machine steels\u003c\/li\u003e\n\u003cli\u003e0.75 inch mill diameter with 1.3125 inch length of cut for standard slotting and profiling depths\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle spiral flutes for smooth cutting action and effective chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge and ramp entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eUncoated finish — ready to run or accepts aftermarket coating for extended life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct application cobalt square end mill for use in standard 5\/8 inch collets or end mill holders on vertical and CNC milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the drawbar or collet nut is properly torqued before beginning a cut. Confirm that the 5\/8 inch shank is fully seated in the holder with adequate engagement length to prevent pullout. Follow applicable shop safety procedures and machine manufacturer guidelines when setting feeds, speeds, and depth of cut for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\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\u003eCoating\u003c\/strong\u003e: Uncoated\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: 0.32 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: E2030905\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734562308402,"sku":"E2030905","price":92.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c3fa0b2c353b3edd904ecc0cd2a68fc.jpg?v=1788763486","url":"https:\/\/voomisupply.com\/products\/hertel-e2030905-square-end-mill-0-75-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
