Built from M42 high speed steel with a bright, uncoated finish, this tool delivers consistent performance in general-purpose cutting applications. It features a 15\/64 inch (0.2344 inch) mill diameter, a 1\/2 inch length of cut, and a 3\/8 inch shank diameter. The 30-degree right-hand helix promotes efficient chip evacuation, while the two-flute geometry provides adequate chip clearance for slotting and profiling cuts. This end mill is installed and used by machinists and tool-and-die professionals working with manual mills and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for light to medium milling tasks including slotting, profiling, and step milling in ferrous and non-ferrous materials. The 2.4375 inch overall length provides adequate reach for standard setups. The bright, uncoated finish makes it appropriate for use in lower-heat applications or where coolant is applied. Its center-cutting capability allows it to plunge directly into material without a pre-drilled entry point, adding versatility across a range of job-shop and production machining scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 high speed steel construction for durability in general-purpose machining\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix promotes efficient chip evacuation during cutting\u003c\/li\u003e\n\u003cli\u003eTwo-flute geometry provides maximum chip clearance in slotting operations\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluids or coolant\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank end mill for use in collet chucks, end mill holders, or milling machine spindles accepting a 3\/8 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the tool holder to the recommended engagement depth for your holder type, leaving no less than the minimum shank engagement to prevent pullout. Follow machine manufacturer guidelines and applicable shop safety procedures when setting tool length offsets and spindle speeds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 15\/64 inch (0.2344 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/16 inches (2.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\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\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: E299921148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748676796722,"sku":"E299921148","price":48.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4a6d916eaa0b8d22072de67f36ef74c_8b0d748e-8f0e-496d-910d-6e3ef399b1fb.jpg?v=1788896541","url":"https:\/\/voomisupply.com\/products\/hertel-e299921148-square-end-mill-15-64-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
