It features a 11\/64 inch (0.1719 inch) cutting diameter with 4 flutes and a 30-degree right-hand helix angle. The flutes run in a spiral configuration, promoting chip evacuation and consistent surface finishes. The tool is centercutting, which allows it to plunge directly into a workpiece in addition to peripheral and slot milling. Manufactured from high speed steel with a bright, uncoated finish, this end mill is suited for low-to-moderate speed machining where HSS tooling is preferred over carbide.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard milling machines, knee mills, CNC machining centers, and manual mills where a 3\/8 inch shank is accepted. With a 1\/2 inch length of cut and a 2-3\/8 inch overall length, it is well-suited for shallow-to-moderate depth slotting, profiling, and contouring work. The uncoated HSS construction makes it easy to resharpen, extending tool life in job shop and maintenance environments where regrinding is common practice.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration for improved surface finish and chip control\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix angle balances cutting forces and evacuation\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction supports resharpening and regrinding\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for a broad range of general-purpose materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard milling machine spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for milling machines and machining centers that accept a 3\/8 inch straight shank end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and the power isolated. Use a properly sized collet or end mill holder rated for the 3\/8 inch shank diameter to ensure secure clamping and runout control. Verify that the tool holder is clean and free of chips before seating the end mill. Consult your machine tool manufacturer guidelines and applicable shop safety standards before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/64 inch (0.1719 inch)\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: High Speed Steel\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 (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 inches (2.3750 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\u003eCoating\u003c\/strong\u003e: Bright\/Uncoated\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: E199921249\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733783707954,"sku":"E199921249","price":27.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0673b65bb7f704c0b5584a572f77cfae.jpg?v=1788759228","url":"https:\/\/voomisupply.com\/products\/hertel-e199921249-square-end-mill-11-64-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
