It is designed for milling slots, shoulders, and peripheral cuts in a wide range of ferrous and non-ferrous materials. The tool features a 30-degree helix angle with a spiral flute geometry, right-hand cut, and right-hand flute orientation. Cutting diameter is 0.2813 inches (9\/32 inch) with a 3\/8 inch shank diameter and a 2-1\/2 inch overall length. This end mill is uncoated and non-centercutting, making it suited for side milling and slotting operations where plunge entry is not required.\u003c\/p\u003e\u003cp\u003eThis end mill is used in manual knee mills, CNC machining centers, and toolroom mills handling general-purpose material removal. The 5\/8 inch length of cut accommodates typical slotting and profiling depths in light-to-medium stock. It is installed and used by machinists and tool-and-die professionals in job shop, maintenance, and production environments. The 3\/8 inch shank fits standard ER collet chucks, end mill holders, and Weldon-style side-lock holders commonly found in machine shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction provides toughness and wear resistance for general-purpose machining\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip evacuation during side milling and slotting\u003c\/li\u003e\n\u003cli\u003e4-flute design balances material removal rate with chip clearance\u003c\/li\u003e\n\u003cli\u003eUncoated finish allows for easy resharpening and broad material compatibility\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for use in conventional milling setups\u003c\/li\u003e\n\u003cli\u003eNon-centercutting geometry — intended for side milling and slotting, not direct plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank replacement end mill compatible with 3\/8 inch ER collet chucks, end mill holders, and Weldon-style tool holders used in manual and CNC milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the holder to the recommended engagement depth and secure set screws or collet nuts to the tool holder manufacturer's specifications. Verify runout with a dial indicator before beginning cuts, and confirm the non-centercutting geometry is accounted for in the programmed toolpath.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/32 inch (0.2813 inches)\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\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: M7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: E103101801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51750450299186,"sku":"E103101801","price":30.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74f351122817da64fc5dedf48965166d.jpg?v=1788915563","url":"https:\/\/voomisupply.com\/products\/hertel-e103101801-square-end-mill-9-32-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
