Built from M7 high speed steel with a bright, uncoated finish, this single-end mill features a 3\/8-inch diameter cutting edge and a 42-degree helix angle that promotes chip evacuation and smooth cutting action. With an extra-long 2-1\/2-inch length of cut, it handles deep-pocket milling and slotting work that standard-length end mills cannot reach. Two right-hand spiral flutes and a centercutting geometry allow plunge entry as well as peripheral and slot cutting. It is sized for use in standard 3\/8-inch collets and end mill holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for ferrous and non-ferrous metal milling in manual knee mills, CNC machining centers, and milling attachments on lathes. The extra-long length of cut makes it a practical choice for deep cavity work, long-reach profiling, and slotting operations where shorter tooling would not clear the workpiece. Machinists, tool and die makers, and maintenance technicians performing in-shop fabrication are the primary installers and users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction for toughness and wear resistance in general-purpose machining\u003c\/li\u003e\n  \u003cli\u003e42-degree helix angle promotes efficient chip evacuation in deep cuts\u003c\/li\u003e\n  \u003cli\u003eExtra-long 2-1\/2-inch length of cut for deep-pocket and long-reach applications\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluid on a range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any milling machine or CNC machining center equipped with a 3\/8-inch collet, end mill holder, or equivalent toolholding system that accepts a 3\/8-inch shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this end mill should be performed by qualified machinists familiar with milling machine operation and toolholding practices. Ensure the spindle is fully stopped and machine power is locked out before installing or changing tooling. Verify the collet or holder is rated for the shank diameter and that runout is within acceptable limits before cutting. Always use appropriate cutting fluid and start at conservative feed and speed settings when first engaging a new end mill in a given material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\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: 2-1\/2 inches (2.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/4 inches (4.25 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel, Grade M7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle\/Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0048 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: E107202401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730760761650,"sku":"E107202401","price":51.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82c84a863f0cacb6e2bd666f4f241113.jpg?v=1788722401","url":"https:\/\/voomisupply.com\/products\/hertel-e107202401-square-end-mill-3-8-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
