Ground from M7 high speed steel and left uncoated, this tool provides a durable cutting edge suitable for face milling, slotting, and side milling applications. It features three spiral flutes with a 30-degree helix angle, a 0.75 inch cutting diameter, and a 1.625 inch length of cut. The right-hand cut and right-hand flute configuration follows standard mill setup. Centercutting geometry allows the tool to plunge directly into the workpiece without a pre-drilled entry point.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in manual mills, CNC machining centers, and knee mills where a 0.625 inch shank diameter collet or end mill holder is available. Typical applications include roughing and finishing passes on ferrous and non-ferrous metals in job shop, tool room, and maintenance machining environments. The 3.75 inch overall length provides adequate reach for standard depth setups without excessive overhang. Machinists and tool room operators running general-purpose steel, cast iron, or aluminum work will find the M7 grade appropriate for moderate to high cutting speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle spiral flutes promote chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for general-purpose applications and easy resharpening\u003c\/li\u003e\n\u003cli\u003eThree-flute geometry balances chip load and feed rate flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose square end mill for use with 0.625 inch shank-compatible collets, end mill holders, and tool holders on standard vertical mills and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolroom practices. Ensure the machine spindle is fully stopped and the power is locked out before loading or removing the tool from its holder. Use a properly sized collet or end mill holder to achieve full shank engagement and minimize runout. Follow the tool manufacturer and machine manufacturer guidelines for appropriate speeds and feeds based on workpiece material and depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches (1-5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches (3-3\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\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\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 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: E104394801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737798541618,"sku":"E104394801","price":68.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d19f8888239071bc792e29f994fda34c.jpg?v=1788793678","url":"https:\/\/voomisupply.com\/products\/hertel-e104394801-square-end-mill-3-4-in-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
