Built from M7 high speed steel, it features a 15\/32 inch (0.4688 inch) cutting diameter, a 1-1\/4 inch length of cut, and a 1\/2 inch shank diameter for secure tool-holder engagement. The 30-degree spiral flute geometry promotes efficient chip evacuation and smooth cutting action. This is a right-hand cut, right-hand flute configuration with centercutting capability, allowing plunge entry into workpieces. It ships uncoated and is suited for manual or CNC milling applications where HSS tooling is appropriate. Machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard 1\/2 inch collets and end mill holders used on vertical milling machines, knee mills, and CNC machining centers. The 3-1\/4 inch overall length provides adequate reach for most standard cavity and profile milling work without excessive overhang. The centercutting design supports slot milling, pocket milling, and ramp entry cuts. It is intended for use on steel, cast iron, aluminum, and similar machinable materials at appropriate feeds and speeds for HSS tooling. No extended reach is provided, keeping deflection minimal at this length.\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 ferrous materials\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge and slot milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle setups\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with cutting fluids on a wide range of materials\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch shank diameter fits common collet and end mill holder standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for 1\/2 inch end mill holders, collet chucks, and Weldon-style tool holders on standard vertical milling machines and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove end mills with the spindle fully powered off and locked out per applicable machine safety procedures. Seat the shank fully into the holder to the recommended engagement depth before tightening set screws or collet nuts to the tool holder specification. Inspect the cutting edges for chips or wear before each use. Always select feeds, speeds, and depth of cut appropriate for M7 HSS tooling and the workpiece material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 15\/32 inch (0.4688 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/4 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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 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: E1039030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746324021554,"sku":"E1039030","price":60.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/956c1df910a906e114b0f0330f940f3f.jpg?v=1788868361","url":"https:\/\/voomisupply.com\/products\/hertel-e1039030-square-end-mill-15-32-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
