Manufactured from M7 high speed steel in an uncoated finish, it features a 30-degree spiral helix and a right-hand cut with right-hand fluting. The 0.5 inch cutting diameter and 1.25 inch length of cut make it well-suited for slotting, profiling, and peripheral milling. The centercutting geometry allows it to plunge directly into a workpiece without a pre-drilled hole. This tool is installed and operated by machinists and CNC operators in job shop and production settings.\u003c\/p\u003e\n\u003cp\u003eThis end mill is configured for use in conventional milling machines, CNC machining centers, and manual knee mills where a 0.5 inch shank is accepted. The 3.25 inch overall length provides adequate reach for standard-depth setups without excessive overhang. The regular-length designation and spiral flute design support efficient chip evacuation in ferrous and non-ferrous materials. It is sold as a single unit and is appropriate for shops running steel, aluminum, cast iron, and similar machinable alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction for durability in general-purpose cutting applications\u003c\/li\u003e\n  \u003cli\u003e4-flute design balances chip clearance and surface finish quality\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth cutting action and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge entry without pre-drilling\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 in a range of workpiece materials\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 milling machines and machining centers that accept a 0.5 inch straight shank toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall by a qualified machinist or CNC operator using a properly sized collet or end mill holder rated for the 0.5 inch shank diameter. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Minimize tool overhang beyond the holder to reduce vibration and deflection. Verify spindle rotation direction is set to right-hand before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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\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\u003eLength Type\u003c\/strong\u003e: Regular\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: E1039032\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728478306610,"sku":"E1039032","price":40.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1391783a4be9cfdb3ed008c1b7912a26.jpg?v=1788691858","url":"https:\/\/voomisupply.com\/products\/hertel-e1039032-square-end-mill-1-2-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
