It carries a 9\/32-inch (0.2813-inch) cutting diameter with a 3\/4-inch length of cut and mounts on a 3\/8-inch straight shank. Overall length is 2.5 inches. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation while the centercutting design allows plunge entry directly into the workpiece. Machinists and tool-and-die professionals use this mill for slotting, profiling, and pocket milling in ferrous and non-ferrous materials on manual mills and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for general-purpose milling applications in job shops, maintenance environments, and production settings. Its M7 HSS construction provides good toughness and wear resistance at moderate cutting speeds. The uncoated finish makes it a cost-effective choice for lower-speed operations or when re-sharpening is anticipated. Right-hand cut and right-hand flute orientation are standard for conventional spindle setups. Typical applications include contouring, side milling, and full-slot cuts in steel, aluminum, brass, and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness and re-sharpenability\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge cuts without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced cutting force\u003c\/li\u003e\n\u003cli\u003e4 flutes provide a good balance of chip clearance and surface finish\u003c\/li\u003e\n\u003cli\u003eSpiral flute geometry for consistent contact and stable cutting action\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute — compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or working-stock square end mill for standard 3\/8-inch collet or end mill holder setups on manual vertical mills and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist with the spindle fully stopped and locked out before changing tooling. Seat the shank fully into a properly sized collet or end mill holder and torque the retention mechanism per the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut. Do not exceed the recommended depth of cut for the diameter and material combination in use.\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: 3\/4 inch (0.7500 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: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\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\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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Single End\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: E103901801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729510072626,"sku":"E103901801","price":42.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/105a2e60989aa751e2a4caa9754141be.jpg?v=1788705458","url":"https:\/\/voomisupply.com\/products\/hertel-e103901801-square-end-mill-9-32-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
