Ground from M7 high speed steel and left uncoated, it runs well in shops where regrinding is routine. The tool measures 0.625 inches in diameter with a 1.125-inch length of cut and a 0.500-inch straight shank. Overall length is 3.125 inches. The 30-degree right-hand spiral flute geometry promotes chip evacuation and reduces cutting forces across a range of conventional milling operations. Centercutting geometry allows direct plunge entry without a pre-drilled hole.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for manual mills, CNC machining centers, and knee mills running conventional or climb milling passes. Regular-length classification makes it a practical choice for shoulder milling, slotting, and light profiling cuts in mild steel, tool steel, aluminum, and similar workpiece materials. The 0.500-inch shank fits standard ER32, R8, and CAT40 or BT40 toolholders commonly found in job shops and maintenance environments. It is sold individually and is appropriate for machinists, tool-and-die makers, and maintenance technicians who need a reliable HSS option at standard reach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness and regrindability\u003c\/li\u003e\n\u003cli\u003e2 right-hand spiral flutes with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003e0.500-inch straight shank fits standard ER, R8, and taper toolholders\u003c\/li\u003e\n\u003cli\u003eUncoated finish simplifies resharpening in-house\u003c\/li\u003e\n\u003cli\u003eRegular length classification balances rigidity and reach for general work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank HSS square end mill for use in any milling machine or machining center accepting a 0.500-inch straight shank toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and torque the toolholder according to the machine tool and toolholder manufacturer specifications before use. Verify runout with a dial indicator after clamping to minimize premature edge wear. HSS end mills are sensitive to excessive feed rates and interrupted cuts without adequate rigidity — ensure the workpiece and fixture are secure before cutting. Cutting fluid or mist coolant is recommended when machining steel to extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches (1.1250 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\/8 inches (3.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: 0.175 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: E1030902\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733774139698,"sku":"E1030902","price":59.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b315dbb3687ac4d76e8619ab5689a6c0.jpg?v=1788759144","url":"https:\/\/voomisupply.com\/products\/hertel-e1030902-square-end-mill-5-8-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
