Built from M42 cobalt high-speed steel, it delivers increased heat and wear resistance compared to standard HSS tooling, making it well suited for harder workpiece materials and interrupted cuts. The cutter features a 0.5 inch diameter, a 1 inch length of cut, and a 4 inch overall length with a 30-degree helix spiral flute geometry. It is centercutting, allowing plunge entry directly into a workpiece. With two flutes and right-hand cut and flute direction, this end mill is a go-to choice for general-purpose milling in a variety of shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in manual mills, CNC machining centers, and knee mills across job shops, maintenance departments, and production facilities. The extended reach design, with a reach length of 2.25 inches, accommodates deeper pockets and shoulder milling where clearance is needed. The 0.5 inch shank diameter fits standard ER collet chucks, end mill holders, and side-lock holders common in both vertical and horizontal milling setups. It is appropriate for milling steel, stainless steel, cast iron, and other ferrous and non-ferrous materials at moderate to aggressive feed rates. Machinists, tool and die makers, and maintenance technicians are the primary installers and operators.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction provides elevated red hardness for cutting harder materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix spiral flute promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute orientation for standard spindle direction\u003c\/li\u003e\n  \u003cli\u003eExtended reach geometry with 2.25 inch reach length for deeper feature access\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for applications where coating is not required or where regrinding is anticipated\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock cutting tool for use in any milling machine spindle accepting a 0.5 inch shank, including ER32 and ER40 collet systems, Weldon side-lock holders, and similar standard end mill toolholders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with end mill toolholding practices. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the full recommended insertion depth in the holder to prevent pullout under cutting load. Follow the machine tool manufacturer and cutting tool manufacturer guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material and operation.\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.25 inches\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: 0.504 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: E299914061\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728689365298,"sku":"E299914061","price":64.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d0887f51a44cd37c933352ddcb98eee.jpg?v=1788695058","url":"https:\/\/voomisupply.com\/products\/hertel-e299914061-square-end-mill-0-5-in-cobalt-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
