Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention that standard HSS tools cannot match in demanding cutting conditions. The 0.1875-inch cutting diameter and 2-flute geometry produce clean chip evacuation and smooth surface finishes in both roughing and light finishing passes. With a 30-degree right-hand spiral flute and an uncoated finish, this end mill suits applications where re-sharpening or regrinding is preferred over coated tooling.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for manual mills, CNC machining centers, and knee mills operating at appropriate speeds and feeds for cobalt tooling. The 0.5-inch length of cut handles moderate-depth passes in slots and pockets, while the 1.125-inch reach length allows access to features with slight clearance requirements. Typical users include machinists and tool-and-die professionals working with steel, stainless, cast iron, and similar materials. The 3\/8-inch shank fits standard R8, ER, and side-lock toolholders common in job shop and production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e2-flute design promotes efficient chip clearance in slot milling and plunge applications\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix delivers smooth cutting action and reduced chatter\u003c\/li\u003e\n\u003cli\u003eBall end geometry enables contouring, profiling, and 3D surface work\u003c\/li\u003e\n\u003cli\u003eUncoated finish allows re-sharpening and suits use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eExtended reach configuration with 1.125-inch reach length for added accessibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-end ball end mill with a 3\/8-inch shank diameter, compatible with toolholders sized for 3\/8-inch round shanks including ER collet chucks, set-screw holders, and R8 collet systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist with the machine spindle fully stopped and locked out before tool changes. Ensure the shank is inserted to the full recommended grip depth in the toolholder and that set screws or collet nuts are torqued to the toolholder manufacturer's specification. Verify runout with a dial indicator before cutting, and confirm speeds and feeds are appropriate for M42 cobalt tooling in the specific workpiece material. Never exceed the rated length of cut depth in a single pass without confirming tool deflection is within acceptable limits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.6875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.504 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: E2111012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727515091250,"sku":"E2111012","price":92.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b852a61ae832b362395986490dc1d2c.jpg?v=1788678770","url":"https:\/\/voomisupply.com\/products\/hertel-e2111012-ball-end-mill-0-1875-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
