Built from M42 cobalt high-speed steel, it delivers excellent heat and wear resistance in difficult-to-machine materials including stainless steels, high-temperature alloys, and hardened steels. The 1.125-inch diameter cutter features a 2-flute, right-hand spiral geometry with a 30-degree helix angle, providing a balance of chip clearance and surface finish quality. With a 2.25-inch length of cut and 4.75-inch overall length, this single-end mill is suited for deep-cavity and contour milling applications where reach and rigidity both matter. The uncoated finish makes it straightforward to resharpen in a tool-and-cutter grinding operation.\u003c\/p\u003e\u003cp\u003eThis end mill is used in machining centers, CNC vertical mills, and manual knee mills across job shops, production shops, and toolrooms. Typical applications include profile milling, 3D contouring, slot milling, and die work in ferrous and exotic alloy materials. The 1-inch straight shank fits standard ER or end mill holders in that bore size. It is a single-end tool, meaning the cutting end is not reversible, and it is sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat resistance in tough alloys\u003c\/li\u003e\n\u003cli\u003eBall end geometry enables full-radius cuts, contouring, and 3D surface milling\u003c\/li\u003e\n\u003cli\u003e2-flute right-hand spiral design maximizes chip evacuation in deep cuts\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting efficiency with surface finish\u003c\/li\u003e\n\u003cli\u003eUncoated finish allows straightforward resharpening on standard tool grinders\u003c\/li\u003e\n\u003cli\u003eSingle-end, regular-length configuration for rigid setups in standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-end ball end mill with a 1-inch straight shank, compatible with ER collet chucks, end mill holders, and side-lock holders bored to 1 inch.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully into the holder to the recommended minimum engagement depth per the holder manufacturer's specification and torque the retention hardware according to the holder manufacturer's guidelines. Inspect the cutting edges and shank for damage before each use; do not run a chipped or out-of-round tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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\u003eCoating \/ Finish\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\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: E2110108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749490196786,"sku":"E2110108","price":221.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8350a9581678e9e9c6f7f53c5a218d5.jpg?v=1788906773","url":"https:\/\/voomisupply.com\/products\/hertel-e2110108-ball-end-mill-1-125-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
