It carries a 0.125 inch cutting diameter, a 0.375 inch length of cut, and a 0.375 inch shank diameter, with an overall length of 2.3125 inches. The two-flute, single-end geometry is center-cutting, meaning it can plunge directly into a workpiece as well as cut laterally. It is sized for precision profiling, slotting, and pocketing passes in ferrous and non-ferrous materials. Machinists and toolroom technicians select cobalt grades when tool life in stainless steel, alloy steel, and high-temp alloys is a priority over uncoated HSS options.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited to manual knee mills, CNC machining centers, and tool-and-die work where a small-diameter cutter is required for detail features, narrow slots, or finish passes. The 0.125 inch diameter makes it a common choice for fine-feature work in mold making, fixture fabrication, and precision part machining. The TiCN coating adds surface hardness and reduces friction, extending tool life in interrupted cuts and abrasive materials. The straight 0.375 inch shank fits standard R8, ER, and Weldon-style collet chucks commonly found in job shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN finish increases surface hardness and reduces built-up edge in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry provides good chip clearance in slots and pockets\u003c\/li\u003e\n  \u003cli\u003e0.125 inch cutting diameter suited for fine-detail and small-feature machining\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration; 0.375 inch shank fits widely available collet and chuck systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank square end mill with a 0.375 inch diameter shank, compatible with ER collet chucks, R8 collets, and Weldon-style side-lock holders sized for 3\/8 inch shanks on vertical mills and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes must be performed with the spindle fully stopped and the machine in a locked-out, de-energized state per applicable OSHA lockout\/tagout procedures. Verify collet or chuck runout before cutting to protect this small-diameter tool from deflection-related breakage. Follow the machine tool manufacturer and tooling manufacturer feed and speed recommendations for the specific workpiece material. Inspect the cutting edges before each use; discard or resharpen any tool showing chipping or coating delamination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.3125 inches (2-5\/16 inch)\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 HSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: E7030008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737309970738,"sku":"E7030008","price":33.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a0d5657ad26e47866d8008170ed4221.jpg?v=1788786928","url":"https:\/\/voomisupply.com\/products\/hertel-e7030008-square-end-mill-0-125-in-2-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
