Built from micrograin carbide with a TiCN (titanium carbonitride) finish, it delivers increased surface hardness and wear resistance compared to uncoated tooling. The 0.5-inch diameter cutter features a 30-degree right-hand spiral flute geometry and a stub-length configuration, with a 0.625-inch length of cut and a 2.5-inch overall length. Centercutting capability allows for plunge entry directly into the workpiece. This tool is intended for installation and use by machinists and CNC operators working in job shop, production, or toolroom environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, peripheral milling, profiling, and plunge operations on a range of ferrous and non-ferrous materials. The stub length reduces overhang, improving rigidity and surface finish in demanding cuts. The 0.5-inch shank diameter fits standard ER collet chucks, end mill holders, and milling machine spindles commonly found in vertical machining centers and manual knee mills. The TiCN coating is particularly effective when cutting alloy steels, stainless steels, cast iron, and hardened materials at elevated cutting speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5-inch mill diameter with a tight tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with a 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiCN finish increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eStub length configuration minimizes deflection in short-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill for standard 1\/2-inch shank milling chucks, ER collet systems, and end mill holders used in vertical machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Before changing tooling, ensure the machine spindle is fully stopped and the power is locked out per standard shop safety procedures. Seat the shank fully into the holder to the minimum insertion depth recommended by the toolholder manufacturer before torquing set screws or collet nuts. Inspect the cutting edges for chips or damage before each use and replace the tool if edge wear is visible.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.625 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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiCN\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: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 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: 750292\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744493240626,"sku":"750292","price":78.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aedcf6ec5aec780b076d10d7b4a5c47b.jpg?v=1788857325","url":"https:\/\/voomisupply.com\/products\/hertel-750292-square-end-mill-1-2-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
