With a 0.5-inch cutting diameter and a 2-inch length of cut, this tool handles slotting, profiling, and peripheral milling in a single setup. The four-flute configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. A titanium nitride (TiN) coating adds surface hardness and lubricity, extending tool life in ferrous and non-ferrous materials. This end mill is designed for installation in machining centers, CNC mills, and manual knee mills by machinists and tooling technicians.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits production and job-shop environments where consistent geometry and repeatable performance are required. The centercutting design allows plunge entry directly into the workpiece, reducing the need for a pre-drilled pilot hole. Right-hand cut with right-hand spiral flutes makes it compatible with standard spindle rotation on conventional milling equipment. The 0.5-inch shank diameter fits standard ER collets, end mill holders, and Weldon-style tool holders commonly found in CNC and manual machine tool setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cutting applications\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eFour flutes with 30-degree helix angle for smooth chip flow and improved finish quality\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without a starter hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for use in standard CNC and manual milling spindles\u003c\/li\u003e\n  \u003cli\u003eSpiral flute design with no chipbreaker for clean, continuous cuts in solid materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide square end mill suitable for use in standard 0.5-inch ER collet chucks, end mill holders, and Weldon-style tool holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before changing tooling. Confirm the shank is fully seated in the tool holder to the recommended gauge-line depth and that the collet or set screw is torqued per the tool holder manufacturer specifications. Inspect the cutting edges for chips or damage before use, and verify spindle speed and feed rate are appropriate for the workpiece material and depth of cut.\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: 2 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: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eVariable Helix\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: 0.34 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: 750255\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746397520178,"sku":"750255","price":117.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/233a62f3804e42961e1431cefd9cef7a.jpg?v=1788869522","url":"https:\/\/voomisupply.com\/products\/hertel-750255-square-end-mill-0-5in-4-flute-solid-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
