It carries a TiAlN (titanium aluminum nitride) finish that extends tool life by improving heat and wear resistance at elevated cutting speeds. With a 0.5-inch cutting diameter and 1.25-inch length of cut, this end mill is built for roughing passes on ferrous and non-ferrous workpiece materials. The 3-inch overall length and 0.5-inch shank diameter make it compatible with standard milling chucks and collet holders. It is a single-end, centercutting tool with a 30-degree helix angle and right-hand cut and flute direction.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual milling machines in job shop, production, and tool-and-die environments. The roughing geometry reduces cutting forces and chip load per flute, allowing higher feed rates during roughing passes. It is typically installed by machinists performing profile milling, slotting, and pocketing operations where stock removal rate is the priority. The regular-length configuration keeps tool deflection manageable at this diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves thermal resistance and extends tool life at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e4-flute design balances chip evacuation with surface finish during roughing\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix for smooth chip flow and reduced vibration\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration sized for standard 0.5-inch collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production end mill for use in 0.5-inch collet chucks, end mill holders, and milling arbors on CNC and conventional milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine in a full stop and all motion axes locked out. Seat the shank fully into the holder and torque the retention screw or collet nut to the holder manufacturer specification using the appropriate spanner or torque wrench. Inspect the cutting edges and coating for chips or wear before each use. Consult the machine tool builder and cutting tool application data for appropriate speeds and feeds for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5 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\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3 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\u003eEnd Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut Type\u003c\/strong\u003e: Single End, Centercutting\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish \/ Coating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.5 inches L x 0.75 inches W x 0.75 inches H\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HP400-5000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737156845874,"sku":"HP400-5000","price":181.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acf238bc6c8220ff22464e581964884a.jpg?v=1788785022","url":"https:\/\/voomisupply.com\/products\/osg-hp400-5000-roughing-square-end-mill-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
