It features a 5\/8-inch mill diameter with a 1-1\/4-inch length of cut and a 3-1\/2-inch overall length. The 4-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN (Titanium Carbonitride) coating increases surface hardness and reduces friction, extending tool life in ferrous and non-ferrous materials. The micrograin carbide substrate provides toughness and wear resistance suited for demanding production environments. Centercutting geometry allows this end mill to plunge directly into a workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling, slotting, profiling, and contouring operations on machining centers and manual mills. The regular-length profile fits standard toolholding systems in job shops, production facilities, and tool-and-die operations. Right-hand cut and right-hand flute orientation are standard for conventional CNC milling setups. The 5\/8-inch shank diameter matches common collet and end mill holder sizes used across vertical and horizontal machining centers. This series is appropriate for machinists and CNC operators working with steel, stainless steel, cast iron, and similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases hardness and reduces built-up edge in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design with 30-degree helix angle for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eCentercutting capable — supports direct plunge entry into workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — standard orientation for CNC milling\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.000 \/ -0.001 inches for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill compatible with standard 5\/8-inch collets, end mill holders, and hydraulic toolholders used on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator following the machine tool manufacturer's toolholding torque and runout specifications. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Confirm shank engagement depth meets toolholder minimums to prevent pull-out under cutting loads. Inspect the cutting edges and coating for chips or wear before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches (3.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 404\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: 0.15 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 404-625008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51750215778610,"sku":"404-625008","price":144.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fb2ab6ca234445b5572de1c961d7343.jpg?v=1788914362","url":"https:\/\/voomisupply.com\/products\/osg-404-625008-square-end-mill-5-8-inch-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
