Built on the Series 4571 platform, it features a 4 mm cutting diameter, a 0.5 mm corner radius, and four right-hand helical flutes at a 45-degree helix angle. The WXS PVD coating provides enhanced wear resistance and heat dissipation, making this tool suitable for both roughing and finishing operations. Micrograin carbide construction supports rigidity and edge retention at elevated cutting speeds. The extended-reach design with a 3.80 mm neck diameter and 20 mm reach length allows access in deeper or restricted-clearance setups.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for use in CNC machining centers and compatible toolholders across a range of workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The centercutting geometry allows plunge entry, adding versatility for slotting, profiling, and pocket milling operations. The straight-cylindrical 6 mm shank with h6 tolerance ensures secure seating in standard collet and hydraulic toolholders. This tool is appropriate for production shops, tool rooms, and precision job shops working in ISO material groups P, M, K, S, and H.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eWXS PVD coating for superior wear resistance in steel, stainless steel, and hard materials\u003c\/li\u003e\n  \u003cli\u003e0.5 mm corner radius reduces stress concentration and extends tool life at workpiece corners\u003c\/li\u003e\n  \u003cli\u003e45-degree high helix angle improves chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 3.80 mm neck diameter suits restricted-clearance and deep-pocket applications\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance held to 0.00 to -0.02 mm for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with standard toolholders accepting a 6 mm straight-cylindrical shank (h6 tolerance).
