It features a 1\/2 inch cutting diameter, a 0.015 inch corner radius, and a 1-1\/2 inch length of cut, making it well-suited for both roughing and finishing passes in a single tool. The DLC (Diamond-Like Carbon) PVD coating reduces friction and built-up edge when cutting aluminum, copper, brass, and similar materials. Three right-hand spiral flutes with a coarse pitch promote efficient chip evacuation. The extended reach design and straight-cylindrical shank fit standard toolholders used on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use on non-ferrous workpieces in both production shop and job shop environments. The center-cutting geometry allows plunge entry as well as conventional and climb milling. The medium-length flute classification and 1-1\/2 inch reach length make it appropriate for pocketing, slotting, and contouring operations where a full 4 inch overall length provides clearance over deep setups or fixture components. It is used by machinists and CNC programmers working with aluminum alloys, copper, composites, and other N-category materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.015 inch corner radius protects the cutting edge and improves surface finish at part corners\u003c\/li\u003e\n\u003cli\u003eDLC PVD coating reduces friction and adhesion on non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eThree right-hand spiral flutes with coarse pitch for aggressive chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting end geometry allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eExtended reach with 1-1\/2 inch reach length suits deep pockets and tall fixtures\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade provides rigidity and wear resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-cylindrical toolholders accepting a 1\/2 inch shank.
