Built with six flutes and an AlTiN+ coating, it is engineered for cutting high-temperature alloys and other difficult-to-machine materials where heat resistance and edge retention are critical. The variable helix angle, ranging from 36 to 40 degrees, and variable index geometry reduce harmonic vibration during cutting, improving surface finish and tool life. This is a single-end, right-hand cutting tool with a 3\/8 inch diameter and a 1.0 inch length of cut, making it suitable for finishing and semi-finishing passes in milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills across aerospace, defense, and industrial manufacturing environments where high-temp alloys such as Inconel, titanium, and similar superalloys are common workpiece materials. The centercutting design allows for plunge entry as well as conventional peripheral milling. It is typically selected by machinists and CNC programmers when toolpath stability and thermal resistance are prioritized over high-feed roughing strategies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN+ coating provides high oxidation resistance and hardness at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduce chatter and improve surface finish\u003c\/li\u003e\n\u003cli\u003eSix flutes increase material removal rate compared to standard four-flute designs\u003c\/li\u003e\n\u003cli\u003eCentercutting construction enables plunge milling entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for machining high-temperature alloys (workpiece material code S), this end mill is suited for applications where AlTiN+ coated solid carbide tooling is specified.
