It features an 11\/16 inch (0.6875 inch) mill diameter, a 1-1\/2 inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and reduces cutting forces. The TiCN (Titanium Carbonitride) coating increases surface hardness and wear resistance, extending tool life in ferrous and non-ferrous applications. This is a single-end, right-hand cutting, right-hand flute tool manufactured from micrograin solid carbide. It is installed and operated by machinists and CNC tool room technicians.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slot milling, peripheral milling, and profiling operations on machining centers and manual knee mills. The 3\/4 inch shank diameter fits standard ER collet chucks, end mill holders, and shrink-fit toolholders common in production and job shop environments. The regular length profile and centercutting geometry allow both plunge and ramp entry cuts. It is appropriate for use on ferrous metals, stainless steel, and high-temperature alloys where TiCN coating provides a thermal and abrasion advantage over uncoated carbide.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e11\/16 inch mill diameter with a tolerance of +0.000 \/ -0.002 inches for consistent fit and finish\u003c\/li\u003e\n  \u003cli\u003eTiCN coating for improved wear resistance and extended tool life in demanding materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables plunge milling and ramp entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction provides rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute — compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard square end mill for use in CNC machining centers and manual mills accepting a 3\/4 inch shank diameter via ER collet chucks, end mill holders, or shrink-fit tooling systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and torque the toolholder to the spindle according to the machine tool manufacturer specifications before engaging the workpiece.
