It features a 1.25-inch cutting diameter, a maximum depth of cut of 15.7 mm (0.618 inches), and a 9-inch overall length. The steel body uses a screw-clamped insert holding method and accepts three R390-17.. series inserts. Through-coolant capability supports extended tool life and chip evacuation during demanding cuts. This tool is designed for machinists and CNC operators working in job shops, production machining, and aerospace or general manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for square-shoulder milling, ramping, and slotting operations on machining centers and milling machines. The 90-degree lead angle produces true square shoulders in a single pass. The 1.25-inch cylindrical shank fits standard ER and side-lock toolholders common in CNC setups. With a maximum spindle speed of 9000 RPM, it is appropriate for mid-to-high speed cutting strategies on ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.25-inch cutting diameter with a 90-degree lead angle for true square-shoulder profiling\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 15.7 mm (0.618 inches) per pass\u003c\/li\u003e\n\u003cli\u003eAccepts three R390-17.. indexable inserts secured by screw clamping\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design for improved chip evacuation and insert longevity\u003c\/li\u003e\n\u003cli\u003eRamping-capable end mill type for helical and linear entry strategies\u003c\/li\u003e\n\u003cli\u003eMaximum spindle speed of 9000 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with R390-17.. series indexable inserts.
