Sandvik Coromant 5739381 Square-shoulder Face Mill 2in

Product Description

The SANDVIK COROMANT 5739381 is an indexable square-shoulder face mill designed for high-precision milling operations in metal-cutting applications. Built on the CoroMill Century platform, it features a 90-degree lead angle that produces true square shoulders on workpieces. The cutter accepts 4 inserts of the R590-1105.. style, secured by clamp and screw, and delivers a maximum depth of cut of 11 mm (0.4331 inches). Through-coolant capability supports heat management and chip evacuation during extended cuts. This tool is installed and operated by machinists and CNC programmers working with milling machines in precision manufacturing environments.

This face mill is suited for right-hand cutting operations in both production and job-shop settings where square-shoulder profiling is required. The CoroMill Century series is commonly applied in face milling, shoulder milling, and ramping operations on ferrous and non-ferrous materials. The 2-inch cutting diameter and 3/4-inch arbor hole make it appropriate for mid-range spindle setups on vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully stopped and machine energy isolated per lockout/tagout procedures. Confirm arbor diameter and insert seating before initiating any cut. Inserts must be properly torqued using the manufacturer-specified wrench to prevent movement under load. Through-coolant passages should be cleared and verified before mounting to ensure unobstructed flow during operation.
