Sandvik Coromant 5740089 Square-shoulder Face Mill 4in

Product Description

The SANDVIK COROMANT 5740089 is an indexable square-shoulder face mill designed for precision milling operations in metalworking and machining environments. Built on the CoroMill 245 platform, this cutter accepts five R245-12T3 series inserts and delivers a maximum depth of cut of 0.24 inches (6.10 mm) with a 45-degree lead angle and positive rake geometry. The 4-inch maximum cutting diameter and 1-1/2-inch arbor hole diameter make it well-suited for horizontal and vertical milling machines. Installed by machinists and toolroom professionals, this face mill is a direct-fit tool for shops requiring consistent square-shoulder profiles on ferrous and non-ferrous workpieces.

The 5740089 is intended for use in production machining, job shop milling, and toolroom applications where repeatable square-shoulder cuts are required. The CoroMill 245 series is a recognized platform in face milling operations, and this cutter body is sized for mid-range spindle equipment. The right-hand cutting direction and clamp-and-screw insert holding method are standard configurations for this class of milling cutter. No specific compatible machine models or systems beyond the CoroMill 245 series designation are stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool builder's guidelines for arbor mounting and torque procedures.

Verify insert seating and clamp screw engagement before initiating any cutting operation. Keyway alignment with the arbor drive key should be confirmed prior to tightening.
