Sandvik Coromant 5740094 Square-shoulder Face Mill 4in

Product Description

The SANDVIK COROMANT 5740094 is an indexable square-shoulder face mill engineered for precision milling operations in metalworking and machining environments. Built around the CoroMill 245 platform, this cutter accepts 7 inserts of the R245-12T3.. style and delivers a maximum cutting depth of 0.24 inches (6.10 mm) at a 45-degree lead angle with a positive rake geometry. The 4-inch cutting diameter and 1-1/2-inch arbor hole make it a practical choice for medium to large milling setups on machining centers and horizontal mills. Insert retention is handled through a clamp and screw holding method, providing rigid, repeatable tool positioning during high-feed operations. The cutter body is constructed from steel and runs in a right-hand cutting direction.

This face mill is intended for use in production machining environments where square-shoulder profiling, face milling, and shoulder milling operations are performed on ferrous and non-ferrous workpiece materials. The close-pitch configuration with 7 inserts supports higher table feed rates, making it well suited for roughing and semi-finishing passes on components where cycle time and surface quality both matter. It is typically installed on machining centers, CNC horizontal mills, or manual knee mills equipped with a compatible arbor. The CoroMill 245 series is a widely used platform in industrial production and job-shop environments.

• 45-degree lead angle with positive rake geometry for reduced cutting forces
• Clamp and screw insert holding method for secure, repeatable insert seating
• Steel cutter body with right-hand cutting direction
• Maximum depth of cut of 0.24 inches (6.10 mm) per pass
• Overall height of 1.97 inches (50 mm); keyway width of 0.63 inches (16.08 mm)

Compatibility

Compatible with R245-12T3.. series inserts. Cutter style is RA245, part of the SANDVIK COROMANT CoroMill 245 series. Requires a machine spindle or arbor setup with a 1-1/2-inch bore diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Disengage and lock out the spindle drive before mounting or removing the cutter body from the arbor. Verify that all inserts are fully seated and that clamp screws are tightened to the toolholder manufacturer specifications before initiating a cut. Inspect insert edges and clamping hardware for wear or damage at each tool change interval.
