Sandvik Coromant 5740461 Milling Insert Rckt 2040 Carbide

Product Description

The SANDVIK COROMANT 5740461 is a round solid carbide milling insert in the RCKT series, designed for face and shoulder milling operations on steel, stainless steel, and superalloy and titanium workpiece materials. Running in grade 2040 with a multilayer CVD coating of TiCrN, Al2O3, and TiN, this insert delivers wear resistance and thermal stability in demanding cutting environments. It features a 12 mm inscribed circle, a 0.1875-inch thickness, and a positive rake geometry with 7-degree relief angle. The insert holds 8 cutting edges and uses a screw-clamping method for secure tool holding. Licensed HVAC and metalworking shops and machining professionals are the primary installers and users of this insert.

This insert is suited for single-sided use in milling applications involving steel (P45 material grade), stainless steel (M40), and superalloys and titanium (S30). It carries the ANSI and ISO designations RCKT 12 04 M0-MM 2040 and is compatible with SRSC and SRDC cutter series. The MM chip breaker geometry supports medium machining conditions. Maximum depth of cut is 1.76 mm (0.0693 inches), making it appropriate for finishing and semi-finishing passes. Typical applications include face milling, copy milling, and multi-axis contouring on CNC machining centers.

Key Features

• CVD multilayer coating: TiCrN, Al2O3, and TiN for heat and wear resistance
• Positive rake, 7-degree relief angle geometry reduces cutting forces
• MM chip breaker suited for medium cutting conditions on steel and stainless
• Compatible with SRSC and SRDC cutter series for flexible tooling setups
• Neutral hand orientation supports multi-directional cutting paths

Compatibility

Compatible with SRSC and SRDC cutter series. Designated for use with ANSI and ISO tool systems under code RCKT 12 04 M0-MM 2040. Intended for machining steel, stainless steel, and superalloys and titanium workpiece materials.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the manufacturer-specified procedure without overtightening, as this can fracture the carbide insert. Inspect the insert pocket and seat for debris or damage before mounting a new insert.
