Iscar 5550447 Turning Insert TCMT22SM IC807 Solid Carbide

Product Description

The ISCAR 5550447 is a solid carbide turning insert in the TCMT22SM geometry, offered under the Isoturn series and coated with TiAlN via a PVD process. The IC807 grade uses a submicron carbide substrate designed to handle interrupted cuts and variable conditions. The insert measures 11 millimeters in length with a 1/4-inch inscribed circle and a 1/32-inch corner radius. The SM chip breaker promotes positive-rake cutting geometry, helping to manage chip formation during turning operations on a range of workpiece materials. This insert is installed by machinists and CNC lathe operators working in production or job-shop environments.

The 5550447 is suited for turning applications on workpiece materials classified under ISO material groups M, P, and S, covering stainless steels, carbon and alloy steels, and superalloys. The triangular insert shape and TCMT style with screw-clamping make it compatible with standard external and light internal turning toolholders. It is appropriate for moderate to finishing depths of cut up to 2.50 millimeters in both general-purpose and precision turning setups on CNC and manual lathes.

Key Features

• IC807 grade with TiAlN PVD coating for wear resistance across multiple ISO material groups
• SM chip breaker with positive rake geometry for controlled chip flow
• 1/32-inch corner radius suitable for finishing and light roughing passes
• Maximum depth of cut of 2.50 millimeters (0.0984 inches)
• Screw-clamping insert holding method for positive seating in the toolholder pocket
• Conforms to ISO 13399 standards for cutting tool data representation

Compatibility

Designed as a TCMT-style screw-on turning insert compatible with external and light internal turning toolholders that accept TCMT geometry with a 1/4-inch inscribed circle. Verify toolholder pocket dimensions against the insert specifications before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and de-energize the machine before indexing or replacing inserts. Use the correct torque screwdriver for the clamping screw to avoid insert seat damage or screw failure. Inspect the toolholder pocket for wear or debris before seating a new insert, and confirm insert orientation matches the intended cutting direction.
