Sandvik Coromant 5754297 TNMG544-MR 235 Turning Insert

Product Description

The SANDVIK COROMANT 5754297 is a TNMG544-MR 235 grade solid carbide turning insert designed for precision lathe and turning center applications. It features a triangular insert shape with a 60-degree included angle and a 0-degree relief angle (clearance code N), making it suited for general-purpose external turning, facing, and profiling operations. The insert is coated with TiCN and TiN layers for improved wear resistance and tool life across a range of workpiece materials. At 1.0195 inches in length with a 5/8-inch inscribed circle, this insert fits standard TNMG-style toolholders used in production and job-shop environments. Installation is performed by licensed machinists and CNC operators.

This insert is used in external turning and light-duty interrupted cutting applications across both production and job-shop settings. The MR chip breaker geometry is suited for medium-range cutting conditions where controlled chip formation is required. It is compatible with TNMG-style clamping toolholders that accept a 5/8-inch inscribed circle insert with a 1/4-inch hole diameter. The 235 grade designation indicates a CVD-coated carbide substrate optimized for steel and cast iron turning. This insert is sold individually and carries a minimum order quantity of 10 units.

Installation Notes

This insert is installed by machinists or CNC operators using appropriate TNMG insert toolholders. Power down and lock out the machine before changing inserts. Use the correct torque on the clamping screw or pin as specified by the toolholder manufacturer — do not overtighten. Inspect the insert seat for debris or damage before seating a new insert to ensure proper support and cutting geometry.
