Iscar 5507287 DNMG331NF IC9250 Turning Insert

Product Description

The ISCAR 5507287 is a DNMG331NF turning insert in the Isoturn series, manufactured from solid carbide with a CVD-applied TiCN and Al2O3 multilayer coating. The insert carries the IC9250 manufacturer grade and is designed for precision turning operations on stainless steel and steel workpieces. It features a 55-degree diamond shape with a positive rake geometry and a neutral 0-degree relief angle. The inscribed circle measures 3/8 inches, the insert length is 0.458 inches (11.63 mm), and the corner radius is 1/64 inches (0.016 inches). It is held by clamp or pin methods and is suitable for both turning and boring applications.

This insert is intended for use in CNC turning centers and manual lathes where stainless steel and general steel stock are the primary workpiece materials. The NF chip breaker geometry is optimized for finishing and near-finishing cuts, with a maximum depth of cut of 0.118 inches (3.00 mm). It is a multi-use insert applicable to both external turning and boring operations, making it a versatile choice for job shops and production environments running ISO material groups M and P.

Installation Notes

Installation is performed by qualified CNC machinists or tool-room technicians. Power down and lock out the machine spindle before seating or replacing inserts. Ensure the insert pocket and seating surface are clean and free of chips before clamping. Follow the toolholder manufacturer's specified clamping torque and secure the insert using the appropriate clamp or pin hardware for DNMG-style pockets.
