Iscar 5510277 TNMG432M3M IC6015 Turning Insert

Product Description

The ISCAR 5510277 is a TNMG432M3M-geometry turning insert in the Isoturn series, manufactured from solid carbide and finished with a CVD-applied TiCN, Al2O3, and TiN multilayer coating. It features a 60-degree triangular shape, a 0.5-inch inscribed circle, and a 1/32-inch (0.0313-inch) corner radius. The insert is 22 mm (0.866 inches) long and 3/16 inch (0.1875 inches) thick. Positive rake geometry and the M3M chip breaker support controlled chip formation during turning operations. This insert is installed by machinists and CNC turning specialists working on precision metal removal applications.

The 5510277 is designed for turning operations on stainless steel workpieces, consistent with ISO material code M. It fits standard TNMG-style toolholders using clamp or pin holding methods. The Isoturn series targets external and internal turning applications where surface finish and tool life on difficult-to-machine materials are priorities. Maximum depth of cut is 5.00 mm (0.197 inches). This insert suits both production and job-shop CNC lathe environments handling austenitic and other stainless steel grades.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal stability on stainless steel
• IC6015 manufacturer grade optimized for stainless steel (ISO M) turning
• Positive rake geometry reduces cutting forces and heat buildup
• M3M chip breaker provides reliable chip control at moderate feeds and depths
• Maximum depth of cut: 5.00 mm (0.197 inches)
• Compatible with clamp and pin holding methods in standard TNMG toolholders
• Conforms to ISO 13399 insert identification standard

Compatibility

Designed as an OEM-specification replacement for TNMG432M3M-style turning inserts used in Isoturn-series toolholders that accept clamp or pin insert retention; verify holder geometry and insert pocket dimensions before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench or insert key specified by the toolholder manufacturer when securing the clamping screw or pin — do not overtighten. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure proper support and prevent premature edge failure.
