Value Collection 2650573 Turning Insert CNMG431 TCN55

Product Description

The VALUE COLLECTION 2650573 is a solid carbide turning insert with a TiN (titanium nitride) coating, designed for general-purpose metal turning operations on CNC lathes and turning centers. Carrying ANSI insert code CNMG431 and ISO insert code CNMG120404, this insert features an 80-degree diamond (rhombic) shape, a negative rake geometry, and a KENLOC series chip breaker profile designated G. The inscribed circle measures 0.5 inches, the insert thickness is 0.1875 inches, and the corner radius is 0.0156 inches (1/64 inch). It is held in place using a clamp and pin method, making it compatible with standard CNMG-style toolholders.

This insert is suited for turning steel (material code P) and stainless steel (material code M) workpieces in both roughing and finishing passes within its rated depth of cut. Typical applications include shaft turning, facing, and profiling on production lathes in job shop and manufacturing environments. The TiN coating improves surface hardness and wear resistance, extending tool life in continuous-cut operations. This insert is sold individually with a minimum order quantity of 10 units.

Key Features

• Solid carbide construction with TiN coating for enhanced wear resistance
• 80-degree diamond (C-shape) insert geometry with negative rake and negative side clearance
• KENLOC series G chip breaker for effective chip control in steel and stainless turning
• Maximum depth of cut: 0.0492 inches (1.25 mm)
• Clamp and pin holding method for secure seating in CNMG-compatible toolholders
• Dual-coded to ANSI (CNMG431) and ISO (CNMG120404) standards for easy cross-referencing

Compatibility

Designed for use in CNMG431-style toolholders that accept clamp and pin insert retention. Suitable for turning steel and stainless steel workpieces as indicated by primary workpiece material codes P and M.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before changing inserts, ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state per facility lockout/tagout procedures. Seat the insert flush against the toolholder pocket and verify clamp and pin engagement before resuming cuts. Do not exceed the rated depth of cut for this insert grade.
