Value Collection ICP65050K Turning Insert TCMT21.51 TCN55

Product Description

The VALUE COLLECTION ICP65050K is a solid carbide turning insert designed for use on CNC lathes and manual turning centers. Grade TCN55 carbide with a TiN (titanium nitride) coating provides wear resistance and heat dissipation during metal-cutting operations. The insert follows ANSI code TCMT21.51 and ISO code TCMT110204, both universally recognized designations used by machinists to specify insert geometry. It features a 60-degree triangular shape, a 1/4-inch inscribed circle, a 1/64-inch corner radius, and a 7-degree relief angle. Chip-breaker style T and a screw-holding method make this insert compatible with standard TCMT-style toolholders. Sold individually; minimum order quantity is 10 units.

This insert is suited for turning operations on steel and stainless steel workpiece materials, corresponding to primary material codes M and P. The positive side clearance geometry reduces cutting forces and is appropriate for finishing and semi-finishing passes. Typical applications include OD turning, facing, and light profiling on production lathes in metalworking shops, toolrooms, and manufacturing facilities. Licensed machinists and CNC operators are the primary end users for this type of consumable cutting tool insert.

Key Features

• ANSI grade TCMT21.51 and ISO grade TCMT110204 geometry for broad toolholder compatibility
• Solid carbide construction with TiN coating for extended tool life and heat resistance
• 60-degree triangular insert shape with positive side clearance reduces cutting forces
• 1/64-inch corner radius suited for finishing and semi-finishing operations
• Screw-clamp holding method provides secure, repeatable seating in TCMT-style holders
• Chip-breaker style T controls chip flow in continuous turning operations

Compatibility

Designed as a direct-fit replacement for TCMT21.51-style screw-on turning insert seats; fits standard TCMT toolholders accepting a 1/4-inch inscribed-circle triangular insert with a 0.110-inch hole diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the machine before indexing or replacing inserts. Use the manufacturer-specified torque wrench or key for the clamping screw to ensure proper seating without cracking the insert. Inspect the toolholder pocket and clamping screw for wear or debris before installing a new insert.
