Value Collection ICP77320L Turning Insert CCMT432 TCN55

Product Description

The VALUE COLLECTION ICP77320L is a solid carbide turning insert with a TiN (titanium nitride) coating, designed for external and internal turning operations on CNC lathes and turning centers. Conforming to ANSI insert code CCMT432 and ISO code CCMT120408, it features an 80-degree diamond (rhombic) shape, a 0.5-inch inscribed circle, a 3/16-inch insert thickness, and a 1/32-inch corner radius. The positive side clearance geometry reduces cutting forces and heat buildup, making it well suited for finishing and semi-finishing passes on steel and stainless steel workpieces.

This insert is intended for use in screw-held toolholders compatible with CCMT-style inserts. The CCMT432 form factor is common on medium-duty turning setups in job shops, production machining environments, and tool-and-die operations. Primary workpiece material codes are M and P, indicating suitability for stainless steels and general steels. The TCN55 grade with TiN coating provides wear resistance and extended tool life on these material groups. The chip breaker designation T assists in chip control during continuous turning cuts.

Key Features

• Solid carbide substrate with TiN coating for improved wear resistance on steel and stainless steel
• 80-degree diamond insert shape (CCMT) with positive side clearance for reduced cutting force
• 1/32-inch corner radius suited to finishing and semi-finishing operations
• Screw-held mounting compatible with standard CCMT-style toolholders
• Chip breaker T geometry for effective chip control during continuous cuts
• ANSI code CCMT432 and ISO code CCMT120408 for straightforward toolholder cross-referencing

Compatibility

Designed for use in screw-held toolholders accepting CCMT432 (ISO CCMT120408) style inserts. No specific toolholder model numbers were provided by the manufacturer for this listing.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the machine in a fully stopped and locked-out state. Seat the insert firmly against the toolholder pocket before torquing the clamping screw; refer to the toolholder manufacturer's recommended torque procedure. Inspect the insert pocket for chips or debris before seating a new insert, as contamination can cause insert rocking and premature edge failure. Always verify insert orientation and chip breaker direction relative to the cutting direction before resuming machine operation.
