Value Collection ICC26852E Turning Insert CNMP542 Carbide

Product Description

The VALUE COLLECTION ICC26852E is a solid carbide turning insert designed for precision lathe and turning center operations. Manufactured to ANSI insert code CNMP542 and ISO code CNMP160608, this insert features an 80-degree diamond (rhombic) shape with a negative side clearance and a bright, uncoated finish classified as grade I22. The 5/8-inch inscribed circle and 1/32-inch corner radius make it well suited for moderate to heavy material removal passes. Installed by machinists and CNC operators, this insert is a direct drop-in for compatible CNMP-style toolholders.

This insert is intended for use in turning applications involving workpiece material groups K (cast iron), M (stainless steel), N (non-ferrous metals), and S (superalloys and high-temperature alloys). The chip breaker style is P, which is designed to manage chip control in continuous cutting passes. Typical applications include external turning and finish-to-rough operations on CNC lathes and manual engine lathes in production machining environments.

Key Features

• 80-degree diamond (rhombic) insert shape for versatile turning geometry
• Solid carbide construction, material grade C2, with bright uncoated finish for non-ferrous and cast iron work
• 5/8-inch (0.6250 inch) inscribed circle for substantial depth-of-cut capability
• 1/32-inch (0.0313 inch) corner radius for controlled surface finish
• Negative side clearance (N clearance code) with clamp and pin holding method for rigid seating
• P-style chip breaker for effective chip management during continuous cuts

Compatibility

Designed as an OEM-style replacement for CNMP-style toolholders accepting ANSI size code 542 inserts with a 1/4-inch hole diameter and negative rake geometry. Compatible with workpiece material groups K, M, N, and S per the primary workpiece material codes listed by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine fully powered down and the spindle locked before indexing or replacing inserts. Use appropriate insert seating tools and confirm the clamp and pin holding mechanism is fully engaged before resuming cuts. Follow the toolholder manufacturer torque guidelines for clamping screws. Always wear appropriate PPE when handling carbide inserts due to sharp cutting edges.
