Accupro 75297655 CNMG432 Carbide Turning Insert Cvd

Product Description

The ACCUPRO 75297655 is a CNMG432 indexable carbide turning insert designed for external turning operations on CNC and manual lathes. Built to ANSI code CNMG432 and ISO code CNMG120408, this insert features an 80-degree diamond (rhombic) shape with a neutral hand orientation and four usable cutting edges. The CVD coating on the ACP15K carbide grade delivers high wear resistance with balanced toughness, making it well suited for continuous and interrupted cuts on steel, stainless steel, and cast iron. The 0.0315-inch corner radius and negative side clearance (clearance code N) support stable, predictable chip control in production turning environments. Machinists and CNC operators install this insert as part of a standard CNMG toolholder system.

This insert is intended for use in production and job-shop turning applications across a range of workpiece materials. Primary workpiece material codes P, M, and K confirm suitability for steel, stainless steel, and cast iron respectively. The WL+ chip breaker geometry supports general-purpose turning with moderate to high wear resistance demands. Maximum depth of cut is 2.00 mm (0.0787 inches), making this insert appropriate for finishing and semi-finishing passes. It is compatible with clamp, lever lock, pin, and screw insert-holding methods, giving it broad toolholder compatibility in both manual and automated turning setups.

Key Features

• ANSI code CNMG432, ISO code CNMG120408 for direct drop-in replacement in standard CNMG toolholders
• CVD-coated ACP15K carbide grade for high wear resistance with adequate toughness across P, M, and K workpiece materials
• Four cutting edges per insert reduce per-edge tooling cost in high-volume turning
• 80-degree diamond insert shape (shape code C) provides a strong cutting edge with good accessibility
• WL+ chip breaker geometry for controlled chip formation on finishing and semi-finishing passes
• Compatible with clamp, lever lock, pin, and screw clamping methods for flexible toolholder use

Compatibility

Designed as a direct OEM-style replacement for standard CNMG432 toolholder seats using clamp, lever lock, pin, or screw holding methods. No specific machine or toolholder model numbers were provided in the product data.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine before indexing or replacing inserts. Use the correct torque wrench and insert key for the specific clamping system to avoid cracking the carbide substrate. Inspect the insert pocket and seating surface for chips or debris before installing a new insert edge.
