Accupro 75552562 Turning Insert CCMT431 Carbide Pvd

Product Description

The ACCUPRO 75552562 is a CCMT-style carbide turning insert designed for external and internal turning operations on CNC and manual lathes. This neutral-hand insert features an 80-degree diamond (rhombic) shape with a 7-degree relief angle and a 0.40 mm (0.0157 inch) corner radius. The ACM25P grade substrate is finished with a PVD coating and a WM+ chip breaker geometry, making it well-suited for steel, stainless steel, and special or super alloys. It is installed and replaced by machinists and CNC operators during routine tooling maintenance or when optimizing for material-specific cutting conditions.

This insert is suited for precision turning on ferrous and difficult-to-machine materials in both production and job-shop environments. The CCMT431 (ISO: CCMT120404) form factor fits standard CCMT-compatible screw-retained toolholders. The WM+ chip breaker geometry supports a range of feed rates and depths of cut, with a maximum depth of cut of 3.00 mm (0.1181 inches). It is appropriate for finishing to semi-finishing passes on steel (P), stainless steel (M), and special or super alloy (S) workpiece materials.

Key Features

• CCMT431 ANSI code, ISO CCMT120404 — fits screw-retained CCMT toolholders
• ACM25P carbide grade with PVD coating for wear resistance across P, M, and S material classes
• WM+ chip breaker geometry supports steel, stainless steel, and special or super alloys
• 80-degree diamond insert shape with positive side clearance for reduced cutting forces
• 0.40 mm corner radius for controlled surface finish in finishing and semi-finishing applications
• Neutral hand — compatible with both left-hand and right-hand toolholder setups
• 2 cutting edges per insert

Compatibility

Designed for use in screw-retained CCMT-compatible toolholders conforming to ANSI size code 431 and ISO size code 120404. Suitable for workpiece materials coded P (steel), M (stainless steel), and S (special and super alloys).

Installation Notes

Installation is performed by machinists or CNC operators. Before seating the insert, confirm the toolholder pocket and screw are clean and free of chips or debris that could affect seating torque and insert stability. Secure the insert using the manufacturer-specified clamping screw for the toolholder — do not overtighten. Always verify insert orientation and hand before resuming cutting operations.
