Accupro 75286633 CNMG433 Carbide Turning Insert Cvd

Product Description

The ACCUPRO 75286633 is a CNMG-style carbide turning insert designed for general-purpose external turning operations on CNC and manual lathes. Identified by ANSI code CNMG433 and ISO code CNMG120412, this insert features a CVD coating applied over a Grade ACP35M carbide substrate for extended tool life across a range of workpiece materials. The insert carries a neutral hand designation, making it compatible with standard CNMG toolholders. With four usable cutting edges and a 1.20 mm (0.0472 inch) corner radius, it delivers consistent performance on steel, stainless steel, and special or super alloys.

This insert is suited for production turning environments where wear resistance and toughness are both required. It is commonly used in light to moderate roughing and finishing passes on steel and stainless workpieces. The WR+ chip breaker geometry helps manage chip flow across varying depths of cut up to 5.00 mm (0.1969 inches). Machinists and CNC operators in job shops, aerospace shops, and general manufacturing facilities will find this insert appropriate for P, M, and S ISO material group applications.

Key Features

• CVD-coated Grade ACP35M carbide substrate for high wear resistance and toughness balance
• CNMG433 / CNMG120412 geometry with 80-degree diamond (rhombic) insert shape
• Four cutting edges with negative side clearance for increased edge strength
• WR+ chip breaker supports steel, stainless steel, and special or super alloy turning
• Maximum depth of cut: 5.00 mm (0.1969 inches)
• Compatible with clamp, lever lock, pin, and screw insert holding methods

Compatibility

Designed as an OEM-style replacement turning insert for CNMG433 / CNMG120412 toolholders accepting negative-rake CNMG inserts with clamp, lever lock, pin, or screw holding systems.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the insert pocket and seating surface are clean and free of chips before securing the insert to prevent microcracking at the cutting edge. Index to a fresh cutting edge at the first sign of wear rather than running the edge to failure to avoid workpiece damage.
