Accupro 75550152 CNMG432 Carbide Turning Insert ACP35M

Product Description

The ACCUPRO 75550152 is a CNMG432 carbide turning insert designed for general and demanding turning operations on CNC and manual lathes. It features a CVD coating and ACP35M grade carbide substrate, delivering a balance of wear resistance and toughness suited for steel, stainless steel, and special or super alloy workpieces. The 80-degree diamond (rhombic) insert shape provides strong cutting edge geometry, and the WM+ chip breaker promotes reliable chip control across a range of cutting conditions. With a corner radius of 0.0315 inches (0.80 mm) and a maximum depth of cut of 0.1575 inches (4.00 mm), this insert covers a practical range of finish and semi-finish turning passes. Machinists and CNC operators install this insert as a direct replacement or fresh tooling in standard CNMG-compatible toolholders.

This insert is suited for turning applications on steel (ISO P), stainless steel (ISO M), and special and super alloys (ISO S). It performs in both production and job shop environments where consistent tool life and predictable chip breaking are priorities. Typical applications include external and internal turning, facing, and profiling operations on horizontal and vertical turning centers. The neutral hand orientation makes it adaptable to a wide variety of toolholder configurations.

Key Features

• CVD-coated ACP35M carbide grade for high wear resistance and toughness across P, M, and S workpiece materials
• CNMG432 geometry with 80-degree diamond insert shape and negative side clearance for strong edge support
• WM+ chip breaker for reliable chip control during steel and stainless turning
• Corner radius of 0.0315 inches (0.80 mm) suitable for finish and semi-finish turning
• Maximum depth of cut of 0.1575 inches (4.00 mm)
• 4 cutting edges per insert for extended tooling economy
• Compatible with clamp, lever lock, pin, and screw insert holding methods

Compatibility

Designed for use in standard CNMG432 (ISO CNMG120408) compatible toolholders accepting negative-rake, 80-degree diamond inserts with a 0.2043-inch hole diameter and a 0.5000-inch inscribed circle.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians following the toolholder manufacturer's clamping procedure. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque wrench and fastener type specified by the toolholder manufacturer — do not overtighten screw or lever lock mechanisms. Inspect the insert pocket for damage or debris before seating a new cutting edge.
