Accupro 75381772 Carbide Turning Insert CCMT432

Product Description

The ACCUPRO 75381772 is a carbide turning insert designed for precision metal cutting operations on CNC and manual lathes. Conforming to ANSI insert code CCMT432 and ISO code CCMT120408, this neutral-hand insert features an 80-degree diamond (rhombic) shape with a 7-degree relief angle and a CVD coating applied to ACK20P carbide grade substrate. The 0.80 mm corner radius and positive side clearance geometry suit finishing to moderate roughing passes. With two usable cutting edges per insert, it delivers consistent performance in high-volume turning applications. Machinists and tool-crib professionals rely on this insert format for its repeatable screw-held clamping and standardized sizing.

This insert is suited for turning steel and cast iron workpieces in both production and job-shop environments. The ACK20P grade with CVD coating provides high wear resistance on steel (P-class materials) and a range from high wear resistance to moderate toughness on cast iron (K-class materials). The WM+ chip breaker geometry supports stable chip control across a range of feed rates and depths. Maximum depth of cut reaches 3.00 mm (0.1181 inches), making it appropriate for light roughing through finishing operations on ferrous materials.

Key Features

• CVD-coated ACK20P carbide grade for high wear resistance on steel and cast iron
• CCMT432 / CCMT120408 ANSI and ISO standardized sizing for broad toolholder compatibility
• 80-degree diamond insert shape with positive side clearance for clean entry angles
• WM+ chip breaker for controlled chip evacuation across varied feed and depth conditions
• Two cutting edges per insert for extended tool life per unit
• Screw-held clamping method ensures rigid, repeatable seating in compatible toolholders

Compatibility

Designed as an OEM-style replacement turning insert for CCMT432 or CCMT120408 toolholders with screw-clamp holding systems suitable for steel and cast iron turning applications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key to seat the clamping screw to the toolholder manufacturer's specification — do not overtighten, as this can fracture the insert. Inspect the toolholder pocket and clamp for wear or debris before seating a new insert.
