Accupro 75381491 Ccmt Turning Insert Carbide Cvd

Product Description

The ACCUPRO 75381491 is a CCMT-style carbide turning insert designed for precision metal cutting on CNC and manual lathes. It features an 80-degree diamond (rhombic) insert shape with a 7-degree relief angle and a neutral hand orientation, making it suitable for general-purpose turning operations. The insert is CVD-coated in grade ACK20P, which provides high wear resistance when machining steel (P) and cast iron (K) workpiece materials. With a 0.0157-inch (0.40 mm) corner radius and two cutting edges, this insert delivers consistent performance across a range of turning applications.

This insert is intended for use in screw-held CCMT insert toolholders and is well suited for finish to medium turning on steel and cast iron components. The ANSI size code is 21.51 and the ISO size code is 060204. The WM+ chip breaker geometry supports controlled chip evacuation during continuous turning cuts. Machinists and CNC operators in job shops, production facilities, and maintenance environments will find this insert appropriate for general external and internal diameter turning work where wear resistance is the primary concern.

Key Features

• CVD coating in grade ACK20P for high wear resistance on steel and cast iron
• 80-degree diamond (rhombic) insert shape with 7-degree relief angle and positive side clearance
• WM+ chip breaker geometry for controlled chip formation during turning
• Neutral hand orientation compatible with standard CCMT screw-clamp toolholders
• Two usable cutting edges per insert
• 0.0157-inch (0.40 mm) corner radius for general-purpose turning applications

Compatibility

Designed for use in screw-held CCMT-style turning toolholders conforming to ANSI insert code CCMT21.51 and ISO insert code CCMT060204. Primary workpiece material codes P (steel) and K (cast iron).

Installation Notes

Installation is performed by machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder specification; do not overtighten, as this can chip the carbide seat. Inspect the insert pocket and shim seat for damage before seating a new insert.
