Accupro 75354514 CNMG543 Carbide Turning Insert Cvd

Product Description

The ACCUPRO 75354514 is a CNMG-style indexable turning insert manufactured from carbide with a CVD coating. It carries ANSI size code CNMG543 and ISO size code CNMG160612. The insert features a diamond (rhombic) 80-degree included angle, a neutral hand orientation, and a negative side clearance geometry. With four usable cutting edges per insert, it delivers high wear resistance when turning steel (P) and cast iron (K) workpiece materials. The CVD coating, applied under the CI series grade ACK10P designation, supports high-speed, high-wear applications in production turning environments. Licensed machinists and CNC operators are the primary users of this insert.

This insert is suited for external and internal turning operations on steel and cast iron components in both production and job-shop environments. A corner radius of 1.20 mm (0.0472 inches) makes it appropriate for finish to semi-finish turning passes where surface quality and tool life are both priorities. The maximum depth of cut reaches 8.00 mm (0.3150 inches), covering a range from light finishing to moderate roughing cuts. It is compatible with standard CNMG insert toolholders that accept clamp, lever lock, pin, or screw holding methods.

Key Features

• ANSI insert code CNMG543 and ISO insert code CNMG160612 for direct toolholder cross-reference
• Carbide substrate with CVD coating under grade ACK10P for high wear resistance on steel and cast iron
• 80-degree diamond (rhombic) insert shape with negative side clearance for strong cutting edge geometry
• Four cutting edges per insert maximize tooling value in high-volume turning operations
• Corner radius of 1.20 mm (0.0472 inches) suitable for finish and semi-finish turning
• Maximum depth of cut of 8.00 mm (0.3150 inches) supports both finishing and moderate roughing passes
• Chip breaker designation 909+ for controlled chip formation on primary workpiece materials

Compatibility

Designed for use in standard CNMG-style indexable turning toolholders that accept clamp, lever lock, pin, or screw insert holding methods. Tolerance code M and clearance code N apply. Confirm toolholder pocket geometry and clamping style before installation.

Installation Notes

Index or replace this insert with the machine fully stopped and the spindle locked out per your facility lockout/tagout procedure. Use the appropriate torque wrench and insert key specified by the toolholder manufacturer when securing the clamping screw or lever — do not overtighten by hand estimation. Inspect the toolholder pocket for wear, debris, or damage before seating a new insert, as pocket condition directly affects insert stability and tool life. Verify insert orientation and cutting-edge selection before resuming the cut.
