Accupro 75473884 CNMG543 Carbide Turning Insert

Product Description

The ACCUPRO 75473884 is a CNMG-style carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It carries the ANSI designation CNMG543 and ISO designation CNMG160612. The insert features an 80-degree diamond (rhombic) shape, a CVD coating applied over a carbide substrate, and a neutral hand orientation. With a corner radius of 1.20 mm (0.0472 inches) and a maximum depth of cut of 8.00 mm (0.315 inches), it is engineered for high wear-resistance in steel and cast iron applications. The grade is ACK20P in the CI series. This insert is sold individually with a minimum order quantity of 10 pieces.

This insert is suited for external and internal turning operations on steel and cast iron workpieces in both production and job-shop environments. The negative side clearance and CNMG geometry make it appropriate for medium to heavy roughing and semi-finishing passes. Machinists and CNC operators working with ferrous materials will find the ACK20P grade and 909+ chip breaker geometry effective across a range of cutting conditions. Four available cutting edges extend tool life and reduce per-edge tooling cost.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom personnel. Power down and lock out the spindle before seating or indexing any insert. This insert is compatible with clamp, lever lock, pin, and screw holding methods per the toolholder design in use. Inspect the toolholder pocket for wear or damage before seating a fresh cutting edge, and confirm torque specifications using the toolholder manufacturer documentation.
