Accupro 75381780 DNMG110404 Carbide Turning Insert

Product Description

The ACCUPRO 75381780 is a DNMG-style indexable carbide turning insert designed for CNC and manual turning operations on steel, stainless steel, and cast iron workpieces. It features a 55-degree diamond (rhombic) insert shape with a neutral hand orientation and a CVD coating applied over a carbide substrate in grade ACP15K. The corner radius measures 0.40 mm (0.0157 inches), and the insert provides a maximum depth of cut of 2.00 mm (0.0787 inches). With four cutting edges per insert, it delivers extended tool life and consistent performance across a range of turning applications. Licensed machinists and CNC operators are the primary users of this insert.

This insert is suited for medium to finishing turning passes on steel (P), stainless steel (M), and cast iron (K) workpieces. The ACP15K grade with CVD coating targets high wear resistance to moderate wear resistance and toughness across all three material categories. It fits toolholders designed for DNMG-style inserts using clamp, lever lock, pin, or screw holding methods. The WL+ chip breaker geometry supports effective chip control during continuous and light interrupted cuts in these material groups.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench or insert key specified by the toolholder manufacturer when securing the clamping screw or lever — do not over-tighten by hand. Inspect the insert pocket and seating surface for debris or wear before seating the new insert to ensure proper contact and runout.
