Accupro 75358879 CNMG432 Carbide Turning Insert Cvd

Product Description

The ACCUPRO 75358879 is a CNMG432 indexable carbide turning insert designed for general-purpose external and internal turning operations on CNC and manual lathes. This insert carries an 80-degree diamond (rhombic) shape, a neutral hand orientation, and a CVD coating applied over a carbide substrate. The manufacturer grade is ACP25M, which spans a range from high wear-resistance to high toughness for steel, and from high wear-resistance to moderate wear-resistance and toughness for stainless steel and cast iron. With four available cutting edges per insert, the 75358879 offers cost-effective indexing before replacement is required.

This insert is suited for turning steel, stainless steel, and cast iron workpieces in production and job-shop environments. The WR+ chip breaker geometry helps control chip flow during moderate to aggressive depth-of-cut passes, with a maximum depth of cut of 0.1969 inches (5.00 mm). It is intended for use in toolholders designed to accept CNMG432 inserts using clamp, lever lock, pin, or screw holding methods. Machinists working on P, M, and K material classifications will find this insert applicable across a broad range of turned-part applications.

Key Features

• CNMG432 ANSI insert code, ISO equivalent CNMG120408, for wide toolholder compatibility
• CVD coating on carbide substrate for wear resistance across steel and cast iron applications
• 80-degree diamond insert shape with negative side clearance and neutral hand
• Four cutting edges per insert for maximized indexing value
• WR+ chip breaker geometry supports controlled chip evacuation at moderate-to-aggressive depths
• Maximum depth of cut: 0.1969 inches (5.00 mm)

Compatibility

Designed as an OEM-style replacement turning insert for toolholders accepting CNMG432 geometry with clamp, lever lock, pin, or screw holding methods, conforming to ANSI standard CNMG432 and ISO standard CNMG120408.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and all moving axes secured before indexing or replacing inserts. Ensure the toolholder pocket and seating surface are clean and free of chips before seating the insert. Use the appropriate torque tool for the specific holding method (screw, clamp, or lever lock) as specified by the toolholder manufacturer. Inspect the insert for seating and clamping integrity before resuming cutting operations.
