Accupro 75354506 CNMG431 Carbide Turning Insert Cvd

Product Description

The ACCUPRO 75354506 is a CNMG431 style carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It features a C-diamond (rhombic) 80-degree insert shape with a neutral hand orientation and a CVD coating applied over a carbide substrate. The manufacturer grade ACP15K targets high to moderate wear resistance and toughness across steel, stainless steel, and cast iron workpiece materials. With four cutting edges and a 0.40 mm (0.0157 inch) corner radius, this insert delivers consistent tool life and surface finish in production turning applications. It is held in ANSI size code 431 toolholders using clamp, lever lock, pin, or screw methods.

This insert is suited for external and internal turning operations in both light and moderate stock removal passes. The WL+ chip breaker geometry is optimized for general-purpose turning of steel (P), stainless steel (M), and cast iron (K) materials. Typical applications include roughing to semi-finishing passes on production lathes in job shop and manufacturing environments. The 2.00 mm maximum depth of cut makes it appropriate for medium stock removal. Machinists and CNC operators working with P, M, and K workpiece material classifications will find this insert a direct fit for standard CNMG toolholder pockets.

Key Features

Compatibility

Designed as an OEM-style replacement insert for CNMG431 toolholders conforming to ANSI and ISO CNMG120404 standards. Compatible with toolholders using clamp, lever lock, pin, or screw retention methods and accepting an inscribed circle of 0.5000 inches (12.70 mm).

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the spindle powered down and the machine in a safe, locked-out state. Confirm the toolholder pocket, shim, and clamping hardware are clean and free of chips before seating the insert. Torque clamping screws according to the toolholder manufacturer specifications, not insert specifications. Verify depth of cut and feed rate settings do not exceed the maximum depth of cut of 2.00 mm before resuming cutting operations.
