Accupro 75356717 VCMT331 Cvd Carbide Turning Insert

Product Description

The ACCUPRO 75356717 is a VCMT-style carbide turning insert designed for precision external turning operations on CNC and manual lathes. Identified by ANSI code VCMT331 and ISO code VCMT160404, this insert features a 35-degree diamond (rhombic) shape with a positive side clearance and a 7-degree relief angle. The CVD coating and ACP25M grade deliver high wear resistance across steel, stainless steel, and cast iron workpiece materials. With a corner radius of 0.0157 inches and a maximum depth of cut of 0.0886 inches, it is suited for finishing and semi-finishing passes where tight tolerances and surface finish quality are the priority.

This insert is appropriate for use in general-purpose turning applications across light manufacturing, job shop, and production environments. It is held in place by a screw-type clamping method and is compatible with standard VCMT-style toolholders. The WSF+ chip breaker geometry helps manage chip formation when machining steel, stainless steel, and cast iron components. Machinists working with ISO P, M, and K material groups will find this insert grade suitable for a range of finishing operations requiring consistent tool life and edge integrity.

Key Features

• ANSI code VCMT331 and ISO code VCMT160404 for direct cross-reference with toolholder systems
• CVD-coated ACP25M carbide grade rated for high wear resistance on steel, stainless steel, and cast iron
• 35-degree diamond insert shape with 7-degree relief angle for positive clearance geometry
• WSF+ chip breaker design for controlled chip formation during finishing and semi-finishing cuts
• 0.0157-inch corner radius suited for blending and finishing passes with tight tolerances
• Screw-type insert holding method for secure, repeatable seating in compatible toolholders

Compatibility

Designed for use in screw-clamped VCMT-style toolholders that accept ANSI size code 331 or ISO size code 160404 inserts. Compatible workpiece material groups include ISO P (steel), M (stainless steel), and K (cast iron).

Installation Notes

Installation is performed by a machinist or toolroom technician using the appropriate torx or hex key to seat the insert securely against the toolholder pocket and clamp screw. Power down and lock out the machine before indexing or replacing the insert. Inspect the toolholder pocket for chips or debris before seating the new insert, as contamination can affect cutting geometry and surface finish. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.
