Accupro 75475046 Turning Insert VNMG331 Cvd Carbide

Product Description

The ACCUPRO 75475046 is a VNMG-style indexable turning insert designed for precision lathe and turning center operations. Built from carbide substrate with a CVD coating, it delivers high wear resistance across a range of cutting conditions. The insert features a 35-degree diamond (rhombic) V-shape with a neutral hand orientation, a corner radius of 0.0315 inches (0.80 mm), and four usable cutting edges. It carries grade ACM20P, suited for steel and stainless steel workpiece materials where wear resistance and moderate toughness are required. Machinists and CNC turning specialists use this insert as a direct replacement or production consumable in high-volume turning applications.

This insert is primarily applied in turning operations on steel (ISO P) and stainless steel (ISO M) workpieces in both production and job-shop environments. The IPK+ chip breaker geometry supports controlled chip evacuation during longitudinal turning, facing, and profiling cuts. The negative side clearance and clamp, lever lock, pin, or screw holding methods make it compatible with standard VNMG toolholders used in CNC lathes and manual turning centers. Maximum depth of cut is 0.1654 inches (4.20 mm), making it appropriate for finishing to medium roughing passes on the materials listed.

Key Features

• CVD-coated carbide substrate in grade ACM20P for high wear resistance on steel and stainless steel
• VNMG insert style with 35-degree included angle V-shape and neutral hand orientation
• Four cutting edges per insert for extended tool life and lower cost-per-edge
• IPK+ chip breaker for controlled chip formation during finishing and medium roughing
• Corner radius of 0.0315 inches (0.80 mm) suitable for moderate surface finish requirements
• Compatible with clamp, lever lock, pin, and screw toolholder holding methods

Compatibility

Designed for use in standard VNMG-style turning toolholders. ANSI insert code VNMG331 and ISO insert code VNMG160404 are the primary designations; the supplier data also references ANSI code VNMG332 and ISO code VNMG160408 as associated standards for this part.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always index or replace the insert with the machine powered down and spindle locked. Use the appropriate torque driver for the selected holding method (clamp, lever lock, pin, or screw) per the toolholder manufacturer specification. Inspect the insert pocket and seating surface for chips or debris before seating a new cutting edge.
