Accupro 75330910 VCGT331 Carbide Turning Insert

Product Description

The ACCUPRO 75330910 is a VCGT-style carbide turning insert designed for precision metal cutting operations on CNC lathes and turning centers. It carries the ANSI code VCGT331 and ISO code VCGT160404, giving machinists a clear cross-reference for toolholder compatibility. The insert features a V-shaped diamond geometry with a 35-degree included angle and a 7-degree relief angle, which delivers a sharp, free-cutting edge ideal for finishing passes. A polished coating finish and LMF+ chip breaker geometry support consistent chip control at light depths of cut. The 0.0315-inch corner radius and a maximum depth of cut of 0.0531 inches make this insert well-suited for fine finishing work on cast iron and non-ferrous materials.

This insert is applied in turning operations where surface finish and dimensional accuracy are priorities. The ACN15K grade provides high wear resistance appropriate for cast iron (K) and aluminum and non-ferrous (N) workpiece materials. It is a neutral-hand insert, so it mounts in compatible toolholders regardless of cut direction. Typical users include CNC machinists and toolroom operators running production or job-shop turning operations. Each package contains one insert, with a minimum order quantity of 10 units.

Key Features

• ANSI code VCGT331 and ISO code VCGT160404 for direct toolholder cross-reference
• ACN15K carbide grade rated for cast iron and aluminum and non-ferrous materials
• 35-degree diamond (V-shape) geometry with positive side clearance for sharp, low-force cutting
• LMF+ chip breaker designed for light finishing cuts with controlled chip evacuation
• Polished coating finish supports smooth surface finish on finished workpieces
• Screw-lock insert holding method for secure, repeatable seating in the toolholder

Compatibility

Designed as a screw-retained replacement turning insert for VCGT-style toolholders accepting ANSI VCGT331 or ISO VCGT160404 inserts with a 0.1803-inch hole diameter and a 9.53 mm inscribed circle.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Use the correct torque driver for the insert clamping screw — over-tightening can crack the carbide. Inspect the toolholder pocket and seating surfaces for debris or wear before seating the new insert.
