Accupro 75330928 VCGT333 Carbide Turning Insert

Product Description

The ACCUPRO 75330928 is a VCGT-style carbide turning insert designed for precision finishing and semi-finishing operations on cast iron and non-ferrous materials such as aluminum. It carries ANSI insert code VCGT333 and ISO insert code VCGT160412. The insert features a 35-degree diamond (rhombic) shape, a 7-degree relief angle, and a 1.20 mm (0.0472 inch) corner radius. A polished coating finish and LMF+ chip breaker geometry support high wear resistance with moderate toughness. This insert is installed by CNC machinists and toolroom professionals in turning centers and lathes requiring tight tolerances on non-ferrous or cast iron workpieces.

This insert is suited for turning applications on cast iron (ISO material group K) and aluminum and non-ferrous materials (ISO material group N) where high wear resistance and surface finish are priorities. The VCGT geometry with positive side clearance and a neutral hand orientation makes it adaptable to a range of external turning and boring operations in production and job-shop environments. The screw-holding method ensures secure seating in compatible VCGT toolholders.

Key Features

• VCGT333 / VCGT160412 insert geometry with 35-degree included angle for low cutting forces
• Polished carbide grade ACN15K with LMF+ chip breaker for cast iron and non-ferrous applications
• 1.20 mm corner radius for improved surface finish on finishing passes
• Positive side clearance reduces cutting friction and heat generation
• Neutral hand orientation for flexible toolholder compatibility
• Screw-mount holding method for rigid, repeatable insert indexing

Compatibility

Designed as an OEM-style replacement turning insert for use in VCGT-style screw-clamp toolholders compatible with the VCGT333 ANSI insert geometry and VCGT160412 ISO insert geometry.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's recommended specification. Inspect the insert pocket and seating surface for chips or debris before seating a new insert to ensure accurate positioning and prevent premature edge failure.
