Sandvik Coromant 7080746 Turning Insert VBMT21.51-UF 4335

Product Description

The SANDVIK COROMANT 7080746 is a carbide turning insert in the VBMT style, designed for precision metal turning operations on CNC and manual lathes. This insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous and interrupted cuts. It features a 35-degree diamond shape (Insert Shape Code V), a neutral hand orientation, and a UF chip breaker geometry suited for light finishing passes. With 2 cutting edges and a corner radius of 0.0156 inches (1/64 inch), it delivers consistent surface finish on steel workpieces. The insert is held in place by a screw-clamp method and is sized to the CoroTurn 107 series standard.

This insert is intended for steel turning applications, classified under ISO workpiece material code P. It fits within the CoroTurn 107 series tooling system and is appropriate for finishing and semi-finishing operations where tight tolerances and surface quality are priorities. The UF chip breaker geometry is optimized for low cutting forces and controlled chip formation at light depths of cut. Licensed machinists, CNC programmers, and tool and die professionals typically specify this insert for production turning on steel components.

Key Features

Compatibility

Designed as an OEM-specification insert for SANDVIK COROMANT CoroTurn 107 series toolholders accepting VBMT-style inserts with screw-clamp retention.

Installation Notes

Installation should be performed by qualified machinists or tooling technicians. Always index or replace the insert with the machine powered down and the spindle fully stopped. Use the correct Torx or hex key to the toolholder manufacturer's specified seating procedure when securing the clamping screw. Do not mix insert grades or chip breaker styles within the same toolholder setup without verifying cutting parameter compatibility.
