Kennametal 7093516 Vnmg Turning Insert Diamond Carbide

Product Description

The KENNAMETAL 7093516 is a VNMG-style indexable carbide turning insert designed for precision metal-cutting operations on CNC lathes and manual turning centers. It features a diamond-shaped insert body (35-degree included angle) with a 0.40 mm (0.0157 inch) corner radius and an AlTiN coating applied over a KCU10B carbide grade substrate. The neutral hand orientation and MP chip breaker geometry make it well suited for finishing and semi-finishing passes where controlled chip evacuation and surface finish consistency are priorities. At 0.03 pounds per insert, it is lightweight and easy to index in standard VNMG toolholders.

This insert is intended for turning operations on a wide range of workpiece materials where the AlTiN coating provides thermal resistance and extended tool life. It fits residential and commercial machine shop environments as well as production turning cells. Licensed machinists and CNC programmers working with ferrous and non-ferrous alloys, hardened steels, or cast iron will find the KCU10B grade and MP chip breaker combination appropriate for moderate to high cutting speeds. The four available cutting edges per insert reduce tooling cost per part and support lean tooling inventory programs.

Key Features

• VNMG insert style with 35-degree diamond shape (V code) for tight-clearance profiling and finishing cuts
• AlTiN coating over KCU10B carbide grade for thermal stability and wear resistance at elevated cutting speeds
• 0.40 mm corner radius (1/64 inch) delivers fine surface finish in light finishing applications
• MP chip breaker geometry promotes controlled chip breaking across a range of feed rates and depths of cut
• Neutral hand orientation compatible with both left- and right-hand VNMG toolholder setups
• Four indexable cutting edges per insert maximize value per unit

Compatibility

Designed as an OEM-style replacement insert for standard VNMG toolholders accepting a size 331 insert with N clearance, M tolerance, and a 3/16 inch (0.1875 inch) insert thickness and width.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist with the machine spindle fully stopped and the toolholder secured in a vise or turret. Use the appropriate torx or hex key specified by the toolholder manufacturer to seat the insert clamp — do not overtighten. Confirm insert seating and edge condition visually before resuming cutting operations. Dispose of spent carbide inserts in accordance with local regulations for industrial cutting tool waste.
