Kennametal 7093873 Dpgt Diamond Turning Insert Carbide

Product Description

The KENNAMETAL 7093873 is a DPGT-style carbide turning insert designed for precision external turning operations on CNC and manual lathes. This insert features a diamond shape with a 55-degree included angle, a 0.0157-inch (0.40 mm) corner radius, and an 11-degree relief angle. The KCU10B grade substrate is coated with AlTiN (aluminum titanium nitride), providing thermal resistance and wear performance in demanding cutting applications. With four usable cutting edges and a neutral hand orientation, this insert delivers consistent material removal rates in both roughing and finishing passes.

This insert is suited for turning operations on steel, stainless steel, and similar ferrous materials in light to moderate chip-load applications. The LF chip breaker geometry is optimized for finishing cuts requiring tight tolerances and smooth surface finishes. It is typically used by CNC machinists and lathe operators in production and job-shop environments where tool life consistency and edge repeatability are critical. The 5/32-inch thickness and DPGT designation make it compatible with standard DPGT toolholders requiring this insert geometry.

Key Features

• Diamond insert shape with 55-degree included angle for access in tight-profiling cuts
• AlTiN coating on KCU10B carbide grade for elevated thermal and wear resistance
• Four cutting edges per insert, reducing cost per edge in production runs
• LF chip breaker geometry optimized for finishing and light turning applications
• 0.0157-inch (0.40 mm) corner radius for controlled surface finish
• Neutral hand orientation for flexible toolholder compatibility

Compatibility

Designed as a direct-fit replacement for standard DPGT-style toolholders accepting a 5/32-inch thick diamond insert with a 0.40 mm corner radius and DPGT geometry designation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before seating or indexing inserts. Ensure the toolholder pocket is clean and free of chips or debris before installing the insert. Follow the toolholder manufacturer's specified clamping torque and seating procedure to prevent insert movement during cutting.
