Kennametal 7093348 Dcgt Turning Insert 55 Degree Carbide

Product Description

The KENNAMETAL 7093348 is a DCGT-style carbide turning insert designed for precision metal cutting operations on CNC and manual lathes. The insert features a diamond shape with a 55-degree included angle and a 7-degree relief angle, providing a sharp, clearance-positive geometry suited for finishing passes and light interrupted cuts. The KCU10B grade substrate is coated with AlTiN (aluminum titanium nitride) for improved wear resistance and thermal stability at elevated cutting speeds. With two usable cutting edges and a neutral hand orientation, this insert fits a wide range of DCGT-compatible toolholders. Licensed machinists and CNC operators in job shops, aerospace, and general machining environments are the primary installers.

This insert is used in turning applications on ferrous and non-ferrous workpiece materials where close tolerances and fine surface finishes are required. The HP chip breaker geometry controls chip evacuation during light finishing cuts, reducing built-up edge and improving part quality. It is suited for internal and external turning operations on CNC turning centers and manual engine lathes equipped with DCGT insert pockets. The 3/8-inch inscribed circle and 5/32-inch thickness dimension make it compatible with standard DCGT 3252 pocket toolholders.

Key Features

• DCGT insert style with 55-degree included angle for positive cutting geometry
• KCU10B carbide grade with AlTiN coating for wear and heat resistance at high speeds
• 7-degree relief angle (clearance code C) supports finishing and light-cut applications
• HP chip breaker promotes efficient chip control during light finishing passes
• Two cutting edges per insert for extended usable tool life
• Neutral hand orientation fits both right-hand and left-hand DCGT toolholders

Compatibility

Designed as an OEM-style replacement for DCGT 3252 insert pockets. Compatible with standard DCGT-style turning toolholders accepting a 3/8-inch inscribed circle insert with a 5/32-inch thickness (insert size code 3252).

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and zero-energy-lock the machine before indexing or replacing inserts. Use a torx or hex key of the correct size specified by the toolholder manufacturer to secure the insert clamp or screw - do not overtighten. Inspect the insert pocket for chips or wear before seating the new insert to ensure proper seating and cutting-edge registration.
