Kennametal 7093780 Ccgt Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7093780 is a CCGT-style carbide turning insert designed for precision external turning operations on CNC and manual lathes. Manufactured in a diamond (rhombic) shape with an 80-degree included angle and a 7-degree relief angle, this insert provides a sharp, defined cutting edge suited for finishing cuts on ferrous and non-ferrous materials. The KCU10B grade substrate is coated with AlTiN (aluminum titanium nitride) for improved heat resistance and wear life at elevated cutting speeds. The LF chip breaker geometry promotes controlled chip evacuation during light finishing passes. Licensed HVAC and machining trade professionals specify this insert for tight-tolerance surface finish work.

This insert is a neutral-hand CCGT geometry suitable for both OD turning and facing operations where a positive rake angle and fine corner radius are required. The 0.0156-inch (1/64 inch) corner radius makes it appropriate for finishing passes requiring minimal surface roughness on components such as shafts, bores, and flanged parts. It seats in CCGT-compatible toolholders with a C-clearance, G-tolerance designation. Each insert provides two cutting edges, allowing the insert to be indexed before replacement.

Key Features

• CCGT insert style with 80-degree diamond shape and 7-degree relief angle for positive cutting geometry
• KCU10B carbide grade with AlTiN coating for extended tool life at high cutting speeds
• LF chip breaker optimized for light finishing cuts and controlled chip flow
• 0.0156-inch (1/64 inch) corner radius for fine surface finish applications
• Neutral hand orientation compatible with standard CCGT toolholders
• Two indexable cutting edges per insert

Compatibility

Designed as a direct-fit replacement for CCGT-style insert seats with C-clearance and G-tolerance specifications in standard CCGT-compatible turning toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and in an e-stop or locked-out state before changing inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer — do not over-tighten the clamping screw, as this can fracture the carbide substrate. Verify insert seating and shim condition before resuming cutting operations. Inspect the insert pocket for debris or damage that could affect insert indexing accuracy.
