Kennametal 7096409 Cdhb Carbide Boring Insert KCU10B

Product Description

The KENNAMETAL 7096409 is a CDHB-style carbide boring insert designed for precision internal turning and boring operations on CNC and manual lathes. Manufactured to grade KCU10B with an AlTiN coating, this insert delivers thermal resistance and wear performance in demanding ferrous and non-ferrous boring applications. The diamond insert shape provides an 80-degree included angle and 15-degree relief angle, giving the cutting edge both strength and clearance. Two cutting edges per insert extend usable tool life. The 0.0070-inch corner radius produces tight-tolerance surface finishes in fine boring passes. This insert is installed and replaced by machinists and CNC tooling technicians in production and job-shop environments.

This insert is suited for fine boring and internal diameter finishing operations where tight dimensional control is required. The neutral hand orientation makes it adaptable to both right-hand and left-hand boring bar configurations depending on toolholder setup. The KCU10B grade with AlTiN finish performs in interrupted cuts and light-to-moderate feed applications on steel and hard materials. Typical use cases include finish boring of bearing bores, housing bores, and precision cylindrical features in medium-volume production.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or removing the insert. Use the correct torque wrench and insert screw to avoid clamp distortion. Inspect the insert pocket and seating surface for chips or debris before installation to ensure accurate seating and repeatable tool offset.
