Kennametal 7096381 Cdhh Boring Insert Carbide KCU10B

Product Description

The KENNAMETAL 7096381 is a carbide boring insert designed for internal turning and boring operations on CNC lathes and machining centers. It features an 80-degree diamond insert shape (CDHH style) with a 15-degree relief angle and an AlTiN coating for extended tool life in demanding cutting applications. The insert is left-hand oriented and carries Kennametal grade KCU10B, a carbide grade suited for interrupted cuts and tough workpiece materials. Licensed machinists and CNC operators install this insert as a replacement cutting edge in compatible boring bar toolholders.

This insert is used in precision boring applications in both job shop and production environments. The CDHH style with size code 120605 fits toolholders configured for left-hand boring in tight-bore or back-boring scenarios. With four cutting edges per insert, it offers multiple indexes before replacement, supporting cost-effective use in high-volume turning operations. It is appropriate for shops running ferrous and non-ferrous materials where AlTiN coating provides heat resistance and reduced built-up edge.

Key Features

• 80-degree diamond insert shape with 15-degree relief angle for clearance in bore profiles
• AlTiN coating provides thermal resistance and extended cutting edge life
• Four cutting edges per insert for maximum indexing value
• Left-hand cut orientation for dedicated left-hand boring bar toolholders
• Corner radius of 0.007 inches (0.18 mm) for fine surface finish in small-bore work
• Chipbreaker style H suited for chip control in continuous and semi-interrupted cuts

Compatibility

Designed as an OEM-style replacement boring insert for left-hand CDHH-style toolholders accepting size code 120605 inserts. Confirm toolholder pocket geometry and insert seat dimensions before ordering.

Installation Notes

CNC machinists and toolroom technicians install boring inserts. Power down and lock out the machine spindle before indexing or replacing inserts. Use a torque wrench appropriate for the clamping screw specification listed in the toolholder manual — do not overtighten, as carbide inserts are brittle and can crack under excess clamping force. Inspect the insert pocket and clamping seat for chips or debris before seating the new insert.
