Kennametal 7093839 Ccmt Turning Insert Carbide Altin

Product Description

The KENNAMETAL 7093839 is a CCMT-style carbide turning insert designed for precision external turning operations on CNC and manual lathes. Built to grade KCU10B with an AlTiN coating, this insert delivers thermal resistance and edge durability across a range of workpiece materials. It features a diamond insert shape with an 80-degree included angle, a 7-degree relief angle, and a 0.008 inch (0.20 mm) corner radius for moderate-radius finishing and semi-finishing passes. The LF chip breaker geometry promotes reliable chip control in light-to-medium feed applications. Neutral hand orientation allows use in standard right-hand toolholders. Licensed machinists and CNC operators typically specify and install this insert.

This insert is suited for external turning on small-to-medium diameter workpieces where tight tolerances and consistent surface finish are required. The CCMT designation and 5/32 inch insert thickness make it compatible with standard CCMT toolholder pockets commonly found in production turning cells and job shops. The AlTiN coating extends tool life in dry or near-dry machining conditions, particularly when cutting alloy steels, stainless steels, and cast irons at moderate cutting speeds. This insert is sold individually, with a minimum order quantity of 5 pieces.

Key Features

• CCMT insert style with diamond shape (80-degree included angle) for versatile external turning
• KCU10B carbide grade with AlTiN coating for thermal resistance and extended tool life
• 0.008 inch (0.20 mm) corner radius suitable for semi-finishing and moderate-radius contour turning
• LF chip breaker geometry for controlled chip evacuation in light-to-medium feed ranges
• 7-degree relief angle (clearance code C) reduces flank wear in standard turning applications
• Neutral hand insert fits standard right-hand CCMT toolholder pockets without modification

Compatibility

Designed as an OEM-style replacement insert for standard CCMT toolholder pockets accepting a 5/32 inch thick, size code 32505 diamond-shaped insert.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the lathe spindle before seating or replacing inserts. Use the correct torx or clamp-style wrench specified for the toolholder to secure the insert without overtightening. Inspect the toolholder pocket for debris or damage before seating a new insert to ensure proper contact and repeatable tool height.
