Kennametal 7093838 Ccmt Turning Insert Carbide Altin

Product Description

The KENNAMETAL 7093838 is a CCMT-style carbide turning insert designed for precision metal cutting on CNC and manual lathes. It features an 80-degree diamond insert shape with a 7-degree relief angle and a 0.80 mm (0.0313 inch) corner radius. The insert is manufactured in the KCU10B grade with an AlTiN (aluminum titanium nitride) coating, which provides heat resistance and wear performance during turning operations. This is a neutral-hand insert with the LF chip breaker geometry, making it suited for light finishing cuts. Machinists, toolroom technicians, and production lathe operators install this type of insert as a direct replacement in compatible CCMT toolholders.

This insert is applicable to external and internal turning operations in production and job-shop environments. The CCMT designation indicates a 80-degree diamond shape, a 7-degree clearance angle, a medium tolerance, and a chip breaker on one side. It is suited for finishing operations on ferrous and non-ferrous materials where tight tolerances and surface finish are priorities. The LF chip breaker geometry is optimized for light finishing passes at lower feed rates and depths of cut. This insert packages individually and must be ordered in multiples of 5.

Key Features

• CCMT insert style with 80-degree diamond shape and 7-degree relief angle
• KCU10B carbide grade with AlTiN coating for wear and heat resistance
• 0.80 mm corner radius for finishing applications
• LF chip breaker geometry designed for light finishing cuts
• Neutral hand orientation - compatible with left or right turning setups depending on toolholder
• 4 cutting edges per insert for extended tool life per unit

Compatibility

Designed as a direct OEM-style replacement for CCMT-style turning toolholders accepting a 1/4-inch inscribed circle carbide insert with a 3/32-inch thickness. Specific toolholder compatibility should be verified against KENNAMETAL CCMT toolholder specifications.

Installation Notes

Insert installation and indexing should be performed with the machine powered down and the spindle locked. Use the appropriate insert torx or hex key to the toolholder manufacturer's specified clamping method - do not overtighten the clamp screw. Inspect the insert seat and clamp for chips or debris before seating the new insert. Worn or damaged inserts should be indexed or replaced before returning the machine to service.
