Kennametal 1162190 Turning Insert 3/8 Inch Ic Carbide

Product Description

The KENNAMETAL 1162190 is a solid carbide turning insert designed for precision metal removal in CNC and manual turning applications. Built to the CCMT32.51LF geometry with a K313 grade designation, this uncoated insert features an 80-degree diamond shape and a positive rake angle of 5 degrees for efficient chip formation. The LF chip breaker geometry and honed cutting edge make it well suited for light-to-medium finishing passes. With a 3/8-inch inscribed circle and a corner radius of 1/64 inch, this insert is sized for standard CCMT toolholders. Licensed machinists and CNC operators working in production turning environments will find this a reliable uncoated carbide option for non-ferrous and superalloy workpiece materials.

This insert is intended for turning, facing, and boring operations on non-ferrous metals, superalloys, and titanium. The uncoated K313 carbide grade corresponds to material grades C3 and C4, making it appropriate for applications where coating buildup on the cutting edge would be detrimental, such as finishing cuts on aluminum or titanium alloys. The neutral hand orientation allows use in standard CCMT screw-on toolholders without handedness restrictions. This insert is sold individually, with a minimum order quantity of 5 units.

Key Features

• 80-degree diamond insert shape (CCMT style) with positive rake for efficient chip evacuation
• LF chip breaker geometry optimized for light finishing and semi-finishing cuts
• Uncoated K313 solid carbide grade suited for non-ferrous metals, superalloys, and titanium
• Honed cutting edge style for improved edge integrity on finish passes
• Screw-on insert holding method for secure, repeatable seating in compatible toolholders
• Two cutting edges per insert for extended tool life between changeovers

Compatibility

Designed as a screw-on replacement insert for standard CCMT32.51 toolholders accepting an 80-degree diamond insert with a 3/8-inch inscribed circle. Conforms to ANSI and ISO standards for CCMT insert geometry. Industry standard number: CCMT3251LF.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Power down and lock out the machine spindle before indexing or replacing the insert. Use the manufacturer-recommended torx or hex key to seat the clamping screw; do not overtighten, as this can fracture the carbide insert body. Verify the insert is fully seated in the pocket before resuming operation.
