Kennametal 1163316 NPL52 K68 Carbide Profiling Insert

Product Description

The KENNAMETAL 1163316 is a solid carbide profiling and turning insert in the Top Notch series, designed for precision material removal on non-ferrous metals, superalloys, and titanium. It features a parallelogram shape with an NPL52 insert style and K68 fine-grain carbide grade. The insert is uncoated with a WC-Co finish, runs with a negative rake angle, and delivers a 0-degree relief angle. Four cutting edges extend usable tool life between index cycles. This insert is installed by machinists and CNC turning technicians in production and job-shop environments.

This insert is suited for profiling and turning operations on non-ferrous metals, superalloys, and titanium workpieces. The left-hand configuration makes it appropriate for specific tool holder orientations on CNC lathes and manual turning centers. The 55-degree included angle and 0.0312-inch corner radius support contour-following passes and finishing cuts where consistent edge geometry is critical. The screw-holding method provides secure clamping with straightforward indexing.

Key Features

• NPL52 insert style, K68 fine-grain carbide grade — uncoated WC-Co for non-ferrous and superalloy applications
• Four cutting edges per insert for extended tool life between replacements
• 0.0312-inch (0.79 mm) corner radius for controlled profiling and finish turning
• Maximum depth of cut of 0.1257 inches supports moderate material removal in contour passes
• Parallelogram shape with 55-degree included angle for profile-following geometry
• Screw clamping method for positive, repeatable insert location

Compatibility

Designed for use in Top Notch series screw-clamp toolholders accepting NPL52-style inserts. ISO code KCGX110308L15 and standards NPL52 and KCGX110308L15 apply. Verify toolholder pocket geometry and hand orientation before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the turret is locked out before indexing or replacing inserts. Use the correct torque driver for the clamping screw to avoid seat damage — do not overtighten by hand. Confirm left-hand orientation matches the toolholder pocket before seating the insert.
