Kennametal 1163216 NPL505 KC730 Carbide Profiling Insert

Product Description

The KENNAMETAL 1163216 is a solid carbide profiling and turning insert in the Top Notch series, designed for high-productivity metal removal on steel, stainless steel, superalloys, and titanium. It carries the KC730 manufacturer grade with a PVD-applied TiN coating, providing wear resistance across a range of ISO material groups including P10, P20, M10, M20, S10, and S20. The insert measures 0.375 inches in length, 0.25 inches in inscribed circle diameter, and 0.125 inches thick, with a 0.005-inch corner radius and a parallelogram shape. It features four cutting edges and a negative rake geometry. Installation is performed by licensed machinists and CNC setup technicians as part of a screw-held tooling system.

This insert is suited for profiling and turning operations in production and job-shop environments. Its negative rake and 55-degree included angle make it appropriate for interrupted and continuous cuts on ferrous and exotic alloy workpieces. The left-hand orientation and common chipbreaker configuration support chip control in standard turning center setups. It corresponds to ISO code KCGX110301L15 and meets the NPL505 standard, allowing straightforward identification and cross-referencing in tool management systems.

Key Features

• Solid carbide substrate with KC730 grade and PVD TiN coating for extended tool life on steel and superalloys
• Four cutting edges on a parallelogram-shaped insert maximize value per insert
• 0.005-inch (0.10 mm) corner radius suits fine-to-medium profiling work
• Negative rake geometry with 0-degree relief angle provides edge strength on tough materials
• Screw-held mounting method ensures repeatable seating and quick indexing
• ISO code KCGX110301L15 enables direct cross-reference to standard tooling catalogs

Compatibility

Designed for use in Top Notch series screw-held toolholders accepting NPL505 insert geometry. Compatible with applications targeting ISO material groups P (steel), M (stainless steel), and S (superalloys and titanium). Refer to KENNAMETAL Top Notch toolholder documentation to confirm holder compatibility before installation.

Installation Notes

Insert replacement and indexing should be performed by a qualified machinist or CNC tooling technician with the machine in a fully stopped and locked-out state. Use the manufacturer-specified torque driver for the clamping screw to avoid seat damage or insert fracture — do not overtighten by hand. Inspect the toolholder pocket and seating surface for chips or wear before mounting a new insert. Confirm insert hand orientation (left hand for this part) matches the toolholder before securing.
