Kennametal 1163314 NPL505 K68 Carbide Profiling Insert

Product Description

The KENNAMETAL 1163314 is a solid carbide profiling insert in the Top Notch series, designed for profiling and turning operations on CNC and manual lathes. It features a parallelogram shape with an NPL505 insert style and a K68 fine-grain carbide grade. The insert carries a 55-degree included angle, a 0-degree relief angle, and a negative rake geometry. With four cutting edges and an uncoated WC-Co finish, it delivers consistent edge performance on non-ferrous metals, superalloys, and titanium. A screw-clamped, left-hand configuration keeps the insert securely seated under cutting loads. Licensed machinists and CNC operators in production and job-shop environments are the primary installers.

This insert is suited for profiling and external turning applications where tight tolerances and sharp edge definition are required. The uncoated fine-grain carbide construction performs best on non-ferrous metals (ISO material group N) and superalloys and titanium (ISO material group S). The common chipbreaker geometry accommodates a range of depth-of-cut conditions up to 0.1250 inches. The ISO code KCGX110301L15 provides cross-reference identification for procurement and tooling engineers. It is packaged individually and sold in minimum order quantities of five units.

Key Features

• NPL505 insert style in a parallelogram shape with a 55-degree included angle
• K68 fine-grain solid carbide grade, uncoated WC-Co for non-ferrous and superalloy materials
• Four cutting edges per insert for extended tooling economy
• 0.0050 inch corner radius for controlled edge engagement during profiling passes
• Left-hand, screw-clamped insert holding method for positive, repeatable seating
• Maximum depth of cut of 0.1250 inches supports a wide range of profiling and turning passes

Compatibility

Designed for use in Top Notch series toolholders that accept NPL505 insert style with left-hand orientation. Cross-reference standards NPL505 and KCGX110301L15 apply for toolholder and catalog matching.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician with the machine in a locked-out, zero-energy state. Use the manufacturer-specified screw torque tool for the Top Notch clamping screw to avoid seat damage or insert cracking. Inspect the insert pocket and seating surface for chips or debris before seating a new insert. Verify left-hand orientation matches the toolholder before engaging the clamping screw.
