Kennametal 4175855 Grooving Insert KCU10 Solid Carbide Altin

Product Description

The KENNAMETAL 4175855 is a solid carbide grooving insert in the Top Notch series, designed for precision external grooving and turning operations on CNC lathes and turning centers. Manufactured to grade KCU10 with a PVD-applied AlTiN coating, this insert delivers wear resistance and thermal stability at elevated cutting speeds. The right-hand insert carries a 1.58 mm cutting width and a maximum depth of cut of 2.79 mm, making it well suited for shallow-to-medium groove profiles in steel, stainless, and similar workpiece materials. It is installed by machinists and CNC operators using a clamp-style holding method compatible with Top Notch toolholders.

This insert is intended for use in production turning environments where consistent groove geometry and surface finish are required. The NG insert style with a 55-degree included angle and a 0.19 mm corner radius suits applications demanding controlled chip flow via the K chip breaker geometry. Typical use cases include groove turning on shafts, hydraulic components, and precision-machined parts in job shop and high-volume production settings. The metric measurement standard and 2062 insert size align with metric-configured Top Notch tooling setups.

Key Features

Compatibility

Designed for use with Top Notch series clamp-style grooving toolholders. The manufacturer cross-reference number for this insert is NG2062R/LK. Verify toolholder compatibility with KENNAMETAL Top Notch system specifications before installation.

Installation Notes

Installation is performed by qualified machinists or CNC operators with the machine spindle fully stopped and all energy sources locked out per OSHA lockout/tagout procedures. Seat the insert fully against the toolholder pocket before tightening the clamp; uneven seating can cause premature edge failure or dimensional error. Inspect the insert pocket and clamp for debris or wear before each insert change. Do not exceed the recommended depth-of-cut range for this insert size.
