Kennametal 1817588 Grooving Insert KC5025 Solid Carbide

Product Description

The KENNAMETAL 1817588 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and parting operations on CNC turning centers and lathes. It carries a TiAlN coating applied via PVD process, which provides thermal resistance and wear protection at elevated cutting speeds. The insert is left-hand oriented with a 3.18 mm (0.1252 inch) cutting width and a maximum depth of cut of 6.35 mm (0.2500 inch). The KC5025 grade combines a tough carbide substrate with the PVD TiAlN finish, making it well suited for interrupted cuts and general-purpose steel and cast iron applications.

This insert is intended for use in Top Notch series grooving toolholders on manual or CNC lathes in production and job-shop environments. Typical applications include external groove turning, plunge grooving, and light parting work on ferrous and non-ferrous materials. The positive rake angle of 10 degrees and the K chip breaker geometry promote efficient chip control and reduced cutting forces in moderate-to-finish depth grooves. Licensed machinists and CNC operators are the primary installers of this insert style.

Key Features

• Solid carbide construction with PVD TiAlN coating for extended tool life in abrasive cuts
• Left-hand insert orientation for right-to-left grooving direction
• 3.18 mm cutting width with a maximum depth of cut of 6.35 mm
• Positive 10-degree rake angle with K chip breaker for controlled chip evacuation
• 0.19 mm (0.0075 inch) corner radius for semi-finish groove profiles
• Top Notch series toolholder compatibility for secure, repeatable seating

Compatibility

Designed for use with Top Notch series grooving toolholders that accept the NFD-style insert geometry with a size designation of 3125.

Installation Notes

Insert installation should be performed by a qualified machinist or CNC operator with the machine fully stopped and in a safe, locked-out state. Use the appropriate Top Notch clamping screw and torque key as specified for the toolholder — do not over-tighten by hand. Inspect the toolholder pocket for chips or debris before seating the insert to ensure proper contact and accurate depth positioning. Replace the insert at the first sign of chipping, built-up edge, or surface finish degradation to avoid workpiece damage or toolholder wear.
