Iscar 6450087 Grooving Insert TGMF508F IC908 Top-grip

Product Description

The ISCAR 6450087 is a solid carbide grooving insert carrying the TGMF508F grade designation and IC908 manufacturer grade, designed for precision grooving and parting operations on CNC lathes and turning centers. The insert delivers a 5 mm cutting width and a maximum depth of cut of 3 mm, making it well suited for shallow to medium-depth groove profiles. The TiAlN coating applied via PVD process provides thermal resistance and edge hardness, extending tool life across a broad range of workpiece materials. This is a double-ended insert, allowing two usable cutting edges per unit. Installation and tooling selection are handled by machinists and CNC turning specialists.

The TGMF508F IC908 insert belongs to the ISCAR Top-Grip series and is intended for universal application across multiple material groups, including steel, stainless steel, cast iron, high-temperature alloys, and non-ferrous materials. The F chip breaker geometry supports chip control in general-purpose grooving scenarios. With a 0.80 mm corner radius and an overall length of 17.80 mm, this insert fits standard Top-Grip toolholders configured for the 508 insert size. It is appropriate for both production and job-shop turning environments.

Installation Notes

This insert is installed and replaced by qualified machinists or CNC tooling technicians. Before changing inserts, ensure the machine spindle is fully stopped and the turret or toolholder is de-energized per shop lockout/tagout procedures. Use the appropriate torque wrench and insert clamping screws specified for the Top-Grip toolholder to secure the insert without over-tightening. Inspect the seating pocket for chips or debris before seating the new insert to ensure proper contact and runout.
