Iscar 6450083 Grooving Insert TGMF304F IC908 3mm Top-grip

Product Description

The ISCAR 6450083 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. It carries the TGMF304F geometry and IC908 grade, featuring a PVD-applied TiAlN coating that supports cutting across a broad range of workpiece materials. The insert delivers a 3.00 mm cutting width with a maximum depth of cut of 1.80 mm and a corner radius of 0.40 mm. Its neutral hand orientation suits standard radial grooving setups. Machinists and CNC turning technicians working in production or job-shop environments install this insert into compatible Top-Grip toolholders.

This insert is suited for universal application across multiple workpiece material groups, including steels, stainless steels, cast irons, non-ferrous alloys, and high-temperature alloys as indicated by material grade codes C1, C2, C6, and C7 and ISO workpiece material codes H, K, M, P, and S. It fits within the Top-Grip series clamping system, which is commonly used in external grooving and face grooving operations on medium-duty turning equipment in both residential-shop and industrial production settings.

Key Features

• IC908 carbide grade with PVD TiAlN coating for broad material compatibility and extended tool life
• 3.00 mm cutting width with a maximum depth of cut of 1.80 mm
• 0.40 mm corner radius and F chip breaker geometry for controlled chip formation
• Neutral hand orientation fits standard radial grooving setups without a handed toolholder requirement
• Conforms to ISO 13399 tooling data standards for use with modern CAM and tool management systems
• TGMF insert style for use in Top-Grip series clamping toolholders

Compatibility

Designed as an OEM-style replacement or direct-use insert for ISCAR Top-Grip series toolholders accepting the TGMF304 insert style. Compatible with workpiece material groups designated H, K, M, P, and S per ISO material classification.

Installation Notes

Installation is performed by a qualified CNC machinist or tooling technician. The machine spindle must be stopped and the turret fully indexed to a safe position before insert replacement. Use the appropriate torx or clamping key specified for the Top-Grip toolholder to secure the insert without overtightening. Verify insert seating and clamping before resuming cutting operations.
