Iscar 6450043 Grooving Insert TGMF302F IC20 Carbide 3mm

Product Description

The ISCAR 6450043 is a solid carbide grooving insert in the Top-Grip series, manufactured to the TGMF302F geometry with an IC20 uncoated grade. This insert delivers a 3.00 mm (0.1181 inches) cutting width and a maximum depth of cut of 1.80 mm (0.0709 inches), making it suited for precision external grooving and parting operations on CNC turning centers and lathes. The bright, uncoated finish is typical for IC20 carbide, which is intended for general-purpose and finishing cuts. A corner radius of 0.20 mm (0.0079 inches) is built into the insert geometry. Machinists and tooling technicians working in production turning environments install and index this insert type.

The ISCAR 6450043 is designed for use in external grooving toolholders that accept the Top-Grip TGMF insert style in the 302 size. It carries a neutral hand designation, meaning it is suitable for use in both right- and left-hand setups depending on the holder configuration. The IC20 carbide grade and F chip-breaker geometry are intended for universal application across a broad range of workpiece materials, including steel, stainless steel, aluminum, non-ferrous metals, and high-temperature alloys as indicated by ISO material codes H, K, M, N, and S. This insert is a multi-use tool capable of grooving and light parting cuts in a production turning environment.

Installation Notes

Installation is performed by a machinist or tooling technician following the machine tool builder and toolholder manufacturer torque and clamping guidelines for Top-Grip style inserts. Power down and lock out the machine spindle before indexing or replacing the insert. Verify insert seating in the pocket before resuming cuts, and confirm that the holder clamp is fully engaged to prevent insert movement under cutting loads. Dispose of worn inserts in accordance with local regulations for carbide tooling waste.
