Walter 7318883 Grooving Insert 0.118 in Neutral Carbide

Product Description

The WALTER 7318883 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Manufactured to GX34 insert style standards, it carries the WSM33S grade designation with an aluminum finish applied via PVD coating process. The CE4 chip breaker geometry and 10-degree rake angle are engineered to handle demanding cuts in superalloys and similar difficult-to-machine materials. The neutral hand orientation suits standard radial grooving setups. This insert is installed by machinists and CNC tooling specialists in production and job-shop turning applications.

The 7318883 fits GX34-series toolholders and is primarily intended for grooving superalloys, as well as steel and stainless workpiece materials covered under the P, M, and S material codes. With a cutting width of 0.118 inches and a corner radius of 0.012 inches, it suits groove profiles requiring close dimensional control. The Tiger-tec Silver series designation indicates Walter's PVD-coated carbide line aimed at extended tool life in high-temperature alloy cutting. Typical applications include external grooving, undercut profiles, and parting-off operations on turned components in aerospace, oil and gas, and general precision manufacturing.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing the insert. Ensure the insert pocket and clamping surfaces are clean and free of chips before seating the insert to maintain accurate cutting geometry. Follow the toolholder manufacturer's clamping torque specifications and do not mix insert grades within the same toolholder setup without verifying compatibility.
