Walter 6118734 Grooving Insert 0.187 in Tiger-tec WSM33S

Product Description

The WALTER 6118734 is a solid carbide grooving insert designed for precision groove turning and parting operations on CNC lathes and turning centers. It carries the Tiger-tec series designation and features a multilayer PVD coating combining Al2O3, TiAlN, and ZrCN for high-temperature resistance and extended tool life. The insert delivers a cutting width of 0.187 inches (4.75 mm) and a maximum depth of cut of 0.118 inches (3.00 mm). The UF4 chip breaker geometry is optimized for controlled chip formation in demanding materials. This insert is installed by machinists and CNC tooling technicians working in production and job-shop environments.

This grooving insert is engineered primarily for machining superalloys, with material grade compatibility covering S30, M30, and P35 workpiece classifications. It suits applications in aerospace, energy, and medical manufacturing where tight tolerances and difficult-to-machine alloys are common. The neutral hand orientation and GX insert style make it compatible with matching WALTER toolholders using a clamp-style holding method. The UF4 chip breaker supports stable cutting in both roughing and finishing groove passes within the rated depth range of 0.100 to 0.150 inches (3.00 to 4.00 mm).

Key Features

• Solid carbide construction with PVD-applied Al2O3, TiAlN, and ZrCN multilayer coating for heat and wear resistance
• Cutting width of 0.187 inches (4.75 mm) with a corner radius of 0.016 inches (0.40 mm)
• Maximum depth of cut of 0.118 inches (3.00 mm); rated depth range 0.100 to 0.150 inches
• UF4 chip breaker geometry for positive chip control in superalloys and stainless materials
• Neutral hand insert suitable for both OD grooving and parting setups
• Compliant with ANSI and ISO insert standards; ANSI Code GX243E475N04UF4 WSM33S, ISO Code GX24-3E475N04-UF4

Compatibility

Designed for use in GX-style clamp-type toolholders accepting 3E475N04 insert size. Primary workpiece material codes are M, P, and S, covering stainless steels, carbon and alloy steels, and superalloys. Manufacturer grade WSM33S corresponds to material grades S30, M30, and P35.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing the insert. Confirm the clamp and toolholder pocket are clean and free of chips before securing the insert. Verify depth-of-cut and feed parameters remain within the rated range for the target workpiece material to avoid premature edge failure.
