Widia 6686432 Wgc Grooving Insert 0.125 in Carbide

Product Description

The WIDIA 6686432 is a carbide grooving insert in the WGC series, designed for single-edge grooving operations on CNC lathes and turning centers. It carries a manufacturer grade of WU25PT with a PVD-applied TiAlN coating, optimizing wear resistance and edge retention at elevated cutting temperatures. The insert features a neutral hand orientation, a positive rake geometry, and a clamp-style holding method. Cutting width is 0.125 inches (3.18 mm) and maximum depth of cut is 0.0882 inches (2.24 mm). The PT chip breaker geometry supports controlled chip evacuation in demanding applications.

This insert is primarily rated for superalloys and titanium (ISO material group S), with secondary suitability for steel, stainless steel, non-ferrous metals, and cast iron (ISO groups P, M, K, and N). It is intended for use by machinists and tooling specialists performing precision grooving, parting, and recessing operations in production or job-shop environments. The size 3 insert fits WGC-compatible toolholders and is sold individually with a minimum order quantity of 5 units.

Key Features

• Carbide substrate with PVD TiAlN coating for extended tool life in high-temperature cuts
• WU25PT manufacturer grade optimized for superalloys and titanium
• 0.125 inch (3.18 mm) fixed cutting width with no full radius
• Positive rake and 10-degree relief angle reduce cutting forces
• PT chip breaker promotes chip control in tough workpiece materials
• Single cutting edge; neutral hand for flexible toolholder mounting

Compatibility

Designed for use in WGC-series compatible clamp-style toolholders accepting size 3 grooving inserts. ANSI and ISO designation WG125I03P05PT can be used to cross-reference compatible holders and alternative sources.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the toolholder is properly seated and torqued per the toolholder manufacturer's specifications before indexing or replacing inserts. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Do not exceed the maximum depth of cut rating for this insert geometry.
