Widia 4118585 Grooving Insert Wmt 0.1248 Inch Carbide

Product Description

The WIDIA 4118585 is a carbide grooving insert in the WMT series, designed for precision grooving operations on CNC lathes and turning centers. It features a 0.1248-inch cutting width and a maximum depth of cut of 1.0000 inch, making it suited for consistent, repeatable groove profiles. The insert carries a PVD-applied TiAlN coating and manufacturer grade WU10PT, which supports extended tool life in demanding cutting environments. With a positive rake angle and a 5-degree relief angle, this insert reduces cutting forces and helps maintain surface finish. Licensed machinists and CNC operators working in production turning applications will find this a direct-fit replacement insert.

This insert is intended for grooving superalloys and titanium as its primary workpiece material, with secondary capability across hard materials, steel, stainless steel, non-ferrous metals, and cast iron. The neutral hand orientation makes it compatible with standard grooving toolholders accepting WMT-series inserts. Insert size code 3 with a 1/8-inch cutting width and a full-radius designation of No, combined with a 0.0091-inch corner radius, suits applications where groove geometry and wall definition are critical. Chip control is managed by the PT chip breaker geometry built into the insert face.

Key Features

• WMT series insert with size code 3 and 0.1248-inch cutting width for precise groove profiles
• PVD TiAlN coating (grade WU10PT) for heat resistance and extended tool life
• Positive rake angle with 5-degree relief reduces cutting forces on difficult materials
• PT chip breaker geometry promotes chip control during grooving passes
• Two cutting edges per insert for added value in production runs
• Rated for superalloys and titanium as primary material, with broad secondary material compatibility

Compatibility

Designed for use with WMT-series grooving toolholders accepting size 3 inserts. ANSI and ISO code WMTS125I3P03PT. Consult the toolholder manufacturer specifications to confirm seat geometry before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine before changing inserts. Ensure the insert pocket and clamp surfaces are clean and free of chips before seating the new insert. Do not exceed the toolholder manufacturer rated depth of cut or feed rate for this insert size.
