Widia 3607236 Nr-k Grooving Insert 0.125 in Carbide

Product Description

The WIDIA 3607236 is a Top Notch grooving insert in the NR-K series, designed for external grooving and turning operations on CNC lathes and turning centers. Built from solid carbide with a PVD-applied TiAlN coating and WIDIA manufacturer grade TN6025, this insert delivers reliable cutting performance on demanding workpiece materials. It features a 0.125 inch (1/8 inch) cutting width, a maximum depth of cut of 0.150 inches, and a full corner radius of 0.0626 inches (approximately 1/16 inch). The positive rake geometry and K-style chip breaker support controlled chip evacuation. Machinists and toolroom technicians install this insert in compatible Top Notch toolholders for grooving, parting, and turning applications.

This insert is suited for machining cast iron, stainless steel, super-alloys and titanium, steel, and non-ferrous metals. It is a right-hand insert intended for use in right-hand Top Notch grooving and turning toolholders. Typical applications include external groove cutting and profiling on production turning equipment in both job shop and high-volume manufacturing environments. The single-end design with two cutting edges provides an economical cutting solution for interrupted and continuous grooving cuts across a range of workpiece diameters.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and verify clamp torque per the toolholder manufacturer's specification. Inspect the insert seat for chips or debris before seating a new insert to ensure proper registration and prevent premature edge failure.
