Widia 3607157 Top Notch Grooving Insert 0.047 in Right Hand

Product Description

The WIDIA 3607157 is a Top Notch style NG grooving insert designed for precision grooving and turning operations on CNC lathes and turning centers. Built from carbide with a TiAlN PVD coating applied through a physical vapor deposition process, this insert delivers wear resistance and thermal stability across demanding cutting applications. It carries a cutting width of 0.0470 inches (1.190 mm) and a maximum depth of cut of 0.0752 inches (1.91 mm). The manufacturer grade is TN6010. With a neutral rake angle and a right-hand orientation, it is suited for machinists and toolroom operators running high-production or precision turning work.

This insert is intended for use in grooving and turning operations across a range of workpiece materials, including steel, cast iron, stainless steel, super-alloys, titanium, and non-ferrous metals. It is sized for insert seat size 3 and fits Top Notch compatible toolholders using a clamp-style holding method. Typical applications include external grooving, profiling, and light turning passes on production lathes. The two cutting edges extend tool life between index cycles, making this insert a practical choice for shops running high-mix or high-volume turning programs.

Installation Notes

This insert is installed and indexed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert firmly against the toolholder pocket surfaces and verify clamp engagement before resuming cuts. Inspect the insert seat and clamping components for chips or debris that could affect seating accuracy.
