Ingersoll Cutting Tools 5700670 Ceramic Turning Insert Tnga 432

Product Description

The INGERSOLL CUTTING TOOLS 5700670 is a TNGA-style ceramic turning insert designed for single-point turning operations on CNC and manual lathes. It carries the AB30 manufacturer grade with a multilayer Al2O3 and TiCN PVD coating, delivering thermal and abrasion resistance suited to interrupted and continuous cuts. The insert features a triangular shape with a 60-degree included angle, six cutting edges, a 0.031-inch corner radius, and a 0.500-inch inscribed circle. At 0.187 inches thick and 0.866 inches in cutting length, it is clamped in place using a standard top-clamp toolholder. Licensed machinists and CNC operators are the primary installers.

This insert is intended for turning cast iron and hardened steel workpieces, corresponding to ISO primary workpiece material codes H and K. It is a negative-rake geometry insert with a neutral hand designation and an A-style chip breaker, making it suitable for finishing and semi-finishing passes where consistent chip control and edge integrity are critical. The TNGA 432 insert size code and ISO code TNGA220408 AB30 allow direct cross-reference for toolholder seat compatibility. It is sold individually with a minimum order quantity of 10 units.

Installation Notes

Insert installation and indexing should be performed by qualified machinists with the machine powered down and in a locked-out state per applicable machine safety procedures. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when seating the insert. Inspect the toolholder seat and clamp for wear or damage before installing a fresh insert edge. Handle ceramic inserts carefully to avoid chipping the cutting edge prior to use.
