Suited for radial grooving and groove turning in the automotive and general metalworking industries, the Walter Cut UD4 insert geometry is designed for maximum process reliability, optimum chip formation, high productivity and reduced tooling costs.

It features a multifunctional chip breaker design for greater chip control, thanks in part to a double geometry that delivers a large application area. The insert also offers a strong, zero-degree primary chamfer that strengthens the cutting edge; a silver surface that makes for easy wear detection; and full use of cutting edges.

According to the company, a standard PVD coating typically produces a high rate of heat transfer into the cutting tool insert substrate, which leads to higher wear rates. The UD4’s Tiger·tec silver PVD aluminum oxide coating is designed to produce less heat in the substrate, leading to longer tool life, reduced tool and tool-change costs, increased process reliability, and increased productivity.

The main application area for the UD4 is grooving and groove turning on forged materials such as transmission components, gears and shafts. It is said to work especially well in low-carbon steels where chip control is a particularly big challenge. Targeted workpiece materials are steel and cast iron.
