Walter presents double-serrated GD grooving system

The system, consisting of toolholder and two-edged indexable inserts, is characterized by a patented double-serration profile. This ensures a uniquely stable, positive-locking connection between the tool body and indexable insert. This reliably absorbs lateral forces and prevents the cutting insert from being pushed out to the side. This is particularly beneficial when groove turning, widening grooves, chamfering, copy turning and parting off. The precision-fit serration between the cutting insert and toolholder not only provides maximum stability and minimizes wear, it also achieves longer cutting insert tool life and extends the service life of the tool support by up to 50%.

As field tests at customers showed, the Groov·tec™ GD grooving system can be used with higher cutting parameters due to the innovative serration profile and the optional precision cooling. This in turn increases the throughput and productivity. Walter offers Groov·tec™ GD in shank sizes from 16 to 25 mm (5/8 to 1") with insert widths from 2.5 to 6.0 mm – for flexible use in a wide application range. Another special feature is the new Tiger·tec^® Gold indexable inserts developed specifically for grooving in four PVD and three CVD grades. They also play a part in making the system suitable for universal application in steel, stainless steels, difficult-to-cut materials and cast iron materials. This makes the grooving system ideal for applications where high process reliability and precision are required – for example in highly automated production or large batch production. And that's not all – users can benefit from 30 to 150% longer tool life than standard systems with prismatic clamping.
