Walter’s Cut GX Tiger-tec Silver CVD grooving and parting grades, the WKP13S, WKP23S and WKP33S, are for use on steel and cast-iron applications. These have been introduced in combination with Walter's geometries UD4, UA4, UF4, RD4 along with plunge grooving and parting geometries GD3 and CE4, the company says. This grade and geometry combination is enhanced by developments in a wear-resistant cutting material that boosts cutting parameters while maintaining or improving tool life.

The thicker coating is used with the WKP grades and features aluminum oxide with optimized microstructure for maximum crater wear resistance and enhanced cutting speed due, in part, to reduced friction. A silver flank face permits wear detection and full cutting-edge usage. In addition, a mechanical post-treatment creates compressive stresses that enhance toughness, reducing the chance of chipping on the cutting edge, and boosting load capability and metal removal rates.

According to the company, the WKP13S is for use on steels such as high alloy, bearing and carbon steels as well as gray cast irons, ductile irons and compacted graphite cast irons, and grade delivers wear resistance and cutting speed, especially in continuous cuts; the WKP23S is a universal grade for a variety of applications, from continuous cutting on barstock to machining interrupted cuts and it delivers wear resistance and cutting speed; and the WKP33S provides toughness during unfavorable machining conditions.
