GX Tiger·tec® CVD Grooving and Parting Grades come with silver flank face.

Press Release Summary:

GX Tiger·tec® Silver CVD Grooving and Parting Grades are offered in WKP13S, WKP23S and WKP33S models. These unit’s Silver CVD coating features aluminum oxide for maximum crater wear resistance and improved cutting speed. The WKP13S model is used in high alloy, bearing and carbon steels whereas WKP33S offers maximum toughness. WKP23S Universal grade is used in application ranging from continuous cutting on bar stock to machining interrupted cuts.

Original Press Release:

New Grooving and Parting Grades from Walter Boost Cutting Performance while Maintaining or Improving Tool Life

Walter Cut GX Tiger·tec® Silver technology features an optimized microstructure for maximum wear resistance and faster cutting speeds.

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

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

The WKP13S is for use under good machining conditions, primarily on steels such as high alloy, bearing and carbon steels as well as gray cast irons, ductile irons and compacted graphite cast irons. This grade delivers excellent wear resistance and cutting speed, especially in continuous cuts. WKP23S is a universal grade for a variety of applications, from continuous cutting on bar stock to machining interrupted cuts. It delivers superior wear resistance and cutting speed. WKP33S provides maximum toughness during unfavorable machining conditions.

Walter, a global leader in the metalworking industry with over 90 years of experience in precision cutting tools for milling, drilling, turning, boring and specialized tools, helps customers improve process reliability and increase productivity. With Regional Headquarters in Waukesha, WI, Walter markets its competence brands Walter Valenite, Walter Titex, Walter Prototyp and Walter Multiply through a strong network of distributors and field engineers across subsidiaries in the USA, Canada, Mexico, Brazil and Argentina.
