We are also the leading supplier of industrial blast nozzles for abrsaive blasting applications in North America. Our involvement includes development of custom engineered, cost effective solutions to provide operational efficiencies in spraying, atomizing, mixing, focusing, cutting, drilling, and cleaning.

Our advanced materials are helping to develop new solutions to meet future challenges for solving abrasive, erosive, corrosive, and thermal wear problems.

Abrasive waterjet (AWJ) cutting is one of the fastest growing machine tool processes. This unique cutting process is used throughout industry on a variety of hard materials including stainless steel, steel alloy, titanium, aluminum, stone, marble, granite, and composites among several other hard to cut materials.

AWJ can cut difficult geometric part shapes quickly and precisely without thermal damage to the part, representing tremendous gains in efficiency and productivity. Kennametal nozzles (focusing or mixing tubes) are an integral part of today's precision AWJ cutting processes.

Abrasive Waterjet Cutting Products

Mixing Chambers

The mixing chamber, located in the body of an AWJ cutting head, is subject to extremely abrasive and erosive wear conditions as the focused ultra high pressure waterjet is mixed with abrasive grains prior to its entry into the cutting nozzle (focusing or mixing tube). Kennametal produces custom mixing chambers in ROCTEC® composite carbide as well as K313 grade of sub-micron tungsten carbide.

ROCTEC® 100 Nozzles

ROCTEC® 100 Composite Carbide nozzles are produced from a patented formulation of ultra fine grain carbide materials. This unique "binderless" structure is consolidated in our proprietary ROC Rapid Omnidirectional Compaction Process, thereby ensuring the highest possible quality nozzle as required by the abrasive waterjet cutting industry. Our ROCTEC® 100 nozzles are considered the worldwide standard for reliability and repeatability.

ROCTEC® 500 Nozzles

ROCTEC® 500 Composite Carbide nozzles are produced from a patented formulation of ultra fine grain carbide materials. This unique "binderless" structure is consolidated in our proprietary ROC Rapid Omnidirectional Compaction Process, thereby ensuring the highest possible quality nozzle as required by the abrasive waterjet cutting industry. Our ROCTEC® 500 AWJ nozzles are considered the worldwide premium nozzle for maintaining precision cutting.
