ROCTEC Waterjet Nozzles/Mixing Tubes

ROCTEC abrasive waterjet (AWJ) nozzles (sometimes called mixing tubes or focusing tubes) have provided unrivaled cutting performance for over 30 years.

Made using Kennametal’s proprietary material and process technology, ROCTEC nozzles are extremely durable and resistant to abrasive and erosive wear. The manufacturing process ensures consistency in each nozzle, eliminating the need to reprogram a job when replacing a nozzle.

Users experience longer cutting periods while maintaining precision performance. Choose from three styles of ROCTEC AWJ nozzles: 100, 500 and APX.

ROCTEC APX delivers the longest, most reliable period of precision cutting in the industry.

  • No premature nozzle failure and parts scrap

  • Fewer nozzle changes for greater uptime

  • Predictable accuracy cut after cut

  • Faster production speeds and longer production periods

  • Extends nozzle life as much as 20% greater than ROCTEC 500

Systematically outperforms all other abrasive waterjet nozzles

ROCTEC 500 Nozzles

ROCTEC 500 is the most trusted waterjet nozzles for consistent, long-duration, precision cutting.

  • 24 times greater wear resistance than tungsten carbide/cobalt nozzles

  • Superior bore growth improves accuracy and tolerance levels

  • Faster cutting speeds compared to ROCTEC 100

  • Longer nozzle life, less downtime
  • Typically last 30% to 40% longer than ROCTEC 100

Ideal for:
• High-pressure cutting
• Precise, uninterrupted cuts
• When edge quality is critical
• Waterjet tables with multiple cutting heads

ROCTEC 100 Nozzles

ROCTEC 100 is the waterjet cutting industry workhorse for general applications.

  • Fit-for-use performance

Ideal for:
• Rough cutting
• Moderate to high-pressure cutting
• Non-metallic materials
• Pure waterjet

The ROC Process

ROCTEC composite carbide is a tungsten carbide-based material made by the patented Rapid Omnidirectional Compaction (ROC) process exclusive to Kennametal.

This process enables these advanced ceramic materials to be combined without using a soft metal binder and with very short consolidation cycles – minimizing the natural tendency of ceramic particles to enlarge when exposed to high heat for long periods.

Maintaining extra-fine grain size means better nozzle performance resulting in an extremely durable material that fiercely resists abrasive and erosive wear.

Superior Wear Resistance & Greater Accuracy

Superior wear resistance means a reduction in the number of AWJ nozzles purchased over time. Longer AWJ nozzle life also results in a better jet pattern and increased velocity. This means faster average cutting speeds and significantly less downtime for nozzle replacement and system calibration.

This also translates to greater dimensional accuracy and the ability to perform longer, uninterrupted cuts. These enhancements ensure a more cost-effective cutting process.

All leading abrasive waterjet system manufacturers design their systems with ROCTEC AWJ nozzles (also called mixing tubes or focusing tubes).

  • Consistent and long service life
  • Superior wear resistant
  • High hardness Vickers 25.5-27.7 kg/mm2
  • Longer service life than tungsten carbide

Comparative testing documents the extended service life provided by ROCTEC nozzles/mixing tubes versus products made from tungsten carbide/cobalt.
