Grader Edges
Plasma Wear Parts supplies long-life grader edges and grader blades engineered for Australian mining operations, with a focus on WA iron ore, hard-rock, and haul road conditions. Our aftermarket grader blades deliver extended wear life, fewer changeouts, and more consistent fleet uptime across Caterpillar, Komatsu, and other major OEM machines.
Built for high-abrasion haul roads and continuous production environments, our extreme-wear grader edge systems help sites reduce downtime, improve road safety, and lower cost-per-hour. If your operation needs durable, mining-specific grader blades, Plasma Wear Parts provides proven solutions designed for tough Australian conditions.
Grader Link™ - Safer, Faster, Longer-Lasting Grader Blades
Grader Link is a patent-protected grader blade system widely used in North and South America and now available for Australian mining operations. Designed for heavy haul roads and high-abrasion conditions, it addresses the challenges mine sites face every day: safety risks during blade changes, frequent downtime, and costly, uneven wear.
Safe & Easy Fitment
Traditional grader blades are heavy and awkward to handle, often requiring multiple fitters or lifting equipment. Grader Link blades are just 30.5cm (1 foot) long and weigh a maximum of 20.9kg, allowing a single fitter to install or replace them safely. This reduces the risk of injuries and keeps your maintenance team productive.
Improved Rigidity & Blade Alignment
Blades use a dual Nord Lock washer system that locks each part firmly in place. This eliminates movement or misalignment during operation, reducing uneven wear and protecting grader performance. Backed by a lifetime warranty on the locking system, it ensures reliability and fewer blade-related interruptions on site.
Extreme Wear for Long-Life Performance
Grader Link combines tungsten carbide overlays and inlays for superior wear life. The result is fewer changeouts, lower blade costs, and more time spent grading rather than replacing edges. Your fleet stays productive, and your haul roads remain consistent and safe.
X-TREME GRADE™
X-TREME GRADE is a patent protected grader blade system that is extensively used in North and South America. The innovative solution is one of the world’s most advanced grader blade systems.
This is an excellent solution for mining operations using serrated blades on CAT 24 or similar graders looking for improved productivity and lower costs. The key points of difference are:
- Reduced waste
- The unique design enables boards to last a full 12 months without requiring replacing
- Instead of replacing the entire serrated edge you only need to replace the bits reducing huge steel waste
- Lower procurement costs
- Replacing the bits is far more cost effective and can reduce costs dramatically
- Reduced downtime
- With only the small 1.8kg bits needing to be changed, changeover times are reduced by more than half
- The longer wearing solution reduces the total changeovers required and reduces fitters exposure to risk
- The lighter bits are far safer to handle and replace than 150kg edges which are only refitted annually
This system is not the 1 foot sectional product for smaller graders. We offer 4-foot boards which are required to handle the larger bits that are fitted to a CAT 24 Grader.
Bits are available in rotating and non-rotating versions.
Tungsten Tough – Long-Life Grader Blades for Traditional 4-Foot Fitments
For sites that prefer the familiarity of standard 4-foot grader blades, Tungsten Tough delivers the same triple-carbide technology as Grader Link, but in a format designed for traditional installation practices. This allows fitters to work quickly and safely with blades they know, while still benefiting from extreme wear life and reduced downtime.
Reliable Performance with Standard Fitment
Tungsten Tough provides a cost-effective, high-performance alternative to Grader Link, making it ideal for workshops that want consistent, predictable blade installation without retraining staff. It’s also a practical solution for trialling advanced wear technologies before transitioning to safer, lighter systems like Grader Link.
Wear Life Designed for Your Site
Every set of Tungsten Tough blades can be customised with tungsten overlays and inlays based on your site conditions, haul road type, and previous wear profiles. This tailored approach ensures your grader edges deliver maximum life, minimise changeouts, and keep your haul roads safe and productive.
