What are the best practices to extend the life of tungsten carbide mining tools?Even though tungsten carbide is extremely tough, poor operating habits will still destroy it quickly. First, always ensure adequate flushing and dust collection—without proper air or water flow to remove rock cuttings, the carbide will overheat and may spall (flake apart). Second, avoid running the tool against steel objects like worn-out drill rods or casing; carbide cuts rock beautifully but chips badly on steel. Third, do not let the tool "spin in the hole" without cutting pressure, as this generates friction heat without effective rock breakage. Finally, inspect your carbide buttons or picks regularly and replace them as a set once significant wear appears. Running a mix of worn and new tools causes uneven loading and accelerates failure of the remaining carbide. Follow these steps, and you will easily double or triple your tool life.https://www.xymjcarbide.com/products/tungsten-carbide-mining-tools

How does cobalt content affect the performance of tungsten carbide mining tools?The percentage of cobalt binder in a tungsten carbide grade controls the trade-off between toughness and wear resistance. For mining tools, higher cobalt content (typically 10% to 20%) produces a tougher, more impact-resistant grade. This is essential for tools that experience heavy shock loading, such as picks for hard, fractured rock or button bits for roof bolting. Conversely, lower cobalt content (6% to 10%) creates a harder, more wear-resistant grade ideal for drilling soft to medium rock where abrasion is the main failure mode, not impact. If you pick a grade with too little cobalt for an impact-heavy job, the carbide will crack. Use too much cobalt in a highly abrasive formation, and the tool will wear out prematurely.https://www.xymjcarbide.com/products/tungsten-carbide-mining-tools
