Using water or water-based coolants in a slab saw is generally not recommended and may void the warranty on our Highland Park machines. However, we understand that certain materials require water cooling to prevent discoloration during cutting.
While HP occasionally use water when cutting, it is not suitable for harder stones like agates and jaspers. These dense materials perform better with oil-based coolants, as water does not provide adequate lubrication or cutting efficiency.
Water-based coolants may be necessary when working with softer or more sensitive materials that are prone to heat-related discoloration. If you choose to run water in your slab saw, proper maintenance is essential to prevent damage.
Follow these steps to minimise wear and extend the life of your equipment:
Always drain your slab saw at the end of each day. Installing a ball valve can make this process quicker and more efficient.
Leave the hood open and use a clamp-on fan to dry the interior. This helps reduce moisture buildup and prevents rust from forming on metal components.
Apply a light oil such as WD-40 to all exposed metal parts, including:
This should be done after every use to prevent corrosion.
Diamond lapidary blades dull faster when used with water compared to oil-based coolants. Regular sharpening will maintain cutting performance.
Using water-based coolants can lead to long-term damage, including:
For this reason, we recommend keeping replacement parts on hand. We also provide instructional videos to assist with maintenance and rebuilding.
While running water in a slab saw can be helpful for certain materials, it comes with increased risks. Proper care, routine maintenance, and understanding your material type are key to avoiding costly damage.
