The BIHUI Cooling Wax is designed to extend the lifespan of diamond drill bits by reducing heat buildup and friction during dry drilling. Ideal for use with BIHUI Diamond Hole Saws up to 12mm in diameter, this 50ml pot of cooling wax is suitable for drilling through tough materials such as natural stone, porcelain, marble, and granite. Simply switch off the drill and dip the core bit into the wax for a few seconds to achieve effective cooling.
