Consult your manufacturer’s instructions for recommended lubricants.
The lubricant for bridge saw is generally held in a reservoir under the saw’s cutting table. The bottom of the saw blade dips into the liquid. As the blade spins, it picks up the lubricant, continually delivering it to the slice being made through the stone.
