One of the biggest problem with Diamond blades is overheating. The resources available to you will play a important role in deciding what saw blade to choose. The segmented blade is really good when you don’t have access to water cool your blade. Usually this style of blade is divided into 8,9,10 or 16 segments with a deep groove in between each section. As mentioned before, this blade is great option for when you don’t have access to water because the grooves in the steel core allow for sufficient heat transfer. If you are not careful while cutting you can overheat the blade. If this happenes, the blade will warp and will no longer be usable.
