The segmented diamond blade is also known as a dry cut blade and is mostly used on dry cutting applications. Air flow cools the blade by making use of segments and cut-outs (gullets) in the body of the blade to dissipate heat.
The segments also have improved clearance of debris to allow for a quicker cut with a relatively smooth finish, however chipping may occur.
Segmented blades are the best option when water isn't available. The blades are durable and have a long life compared to other blades.
- Make multiple shallow cuts instead of a single deep cut
- Do not side grind a cutting blade
- Fit the blade in the correct rotation direction
- The life expectancy and cutting performance of the blade will be reduced when fitted reversed
- It is also prone to becoming glazed
- When a diamond blade is glazed, it feels smooth to the touch with little to no diamonds exposed
- This happens when the metal bond on the segment is too hard for the material it is cutting
- To rectify - expose more diamonds on the segments by making shallow cuts in a soft, abrasive material like limestone
- A short diamond blade life is a result of using a blade with a soft metal bond on a more abrasive material such as sandstone or asphalt
- Wet cutting will extend the life of the blade
