If you’re starting to get on hand with DIYs and learning how to cut using diamond blades, you probably have encountered some new terms. That said, you need to learn and remember them so you won’t feel confused once you see them pop out from DIY guides.

Here are a few terms associated with a diamond blade that you should know:

  • Abrasive – is a term used for materials that are hard to cut such as stone, granite, bricks, and limestone.
  • Angle Grinderis a handheld power tool that uses smaller diamond blades to grind or cut metal. It is also called side grinder or disc grinder.
  • Cost per Footis also referred to as CPF. It is the average cost spent for 1 foot worth of cutting. For example, if a blade is $20 and you get 10 feet worth cutting, then the CPF of the blade is $2.
  • Cutting Depthis the term used to determine how deep a diamond blade can cut. The actual cutting depth varies with the exact blade diameter or the saw type.
  • Dry Cuttingis a type of cutting that doesn’t use water to cool its blade. Thus, diamond blades for dry cutting are designed to have wider space segments to avoid overheating. Dry cutting is also used when the tool is electrical.
  • Gullet refers to the gap between the two segments of a blade. It is designed to remove slurry and dissipate heat caused by friction during a cut. Its size can also have an effect on the smoothness of the cut.
  • Rotations Per Minute (RPM)is a term that refers to the number of rotations your blade in a minute. For example, if you’re using a blade at 7000 RPM, this means that the blade will rotate 70 times per minute.
  • Slurry – refers to the material that is left after being the cut. In wet cutting, the texture of this material appears similar to mud and is called sludge.
  • Turbo Blade – is a diamond blade designed with a serrated type of segments so it can handle fast-cutting. It also provides the best cutting performance out of all diamond blades.
  • Wet Cutting – is the opposite of dry cutting. It is when the saw equipment tool uses water to cool the blades. This method is often used for long, continuous cutting tasks and for materials such as thick tiles, bricks, and reinforced concrete.
