Deciding what type of cutting you will need can be crucial to your success. Many factors apply when comparing cutting speed to cutting life. Here are a few to give you a small insight to how you could compare costs & save money in the process:

Faster cutting means less cutting duration. Many people require a faster cut when they rent their equipment and must get the job done in a timely manner.

Faster cutting also save time & labor costs. Aside from the time and labor saved in getting the job done faster you also save money on gas usage. A fast cutting blade will finish the job quickly and with less gasoline than a slower blade.

A faster cutting blade will cost more per cut (per foot/meter), While a slower cutting blade will save you money per cut.

Below is a comparison chart which can help you get a better idea of some of the pros and cons of using different types of blades.

Many factors must be taken into account during the selection process to find a blade suitable for your specific needs. Here are a few examples:

1) What size blade will you need? Chart

2) How much do you have to cut? Cutting Duration

3) Do you need a faster cut or longer life? Chart

4) What is your cost per foot/meter? Calculator

5) Should you switch blades or use a multi-purpose
blade? Depends on cutting variety.

6) Do you need Laser Welded Blades or Sintered?
Depends on the material being cut & safety.
