high grade professional diamond construction

Concrete can also be cut with stainless steel cutting discs but diamond blades are recommended, for diamond blades can provide at least two times faster cutting, less downtime, and constant depth of cuts.

If you use the diamond construction occasionally and your jobs are small, you can choose the economical grade diamond blades to save your expense (but the cutting speed of the economical diamond blades should be fast enough). If you use the diamond blades frequently or the job is big, you should choose high grade professional diamond blades, for this can decrease your cost per cut.
