Circular Saw Concrete Blade Buyer's Guide
Material Quality
When looking for the best concrete blades for a circular saw, check if it’s high-carbon steel or carbide [1]. Steel blades cut softwood efficiently but wear off quickly when slicing through hardwood. Carbide is more ideal because it retains the cutting edge longer.
Cutting Depth
A blade’s cutting depth is influenced by its number of teeth. Blades with a higher tooth count, like 100 or more, offer better cutting performance. They can achieve deeper and smoother cuts compared to blades with fewer teeth.
Precision
The teeth number and kerf also play a huge role in precision. Blades with a low tooth count cut rapidly, but leave wood waste, compared to those with a higher number of teeth. The thinner the kerf, the better the finish.
FAQ
How long will a diamond blade last cutting concrete?
A diamond blade will last between 12-120 hours on the go cutting concrete. The duration depends on the quality of the blade.
