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

Cutting depth depends on the number of teeth on the blade. A blade with 100 or more teeth will cut better than those with less. The more the teeth, the deeper and smoother the cuts.

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.
