Concrete Cutting Blade Technology

C oncrete saw blades and bits may look simple, but the technology behind them and experience needed to select the right blade/bit for the job is anything but simple. Blades & bits consist of a steel core or tube and a number of segments that are laser welded to the core. The segments are made from diamond, cobalt, and other hard materials. Blades range in size from four inches up to 84" and cost from few hundred dollars to thousands.

The fewer the segments on the blade or bit, the less friction and the faster cutting times. But this comes at the cost shorter life. The amount of RPMs or speed of the blade or bit is another factor that must be adjusted. And every blade or bit must be kept cool with a water during the cut. If the blade or bit were to overheat, the blade or bit can lose its temper and tension or be ground away. A blade could and end up being as flimsy as sheet metal. Selecting the right blade is an art, and ATI will always test blades & bits, RPM's, horsepower & consult with our industry partners before selecting the best one for the job.

ATI is always working closely with blade & bit industry partners to improve technology. There are all different types of concrete, with the two most common being hardrock and limestone, in which hard rock is definitely the more challenging to figure out. There is also the factor of the psi of concrete along with type & size of steel or rebar embedded in the concrete being cut. All of these elements change from job to job and require knowledge, experience and good working relationships with industry partners to be successful in getting the right blade or bit for each job.
