A concrete saw cuts through rock, cement, and any other type of material. With hardwood being so expensive these days, you’ll want to make sure your steel blade is sharp enough to get the job done.
The “when is it too late to cut concrete” is a question that has been asked before. The answer will vary depending on the type of saw and the material being cut.
A 7″ circular saw, for example, can only cut to 14 inches deep, requiring you to smash the remainder of the concrete away; on the other hand, a 14″ wet-cutting blade coupled to a concrete-cutting saw can cut to 4-5/8 inches of clean cut.
How deep can a 14 concrete saw cut in this manner?
Our 14-inch saws can cut up to a 4-inch depth. This saw may be used to score concrete for jackhammer slab removal, to make expansion cuts in new concrete slabs, and to cut asphalt.
Aside from the aforementioned, how do you cut thick concrete? For modest jobs, use a regular circular saw with a corundum or diamond blade. For slabs, it’s preferable to cut through the top inch and then break off the remainder with a sledgehammer. Below the cutting line, a jagged edge is left to offer a nice rough edge for the fresh concrete to attach to.
Also, how much concrete can a 12 inch concrete saw cut?
On work sites, the most typical saw is a gas saw with a 12-inch depth of cut. Hydraulic diamond chainsaws can cut to a depth of 25 inches. On a cut-off saw, a 14-inch circular blade is intended for a maximum depth of little less than five inches.
When is it OK to saw cut concrete?
Saw cutting cuts joints as soon as the concrete is firm enough to prevent the saw blade from chipping the edges abutting the cut. Cutting joints as soon as possible is sufficient. If seams are not cut within 6-12 hours after completing concrete, concrete may break in hot weather.

Is it possible to cut rebar with a diamond concrete blade?
The torment of bits and blades alike, rebar is the backbone of concrete construction. When cutting exposed rebar, a diamond blade will make rapid work of the job, but it will drastically diminish the blade’s life. Diamond blades “cut” the material by grinding it, as opposed to conventional blades that rip and shred it.

When it comes to expansion joints and control joints, what’s the difference?

How many saws were used to cut concrete?
While experience can help you figure out what works best for your concrete and environment, there is a general guideline to follow. Cuts should be around 2-3 times the slab’s thickness in feet. A 6″ slab, for example, would have cuts spaced 12′ – 18′ apart.
