How to Choose the Proper Electric Concrete Saw
If an electric concrete saw is selected, the circular saws with 7¼ to 5⅜ inch blades are ideal for general use. And even though a wired electric saw was once required to obtain the power needed to cut plywood and 2 × 4 lumber. The successful carpenters prefer today’s wireless circular saws that can handle that kind of work and operate all day with a single charge.
Now you have a circular saw that can rotate its blade at approximately 5,000 rpm. But what else can you expect? The base plate can be adjusted to the desired depth of cut or tilted to make an angled cut, which is typically 45 degrees for a miter joint. The plate can be fixed with a screw or lever (for speed adjustment, the lever is better) and some models have a scale so you can quickly read the depth and angle of cut.
The platforms have a notched pointer edge to guide the saw along a line. Some have a laser to guide the saw along the cutting line, although this function does not help much if the tool is used in bright sunlight. A safe on the shaft makes it easier and faster to change the cutting blades of the saw of the construction circular saw.
