How Deep Can a Circular Saw Cut? – [Depth Tables]

The circular saw is used for a wide range of cutting depth in woodworking. It is very important to know about cutting depth because when the saw blade is inclined its cutting depth also varied with the angle. So let’s see how much depth a circular saw can cut?

Circular saw cutting depth depends on the shoe and motor height and flanges diameters. When those are higher it can cut lower depth. So 4 1/2″ blade can cut 1 11/16″, 5 1/2″ blade can cut 1 3/4″, 6 1/2″ blade can cut 2 1/8″ and 7 1/4″ blade can cut 2 1/2″ of maximum depth of cut.

So let’s see how each blade can cut with various inclined angles.

How to Measure The Circular Saw Cutting Depth?

We can calculate the cutting depth of the circular saw blade by using its maximum cutting capacity and inclined angle.

Cutting Depth = Maximum Cutting Deth x Sin (Cutting Angle)

The cutting depth will vary with cutting angle
Maximum cutting depth will be in 90 degree

How Much Depth Can a 4 1/2″ Circular Saw Blade Cut?

A 4 1/2″ circular saw blade can cut a maximum of 1 11/16″ of cutting depth when the saw blade angle is 90 degrees. Other angles will be varied like this.
