A plunge cut is a type of cut you make with a handheld circular saw that starts and ends in the middle of a piece of wood.  Below is a short series of paragraphs detailing how to properly make a plunge cut.

Step 1: Measure Precisely

There is no second chance to correct an incorrect cut. Make sure you measure extremely precisely and use the same precision when transferring your measurements to the board being cut. Once you’ve transferred your measurements to your target piece of wood, lay it out securely on your sawhorses.

Step 2: Set Depth of Cut

Sometimes when making a plunge cut, going all the way through the wood isn’t desired.  If this is the case, make sure you set the proper plunge depth.

Step 3: Cut

Once you have the dimensions of the proposed cut laid out on your project, it’s time to make your cut. Place the saw in the middle of the cut and line up the guide with your line. Squeeze the trigger and slowly lower the blade into the wood, allowing the cut of the blade to pull the saw through the wood. Once the desired depth has been reached, carefully cut along your previously drawn line, from one end to the other.


One common mistake people make when making a plunge cut is not wearing safety glasses. Another mistake commonly made is what is known as over-cutting, or cutting beyond your lines. And lastly, people often forget to check their plunge depth.

In the above paragraphs, you have been given some easy to follow instructions to use and mistakes to avoid when making a plunge cut with a circular saw.
