A circular saw can cut wood, stone, plastic, and metal, among other materials. It can be operated with a machine or held in one’s hand. The term “circular saw” is used in woodworking to refer to the hand-held version; however, circular saws also include table saws and chop saws.

The mobility of a circular saw over a table saw is its most significant advantage. They’re portable, and you can use them to chop wood even if transporting the wood to the tool isn’t an option. It’s a power saw that cuts various materials with a rotary motion around an arbor or abrasive disc or blade.

It uses a rotational motion spinning around an arbor to cut various materials with an abrasive disc or blade. Although they all rotate, a circular saw is not the same as a hole saw or a ring saw. A circular saw can also be used to create the blade.

Benefits of Circular Saw   

  • Portability: It’s not limited to a single location, like a table saw. It is also lightweight, weighing around eight pounds. If you use the cordless version, you won’t have to worry about running out of power. You will no longer have to be concerned about tripping over cords.
  • The versatility of cuts: It can perform a variety of cuts with the same blade, such as bevel, plunge, cross, finish, and so on, without having to change it. This level of adaptability is only matched by a few tools.
  • Added features: They, for example, have an LED light that enables them to be used precisely even in low light. They also come with a fast charger for quick charging.

Limitation of Circular Saw

  • They have a proclivity for producing a lot of sawdust, which necessitates more frequent vacuuming in the workshop. Where circular saws fall short is in the precision with which they can make cuts.
  • When operated by a skilled operator, a circular saw can make straight and precise cuts. A beginner, on the other hand, will find it much more difficult to do this by eye.

Wide range of Application

Circular saws are popular among carpenters because of their ability to make precise and quick cuts. A good circular saw is ideal for DIY woodcutting projects. It’s used to cut bevels, large-scale timbers in sawmills, metals, logs into firewood, straight cuts, crosscut plywood, and cut down long plywood.

How to Cut a Straight Line with a Circular Saw?

Step1: Clamp the Wood

Securing or clamping the wood will allow you to focus on the cut rather than the wood. Many times, you can cut any wood with a circular saw without clamping it, especially if you’re a seasoned circular saw a user or the weight of the wood or board you’re cutting makes it nearly impossible for it to shift during the cut.

Clamping and securing the board before cutting, on the other hand, is always a good idea. This will keep it from shifting out of line while cutting, allowing you to get the most out of both the saw and the wood, resulting in straighter cuts.

Step2: Hold the blade properly

In the same way that there are different types of circular saws, there are correct and incorrect ways to hold one. The way you hold it will have a big impact on how the cut turns out. Circular saws are divided into two types. Right-hand circular saws and left-hand circular saws are available.

Right-handed circular saws are for right-handed people, and left-handed circular saws are for left-handed people. Although not using your hand type allows you to see the cutting blade better, using your hand type allows you to hold it more securely without your hands crossing over.

Step3: Set the appropriate depth of cut

Setting the proper depth of cut with your circular saw is the first step in making a straight and accurate cut. The blade may deviate from the straight part of the cut if the cut depth is incorrect, resulting in a skewed cut. Aside from that, cutting without the proper depth of cut is not very safe. You should adjust the blade so that it only protrudes a quarter of an inch from the bottom of the wood you’re cutting.

Step4: Use a circular saw guide

A circular saw guide, such as the Kreg rip-cut guide, is your best bet if you’re a beginner and want to make perfect cuts every time. You won’t have to measure anything or draw a straight line to mark the cut line if you use a guide. All you have to do now is set the Kreg reg circular saw guide to the desired width and cut. It’s ideal for repeat cuts, straight rip cuts, and, most importantly, straight cuts every time the circular saw is pushed along the slide.

Step5: Cut with the good side of the board facing down to avoid splinters

If you cut across the grain of the wood, you’ll end up with splinters at the top. Always cut with the good side of the board facing down to avoid damaging the good side of your wood. This way, if there are splinters at the top, they will be hidden after you’ve finished assembling your project.

Step6: Before cutting, let the circular saw blade reach full speed

This is a critical step that must be completed before making any type of cut. Allow the blade to reach full speed before bringing it into contact with the wood you’re cutting after you’ve compressed the saw trigger. Otherwise, the blade will leave a mess on the wood’s edge as it cuts through it. As a result, before cutting, always let the blade reach maximum speed.

Safety Tips

  • Avoid wearing loose-fitting clothing and use safety glasses and hearing protection. Tie back long hair.
  • Set the saw blade to cut 1/4 inch deeper than the thickness of the wood.
  • Nails are used to secure boards less than 6 inches wide, and clamps are used to secure larger boards.
  • When you’re cutting, stand beside the blade rather than behind it. Bystanders should stay away from the area behind the saw.
  • If the board starts to pinch the blade and cause it to bind, wedge it open with a shim.
  • Inspect the blade guard for proper operation. It should never be blocked or wedged in the raised position.


How to Cut a Straight Line with a Circular Saw?

Circular saws, like other saws, are useful for a variety of tasks. You can get the saw to perform some of the most unusual cutting operational processes for you with a little patience and technique. To learn how to cut straight lines with a circular saw, simply follow the steps outlined above.


  1. When using a circular saw, where do you cut a line?

Cut with the good side facing down when appearance is important, as circular saws can splinter the wood on the top side. Splintering can be reduced by using masking tape as a cut line. If you notice that you’ve strayed from the cut line, instead of attempting to curve your way back on track, start over.

  • Do circular saws have the ability to cut upwards?

Circular saw blade teeth are designed to cut upwards into the material from below, which is for safety reasons. You mustn’t them in the opposite direction as you would a table saw blade.
