How to choose the best circular saw?

First of all, you can buy a circular saw with the following parts and features:

Everything about the saw blade
  • The blade size

Depending on the model you choose, the saw blades have the right size.

For example, the portable circular saw usually comes with a 4 1/2 inch blade, while a full-size ones use a 7 1/4 inch blade.

But wait – there’s more thing you should know about the blade.

The power of the engine provides the ability to operate efficiently on the saw blades.

The 1HP engine with a 7 1/4 inch blade will help you with the use of many different materials. However, the blade will sink to the hard items.

Meanwhile, the same blade at the end of a 2HP+ drivetrain will be a good helper for you in this case.

  • The blade ability of adjustment

The standard circular saw can easily adjust the depth of the cut that you desire.

The cuts are about 2 3/4 inches deep, or mostly for 2 1/2 inches.

Most importantly, the depth adjusting feature affects your experience with the circular saw.

Think about this for a moment.

You need to hold the saw to adjust the depth of how much is appropriate, or you want to change from 90 degrees straight cutting to the tilt of 22.5 degrees or the angle of 45 degrees easily.

It all depends on the adjustment mechanism of the blade.

We have one tip for you. When you want to buy online products without knowing it is a good use or not, you ask people with the same carpentry hobby that possesses the right engine for you to try and see how it feels.

  • The material of the blade

If you use a hard material such as steel, there must be an HSS (M2 high-speed steel) blade or carbon steel depending on the material you need to cut.

If you cut most of the wood items, the suitable material is tungsten carbide, or maybe HSS but cheaper.

Let move on the second important thing about a circular saw.

  • The saw power

Circular saws are a useful product when it is possible to cut through any hardwood pieces without grinding to stop or slow down significantly. If you need a good performance saw, choose a motor of 15 amp power.

  • The weight of a circular saw

When using heavy saws, you may not need much strength to cut hard materials, but for the whole day, you will feel dissipated. Let try an 8-pound saw and 12 or 14 pounds saws, and you’ll see the difference right away.

How to use the circular saw easily

Frankly speaking, a heavier power saw can cut quickly through the toughest material while you need to push more for the lighter one.

However, there are many other aspects to consider when using the saw efficiently including:

  • The saw blade must be easy to change.
  • The power cord doesn’t cause problems when you are using a saw to cut.
  • The machine needs to be appropriately balanced.
  • The laser or LED light in the front helps you to see clearly.
The battery and power cord

The battery is best for portable circular saws. With technological advances, battery tools deliver excellent performance regarding productivity, mobility, and convenience.

As for full-size circular saws, you’ll need a long cord to avoid getting caught while using the saws.

The saw durability

For the durability of this product, you need to consider its base plate.

It is the most breakable part. So if the manufacturer supplies a good base plate, it means that they focus on the durability of the product.

If this part is made of stainless steel or aluminum, you may not use the saw for a long time. You should choose a baseplate with durable plastic or fiber reinforced.

Other important features

You may consider choosing the following characteristics of a circular saw:

  • To see the cut line, you need a laser or LED illuminated in front.
  • When you want to blow away the sawdust, you can buy a saw with a blower or vacuum.
  • Or you can also use a saw with automatic braking blade.
  • With a battery-operated saw, it’s great to have a battery life indicator to help you know when to charge the saw.

Now you can understand which features of a circular saw you need, keep reading and you will know the steps to use this tool.

How to use a circular saw?

Here’s all you have to do, let follow these steps:

  • First, you need to put the wood on a solid surface.
  • You will cut through the grain with a crosscut and cut with the grain when you want a rip cut.
  • You need to clamp 1×4 onto the sheet to act as a guide for the blade when using a saw with a large plywood piece. Or you should draw or use a speed square to set the line on the wood.
  • Next, you adjust the cutting depth.
  • Note that you have to put down the wood pieces well.
  • You turn on the power before cutting with electric circular saws while with a portable one, you should check the battery carefully.
  • Remember that the technique to push the blade of the saw is to rotate through the end of the woodcut continuously and decisively, no stop in the midway if possible.
  • Pay no attention to the pieces of wood that fall off when you cut, let them fall to the floor. 

Some safety tips when using a circular saw

With a blade-sharp and electrically-operated product, it is essential to grasp the principles of safe use.

That’s why we offer the following safety tips.

Seven things you should do include
  • Wear eye protection to avoid sawdust or wood splinters from your circular saw.
  • Check the blade sharpness to make sure they cut more easily.
  • Unplug the electric saw or remove battery from portable saw before changing the blades.
  • Carefully research the surface to be cut without staples, screws, and nails.
  • Read the manufacturers manual when purchasing new saws as they will regularly change their product and how the saws operate.
  • Warning: The blade has entirely stopped before placing it down or releasing one of your hands. Many saws have an electric brake system for the blade to engage immediately after the trigger is released.
  • You just put the saw down or release your hand when making sure the blade has stopped completely. You can buy the saw with automatic braking for the blade after the trigger release.
Four things absolute avoid doing include
  • Do not wear loose clothing, have long hair down the saw or jewelry easily stuck in the blade. Just in a second, these things can make you stick to the sharp-edged blade that is spinning rapidly and cause injury poorly.
  • Do not stand right after the power saw, and you will be hit by the wood chips when the saw works. It’s better to stand aside.
  • Never use a circular saw with one hand, hold and use two hands firmly.
  • Do not change the power or any part of the saw in any way.
