Required Tools for Cutting

  • Some clamps
  • A competent blade
  • A speed squares
  • A scale
  • A pencil
  • (and of course, a) circular saw itself

Step 1: Get Shielded First

Before you hit any power tool – no matter what type- getting the necessary safety initiative pays a lot in the long run.

Dealing with a power tool means exposing you to sharp blades and rough wood pieces, potentially injuring you.

Get a pair of glasses, gloves, earmuffs and even a medically approved respirator mask to get protected from all kinds of security threats.

Step 2: Prepare the Saw

The fits-in-all rule for all power tools is to check if the machine works correctly, the sound is not strange, and the machine parts are secured, keeping them in due place.

When it comes to a circular saw, check the saw in general and that the blade is in good condition. If they show no indiscipline, proceed with the piece to cut. Plug the saw or insert the battery to turn the saw.

Step 3: Configure the Blade

You know how smoothly and accurately a saw can perform if it is configured with the right saw. So, you’ll have to get a blade that can rip 2×4 with a circular saw desirably. A blade with 40 teeth or more is better for cutting wood, which ensures clean and cutting quality.

Setting the blade depth for cutting depends on the type of materials. When it comes to a 2×4 piece, don’t set it too deep. It doesn’t bring any good results rather it puts you in trouble, causing kickback.

Before you hit the saw, don’t forget to check the blade guard. It’s another important safety protection you shouldn’t start sawing without. It’ll save you from direct contact with the spinning blade.

Step 4: Support One Side of the Piece

There is a tendency to support the piece to protect it from splintering the fallout at both ends with clamps. Most beginners fall into this trap. But it doesn’t serve any safety and accuracy in the process in most cases. Sometimes, it causes kickback by letting the piece bend downward.

However, if splintering is possible, you need to get alerted to protect it by clamping one side of the wood. Clamping one edge of the wood on the table or surface will secure the workpiece and let you practice maximum strength and control.

Step 5: Straight Cut

You will practice the final step for cutting 2×4 with a circular saw. It’s time to use a scale and pencil to draw the exact line to help you get the precise cutting. It’s a must-do step for beginners; professionals sometimes can avoid it through their experiences.

When you start the straight cut with your circular saw, remember ripping 2×4 with a circular saw must require enough scale of energy, be it corded or cordless. Apart from the capacity, you should have all the cutting hacks in your mind, for example, when you need to stop the saw or take a break.

If the saw goes in the wrong direction, leaving the exact line of cutting, don’t forcefully bring the saw back onto the line. Instead, stop sawing and start from the beginning.

To prevent such complications, you had better use a speed square for the exact dimensions of a 2×4. A competent speed square will make the process more accurate, mapping the line and helping you walk along the line.

You can use it by holding it or clamping it to the table.

Short Notes

  • Start with adequate safety protection.
  • Don’t use a blurred blade.
  • Use an appropriate woodcutting blade.
  • Approach slowly through the line.
  • Use a scale and pencil to draw a line.
  • Use a speed square to guide the line of cutting.
