A circular saw is an affordable, versatile type of saw that’s ideal for various home improvement projects. However, learning to properly use a circular saw is necessary to ensure the best project results.
Circular saws are handheld saws with a powerful motor, a large cutting blade, and a trigger to activate the blade. They’re typically held by a handle in one hand, though some models have a secondary grip near the front of the saw to steady the blade. Use this guide to learn more about circular saws and how to use one for your next home renovation project.
Parts of a Circular Saw
Before using a circular saw, it’s a good idea to understand its various parts, including the handle, trigger lock switch, front grip, shoe, and more.
- Handle: Grip the handle to lift, carry, and control the tool. The trigger is located in the handle, making it easy to activate the blade with a squeeze of your finger.
- Trigger Lock Switch: Since the saw is so easy to activate, manufacturers usually include a trigger lock switch to prevent the user from accidentally turning on the blade. Press down on the trigger lock switch before squeezing the trigger to activate the blade.
- Front Grip: At the front of the saw is a secondary handle for the user to grip. It improves the user’s control of the saw.
- Shoe: The shoe refers to the metal plate at the base of the saw.
- Blade Guard: The large cutting blade has a retractable blade guard that covers the circular saw blade when the tool is not in use. The blade guard retracts to allow the saw to cut through the target material.
- Power Source: Corded circular saws use a power cable to connect to a nearby power outlet, while cordless circular saws use a rechargeable battery to power the tool.
- Bevel Adjustment Knob: This knob changes the angle between the shoe and the saw blade, allowing the circular saw to make angled cuts.
- Depth Lock Knob: Use this knob to determine how low or high the blade sits in the saw. The lower the blade, the deeper the cut.
Safety Tips
When using a power tool, proper safety precautions are essential to avoid injury. Precautions are especially important when learning to use a new power tool like a circular saw. Wear safety glasses, hearing protection, a dust mask, gloves, long pants, closed-toe shoes, and a long-sleeve shirt. Also, keep long hair tied back and avoid wearing loose jewelry or clothing.
Next, prepare the area where you will work. Clear a place on a stable surface and inspect the circular saw to ensure there are no problems. This should include checking the safety features, blade, blade rotation, depth setting, and bevel setting. For the best results, select the saw blade based on the type of material being cut.
When operating the saw, wait for the blade to reach full speed before cutting through the material. Don’t try to twist the blade or force the saw while cutting. Frequently check for obstructions in the material, like staples or screws, and keep two hands on the saw to improve control and stability. After you finish with the saw, unplug it or remove the battery to avoid accidental activation.
