A circular saw is one of the most preferred cutting tools used for cutting wood, metal, plastic, and many other materials, especially in carpentry, furniture manufacturing, and the construction industry. In this guide, we will discuss in detail what a circular saw is, its types, areas of use, and the important features to consider when choosing the best circular saw.

What is a Circular Saw?

A circular saw is an electric or mechanical tool designed to cut wood, aluminum, PVC, and certain metals using a circular metal blade with sharp teeth. It can mainly be categorized into two types: handheld and table-mounted models. Circular saws are widely used by carpenters, furniture manufacturers, and construction professionals.

What Is a Circular Saw Used For? Areas of Application

Circular saws provide fast, precise, and clean cutting on various materials. Main application areas include:

• Wood Cutting: Plywood, MDF, chipboard, parquet, and timber cutting

• Metal Cutting: Aluminum, copper, and thin sheet metal cutting

• Plastic & PVC Cutting: Pipes, panels, and laminate cutting applications

• Carpentry Works: Furniture production, door and window manufacturing

• Construction & Decoration: Floor covering and wood panel cutting

Straight, angled, and deep cuts can be easily performed with a circular saw. Models equipped with guide rail support enable more precise and stable cutting operations.

Types of Circular Saws

Circular saws are divided into different categories according to their usage style and cutting capacity.

1. Handheld Circular Saw

• Portable and lightweight structure

• Available in corded and cordless models

• Operates within a power range of 750W – 1500W

• Ideal for home renovation and small-scale jobs

2. Table Circular Saw (Stationary)

• Provides high cutting performance

• Used for cutting large and thick materials

• Preferred in professional workshops

3. Metal Cutting Circular Saws

• Equipped with special hard metal teeth

• Suitable for cutting stainless steel, aluminum, and copper

4. Combined Circular Saws with Jigsaw Function

• Can perform both straight and curved cuts

• Offers versatile usage advantages

Circular Saw Features: How to Choose the Best Model?

Here are 6 critical features to consider when buying a circular saw:

1. Blade Diameter

• Varies between 165 mm – 350 mm

• Large-diameter saws (250 mm+) can cut thicker materials

2. Tooth Structure and Number

• 24–40 teeth: Fast and rough cutting (ideal for wood)

• 60+ teeth: Smooth and fine cutting (ideal for laminate and PVC)

3. Motor Power

• Should be within the range of 500W – 2000W

• Higher wattage means more efficient cutting performance

4. Cutting Depth

• 90° straight cutting: Standard feature

• 45° angled cutting: Available in professional models

5. Safety Systems

• Lock protection: Provides sudden stop safety

• Dust extraction connection: Ensures a cleaner working environment

6. Additional Features

• Laser guide: Makes precision cutting easier

• Adjustable speed control: Can be optimized for different materials

Important Considerations When Using a Circular Saw

• Always use protective goggles and gloves

• Select the saw blade according to the material being cut

• Do not force the machine during cutting; allow it to progress naturally

• Extend the machine’s lifespan with regular maintenance such as sharpening and lubrication
