Makita cordless circular saw

A cordless circular saw offers the freedom and portability of not being tethered to a power outlet, making it a popular choice for both professionals and DIY enthusiasts. Here’s a breakdown of key aspects to consider when looking for a cordless circular saw.

Key Features to Look For

• Power and Voltage: Cordless saws are rated by voltage, typically ranging from 12V to 60V. Higher voltage generally means more power and torque, allowing the saw to handle tougher materials. Brands like DeWalt offer 60V options for maximum power, while 18V and 20V models are common for general use.
• Blade Size: The most common blade sizes are 6-1/2 inches and 7-1/4 inches. A larger blade allows for a deeper cut, which is essential for cutting through thicker materials like dimensional lumber. A 7-1/4″ blade can typically cut through 2x material at a 45-degree angle in one pass.
• Motor Type (Brushed vs. Brushless):
  • Brushed motors are the traditional, more affordable option. They have carbon brushes that make contact with the motor’s rotor, creating friction and heat.
  • Brushless motors are more efficient, last longer, and provide more power and run-time per charge. They are the standard for professional-grade tools.
• Battery and Run-Time: The battery’s amp-hour (Ah) rating determines its capacity and how long it can run on a single charge. Higher Ah batteries provide longer run-time but are also heavier. Some tools are sold “bare,” meaning you have to purchase the battery and charger separately. It’s often a good idea to stick to one brand’s battery platform if you have multiple tools to avoid having many different battery types and chargers.
