Good to know
What is the best blade size for a circular saw?
7-1/4 inch is the most common size for general purpose cutting, offering a good balance of depth and portability. Smaller blades like 6-1/2 inch are lighter but cut shallower, while larger blades are for specialized tasks.
How do I know if a circular saw is powerful enough?
For most DIY and professional tasks, a 15-amp motor is sufficient for corded saws. Cordless saws with brushless motors and 18V or 20V batteries provide adequate power for most cuts. Check the RPM rating; higher RPM allows faster cutting through tougher materials.
Can I use a cordless circular saw for heavy framing work?
Yes, modern cordless saws can handle framing, but you need high-capacity batteries and possibly spares. Look for models with a brushless motor and a battery platform that is known for longevity. Many pros use cordless saws for all-day work, but expect to swap batteries frequently.
What safety features should I look for?
An electric brake is a valuable feature that stops the blade quickly. A retractable blade guard prevents accidental contact. Some saws have a lock-off button to prevent unintentional starts. Always wear safety glasses and use the saw with both hands.
How do I maintain my circular saw?
Keep the blade sharp and clean, and check the carbon brushes (on corded models) periodically. Clean dust from the vents and the motor housing. Lubricate moving parts if specified by the manufacturer. Store in a dry place to prevent rust.
What is the difference between a sidewinder and a worm drive saw?
Sidewinder saws have the motor positioned on the side, making them lighter and more compact. Worm drive saws have the motor oriented in line with the blade, providing more torque and durability, but they are heavier and often larger. Choose based on your preference for weight and power.
Can I change the blade on my circular saw?
Yes, blade changes are straightforward. Use the spindle lock to hold the blade still, then loosen the arbor nut with the provided wrench. Always unplug the saw or remove the battery before changing blades.
What is the advantage of a left-blade saw?
Left-blade saws (blade on the left side) allow right-handed users to see the cut line more clearly because the blade is on the side facing them. This can improve accuracy for right-handed users. Left-handed users may prefer right-blade saws for the same reason.
Are there circular saws with laser guides?
Some models include a laser guide to help line up cuts, but they can be inaccurate or drain battery on cordless saws. Many users find that a good quality blade and a clear line of sight are sufficient. If you want a laser, look for models with an adjustable guide.
The verdict
For most users replacing an old circular saw, the Makita 5007Mg is the best overall choice due to its power, durability, and precision. If you need cordless convenience, the Milwaukee 2732-20 is a top contender, but remember to budget for batteries. For budget-conscious DIYers, the CRAFTSMAN CMED500 gets the job done without breaking the bank.
