Questions worth asking
What is the difference between a sidewinder and a worm drive circular saw?
A sidewinder has the blade directly on the motor shaft, making it lighter and more compact. A worm drive uses a gearbox to transfer power, offering more torque and typically a longer blade on the left side. Worm drives are often preferred for heavy ripping, while sidewinders are easier to handle.
How many amps do I need in a corded circular saw?
For commercial use, a 15 amp motor is the standard. It provides enough power for cutting through thick lumber and repeated use. Some saws have 13 or 14 amps, but 15 amps ensures you have enough torque for demanding jobs.
Is a cordless circular saw powerful enough for commercial work?
Yes, modern cordless saws with brushless motors and high voltage batteries (like 60V) can match corded performance. They offer convenience and portability, but you may need multiple batteries for a full day of work. For heavy continuous cutting, a corded saw might be more reliable.
What blade size is best for general construction?
7-1/4 inch blades are the most common for construction because they offer a good balance of depth of cut and portability. They can cut through 2x lumber at a 45 degree angle and are widely available. Smaller saws use 6-1/2 inch blades, but they have less depth capacity.
How important is a dust blower on a circular saw?
A dust blower clears sawdust from the cut line, allowing you to see the blade path. This improves accuracy and reduces mistakes. Many commercial saws include a dust blower as a standard feature. If you cut a lot of material, it is very helpful.
What safety features should I look for in a circular saw?
An electric brake stops the blade quickly after releasing the trigger, reducing the risk of injury. A blade guard that retracts smoothly is also important. Some saws have a safety trigger to prevent accidental starts. Always wear appropriate personal protective equipment.
Can I use a circular saw to cut metal?
Yes, but you need a blade designed for metal, such as an abrasive or carbide tipped blade. Some saws have a variable speed trigger to control the speed for metal cutting. Always use the correct blade and follow the manufacturer’s recommendations for cutting metal.
How do I maintain my circular saw?
Keep the saw clean and free of sawdust. Regularly check the blade for dullness and replace it when needed. Lubricate moving parts per the manual. For corded saws, check the power cord for damage. For cordless, follow battery care guidelines.
What is the advantage of a magnesium shoe?
Magnesium is lighter and stronger than aluminum, reducing the overall weight of the saw without sacrificing durability. A magnesium shoe also resists bending, ensuring accurate cuts. Many high end saws use magnesium for the base and other components.
Are there circular saws with a left or right blade?
Yes, some saws have the blade on the left side and others on the right. This affects visibility and which hand you use. Worm drive saws typically have the blade on the left, which makes it easier to see the cut line for right handed users. Sidewinders often have the blade on the right.
The bottom line
For most commercial applications, the Makita 5007Mg offers the best combination of power, weight, and reliability. If you need a cordless option, the DEWALT DCS578B is your best bet. For heavy duty ripping, the Skilsaw worm drive is unmatched. Choose based on your specific needs, but any of these top saws will serve you well.
