Questions worth asking
What makes a circular saw commercial grade?
Commercial grade saws have stronger motors, durable construction, and better components. They are designed for continuous use and withstand job site conditions.
What is the difference between sidewinder and worm drive saws?
Sidewinder saws have the blade on the right and are lighter. Worm drive saws have the blade on the left and offer more torque. The choice depends on preference and cutting tasks.
Can I use a commercial saw for DIY projects?
Yes, but they may be heavier and more expensive than needed. However, they provide durability and performance that can be beneficial for frequent use.
What blade size is best for commercial cutting?
7-1/4 inch blades are standard and offer a good balance of cutting depth and portability. Larger blades cut deeper but are heavier.
How important is the motor amperage?
Higher amperage generally means more power. For commercial saws, 15 amps is common and provides enough power for most materials.
Are cordless saws as powerful as corded?
Modern brushless cordless saws can rival corded ones. Their power depends on the battery voltage and amp hour rating.
What safety features should I look for?
An electric brake stops the blade quickly. A blade guard protects against accidental contact. Some saws have a lock-off switch to prevent accidental start.
How do I maintain my circular saw?
Keep the saw clean and free of dust. Check the blade for dullness and replace it when needed. Lubricate moving parts occasionally. Store in a dry place.
The verdict
For most professionals, the Makita 5007Mg is the best commercial grade circular saw due to its perfect balance of power, weight, and durability. If you need a cordless option, the Milwaukee 2737-20 is a top choice, but be prepared to invest in batteries. For a budget pick, the Metabo HPT C7SB2 offers great value without sacrificing performance.
