How to pick the right product

Shopping for the ideal circular saw requires patience and an eye for detail. You must keep in mind these important features to be able to purchase the ideal power saw that’s right for your workshop or worksite use.

  • Is a circular saw the ideal saw for your needs?

Do you really need a circular saw or do you need another type of saw? If you are looking for a saw to cut larger and thicker materials then you need a circular saw or table saw. If you need to cut smaller and delicate items, or you need a DIY saw then you must use a portable cutting saw instead.

  • Choose a power tool with a strong motor

You must use a tool with a high motor rating. The higher the motor rating, the more efficient it can cut through different materials with varying thicknesses. A circular saw with a 1500 watt motor will spin the blades faster to create high rotations per minute of the blades or RPM. Higher RPMs will be able to boost your tool’s overall performance.

  • All about blade capacity and cutting depth

Select a circular saw with a wide cutting capacity because a versatile saw can cut different materials for different projects and applications. The maximum cutting depth should be 0” which is how deep the saw can cut when it is not cutting a bevel. For cutting bevels and miters the saw must have a fully-adjustable base plate to make the most adjustments for every cut. This value should be around 45 to 90 degrees at least. These will improve the tool’s cutting range, versatility, and usability.

  • Choose circular saws that come with complete accessories

Circular saws are often sold in a set with accessories like blades, wrenches, guards and a bag. But aside from this, power saws can also be sold as bare tools. Buying bare tools could be cheaper compared to a complete set but in the end, you might pay more for accessories.
