What is a Circular Saw?
A circular saw is an electric or power saw, which has a blade or a disc with rotary motion spinning around the arbor, to cut different types of materials. It has a handle with an on/off switch, the arbor holding the blade in place, as well as guards for the protection of the operator from the spinning blade. It has a variety of blades available for different kinds of cuts and, for different types of materials. Most circular saws are designed in a way which allows the user to adjust the depth and height of the cut, and many are also designed in a way where bevel cuts can be made. It can be handheld in which case the user can select a saw according to their dominant hand, or it can also be mounted on a table for more control and stability, and these could be some of the things to look for when buying a circular saw.
What you should be looking for When Purchasing a Circular Saw?
The use of the circular saw is being seen more and more nowadays, especially since it is one of the essential tools in the workshop of a DIYer after a drill machine. There are certain things which need to be kept in mind while purchasing a circular so that you’d know when it meets all your needs. A couple of standard requirements your new circular saw should meet, is a blade guard which covers the blade when it isn’t in use, a foot plate or shoe to steady the saw against the work-piece, depth adjustment for work-pieces with different thicknesses, and a bevel adjustment which allow the foot plate tilt in relation with the blade to make bevel cuts. Some other things to look for when buying a circular saw are:
- Style: Circular saws are available in two styles. Worm-drive saws, which are long or short, with the handle behind the blade. They tend to be on the heavier side with more torque tan sidewinders. The other type, the sidewinder, is the most recognizable to most people. The handle is higher than the blade and the blade is traditionally placed on the right side of the saw. They are cheaper and lighter than worm-drives and spin faster.
- Blade Size: Saws of the standard size of 7¼ inches can cut through any material which is more than 3-inches thick and also provides the most variety of blade choices for materials other than wood.
- Blade: Most of the newer saws come with carbide tipped all-purpose wood-cutting blade. There are other special purpose blades also available for cutting metal, wood, concrete, and tile. It all depends on your needs.
- Power: Circular saws’ powers are often expressed in amperage. Today, 15-amp saws are the most common.
- Ergonomics: The only way to ensure that the circular saw you want is perfect is to go ahead and check for yourself. It wouldn’t harm to hold a saw in your hands and check of the weight and the feel of the saw is perfect for you, and whether you’re comfortable with the blade’s visibility and the adjustment components.
