Circular saws are an essential tool for any contractor or DIY enthusiast. They are versatile, and powerful, and can make cutting through wood, metal, and other materials a breeze. However, with so many options on the market, it can be difficult to know which one is right for you. In this guide, we will discuss the different types of circular saws available, the features you should look for, and the factors you should consider when making a purchase.
Types of circular saws
Worm drive saws
Worm drive saws have a powerful motor that is positioned in line with the blade, which provides more torque and cutting power. They are best suited for heavy-duty tasks and are typically used by professionals. They have narrower bodies to fit into small spaces and excellent balance, but they are generally heavier than other types.
Sidewinder saws
Sidewinder saws have a motor that is positioned perpendicular to the blade, which makes them more compact and lightweight. They are best suited for lighter tasks and are typically used by DIY enthusiasts. These saws are easy to control but are not as well balanced.
Cordless Saws
These saws are powered by rechargeable batteries, which eliminates the need for cords and gives you the freedom to move around the job site. They are best suited for light to medium-duty tasks and are increasingly popular among professionals and DIY enthusiasts.
Important features
Power
The power of a circular saw is measured in amps. The more amps, the more power your new saw will have. Look for a saw with at least a 15-amp motor for heavy-duty tasks and at least a 10-amp motor for light to medium-duty tasks.
Cordless saws have an amp hour rating that lets you know how long the battery will last. The more amp hours, the longer the battery should run. You will also see a volt rating, and basically, the more volts, the more power your cordless saw will have.
Blade Size
The size of the blade is measured in inches and ranges from 6.5 to 10.25 inches. A larger blade size will allow you to make larger cuts, but it will also make the saw heavier and more cumbersome to use. Cutting depth is dependent on blade size, so you want to be sure that you buy a saw that can cut deep enough for the wood you will be working with.
Blade types
Make sure you find a saw and saw blades to match the type of work you need to do. The main types of blades are:
- Cross cut: These are for cutting across the wood grain.
- Rip cut: These blades are designed to cut with the grain.
- Combination blades: These can cut in either direction of the grain.
- Specialty blades: You may need special blades for cutting other materials.
Bevel Capacity
Bevel capacity is the maximum angle at which the saw can tilt to make angled cuts. A higher bevel capacity will give you more flexibility, but it will also make the saw more expensive.
Dust Collection
Dust collection is an important feature to look for, as it will help to keep the job site clean and reduce the amount of dust that enters your lungs.
Safety Features
Look for a saw with safety features such as a lock-off switch, which prevents the saw from accidentally turning on.
Additional features
While these are not essential and you may not find them on every circular saw, these additional features can make your work much easier.
Ease of adjustment
As you cut, you will need to make adjustments to the saw, and you want these to be as effortless and intuitive as possible. Read reviews to see what others say about how easy the saw is to adjust. Youtube videos are also a good way to see the saw in action.
Saw blade changing
Look for a saw that makes changing blades easy. There are a variety of different ways that different manufacturers do this.
Laser Guide
A laser guide will help you make precise cuts by projecting a laser line onto the workpiece.
LED Light
An LED light will help you see the cut line in low light conditions.
Electric Brake
An electric brake will stop the blade from spinning immediately after you release the trigger, which can help to increase safety and speed up projects with many repeated cuts.
Ergonomic Handle
An ergonomic handle will make the saw more comfortable to hold and use for extended periods of time.
Adjustable Footplate
An adjustable footplate will allow you to make bevel cuts at different angles.
Conclusion
When buying a circular saw, it is important to consider the type of tasks you will be using it for, the features you need, and your budget. Take the time to research and compare different options, and choose the one that best fits your needs.
