6 Circular Saw Tips Beginner DIYers Need To Know

Among the vast array of power tools out there, a circular saw can prove to be one of the most versatile items within a DIYer's arsenal. When used correctly, these power-packed tools can cleanly cut through a wide range of raw materials with ease. Their relatively compact size, handleability, and lower cost compared to the far larger miter saw make them ideal for those working in smaller spaces or who are looking for something more portable. 

However, if you think that using your circular saw is as straightforward as powering it up and slicing away, then think again. Like other power tools, there's quite a bit to know about circular saws if you want to get the most out of yours. Using one of these devices improperly not only leaves your project at risk of coming out poorly, but can result in injury to you in extreme situations. Just the notion of this possibility becoming a reality is enough to overwhelm some newcomers and subsequently them away from getting a circular saw for themselves. 

The good news is that by understanding the tool itself, using the right accessories, and employing some simple regular habits in your work sessions, you can master the circular saw and reap the benefits of all it has to offer you. To help you get off on the right foot, we've compiled a list of six handy tips that beginners — or even those simply looking to refresh themselves on the basics — should keep in mind as they use a circular saw. 

Before using a circular saw, you need to get your hands on one. To the uninitiated, these power tools all may look and function the same, but as any pro will tell you, there's more than meets the eye. Picking the right circular saw and blade depends entirely on your specific task, budget, and handling preferences, amongst other variables.

Most major tool brands carry their own circular saws, with a wide range of types to choose from. Among them are sidewinders (a common compact variety that has its motor placed on the side of the saw), worm drive saws (a heavier-duty option with the motor situated in the back), and hypoid saws (similar to worm drive saws but with more efficient gears and motor design). You also have the choice between corded or cordless saws. Cordless saws allow for more maneuverability and freedom, while corded options are better for performing lengthier tasks where you'll need power throughout. 

Perhaps the most important aspect to take note of when picking a circular saw is finding the right blade handling. Circular saws either come with the blade positioned on the right or on the left to allow users to work safely with their dominant hand. However, depending on your comfort level and specific work preferences, you may find that a blade handling type that corresponds with your less dominant hand is ideal. Take the time to assess your situation and get as much hands-on experience as possible before making a purchase to ensure you're making the best choice.

Your circular saw's blade is the key component to making sure that your job is done as swiftly and precisely as possible. Like the saws they're attached to, no two blades are the same and it's important you choose the right one before diving in on your project. 

There are a myriad of blade types to choose from, each with its own features and functions. The most common are combination blades, which are ideal for multipurpose work on wood and can perform a variety of cuts. Of course, there is a wide range of more specialized blades as well, such as crosscut, metal-cutting, ripping, and paneling, to name a few. Along with selecting a tool that can sufficiently cut through the material of your choosing, it's also important to know the teeth per inch (TPI) on your blade. Blades with a higher TPI will produce finer cuts, while those with less go through material more rapidly. In most cases, a combination blade with around 24 TPI will be sufficient for most general tasks. 

An oft-overlooked aspect of proper circular saw usage for beginners is blade depth, or how deep your blade protrudes from the bottom of the material's surface. Even if you have a fine specialty blade, having your blade extend too high or low can result in a messy cut while also increasing the chances of kickback and blade damage. As a general rule, you should have your blade extend between 1/8 to 1/4 inch from the bottom of your surface, depending on your blade type and specific task.

Part of what makes circular saws so attractive to DIYers is that their size makes them easier to handle and control than larger alternatives, allowing users to make a wide variety of cuts. But unless you're a seasoned pro with an eagle eye for precision, doing a freehand cut isn't a wise idea unless you enjoy making messy cuts and wasting material. Having the right accessories on hand can go a long way in making your jobs more efficient and preventing mistakes. 

Whether doing a standard straight cut on a shelf, a plunge cut for a window opening, or an angled cut for a decorative frame, accuracy and craftsmanship will be key to the success of your project, which is where additional tools and accessories can be of benefit. The triangular speed square is great due to its portability (some can even fit into your pocket), giving you a handy way to make quick marks or even be used as a straight edge alongside your saw. If you're seeking something longer and more durable, a piece of wood of your desired length can be clamped down to your surface and cut along the base. Masking or painter's tape can also be used for such a purpose, as they not only act as straight edges but can prevent splintering, helping maintain neatness.

While circular saws may seem intimidating for first-time users, they are nonetheless designed with plenty of safety features to prevent accidents, such as brakes, blade guards, and emergency stop switches. Nevertheless, it pays to be mindful of what these powerful tools are capable of and keep an eye out for signs of potentially dangerous issues. 

Among the most common hazards that can occur while using circular saws are kickbacks. This is an occurence when your saw blade is forcefully jolted back and launches either itself or the workpiece at the user. This dangerous phenomenon almost never happens out of the blue, usually coming about as a result of poor handling of the tool or weak securing of your surface. Thankfully, you can easily prevent kickbacks by taking regular steps to keep yourself and your tool safe.

Ensure that your saw is correctly set up before use by using sharp blades that are appropriate to your specific material. The surface you're working on should be thoroughly supported with no sections bending and always kept in place with clamps. In the case that your saw does experience a kickback, it will usually warn you by making strange noises and moving about in an ungainly manner beforehand. You'll quickly catch odd behaviors the more accustomed you become to regularly using your tool. As soon as you notice any unusual performance with your saw while in use, immediately lift your hand off the trigger and wait for it to power off entirely before removing it. 

There are further steps you can take in the way you interact with your tool and workspace around you to avoid accidents. While some tips seem to be common sense, others may not be as apparent, especially to beginners. However, even overly confident expert DIYers neglect these habits from time to time, which can result in some severe consequences. 

Don't even lay a finger on your circular saw without donning some safety gear. You don't want the debris and particles that fly about while your saw is in use to have access to your insides through your mouth, eyes, nose, or ears. Always keep these areas protected with safety glasses, dust masks, and ear muffs. The latter is also crucial to prevent hearing damage that can occur while working with loud machinery such as this over time. Likewise, you should always wear a sturdy pair of heavy-duty work gloves to keep your hands safe when removing blades and to have a better grip on the tool.

Avoid wearing loose clothing or jewelry that could get caught in the blade, and always keep long hair tied up while working. Be sure your workspace is clear of hazards that you may bump into or slip on prior to powering on your saw. The tool itself should never be forced when in use. When not in use, it should always be disconnected from its power source whether that be a battery or wall plug. 

How many years your circular saw stays functional depends as much on you as it does on your specific saw. Your tool will naturally experience wear and tear the more times it's used, but how you treat it will determine how quickly that usage takes its toll. To ensure it has as long a life as possible, it's important you pay attention to its condition and practice some regular maintenance.

Take the time to inspect the saw before and after every work session for any abnormalities. Remove particles or debris caught in the saw and wipe down the blade after each use to avoid buildup that could compromise its performance down the road. When not in use, keep both the tool (as well as its battery if it uses one) stored somewhere cool, dry, and secure that's free of moisture or excess humidity to prevent rust and similar damage. 

As you continue using your saw, you'll naturally grow accustomed to how it operates and more quickly pick up on signs of impairment. Slower than average performance, strange smells or noises, or lots of vibration are major red flags that should not be ignored. These could be indicators that you need a new blade, have a faulty power source, or have an internal issue that needs further attention.
