How to Choose a Battery-Powered Circular Saw – Buyer’s Guide

Battery-Powered Circular Saw

If you’re still not sure of what to look for in a cordless circular saw, read along to discover common features and learn more about their benefits.

Batteries

Circular saws are typically sold as bare tools, meaning the battery is not included. In such cases, the rechargeable batteries are sold separately.

Each saw brand produces its own rechargeable battery. While these power cells are rather expensive, they can usually be used interchangeably with tools from the same brand or line.

For example, an 18-volt Milwaukee drill battery can most likely be used with an 18-volt Milwaukee circular saw. As such, most people opt to expand their tool collection by investing in a specific brand.

For this reason alone, it is essential to thoroughly research a saw brand before making a purchase.

Motor

A good battery is of no use without a powerful motor to back it up. Since the blades in the circular saw rotate to make cuts, you need to pay close attention to its measurable torque and power rating.

Most cordless circular saw motors utilize a voltage that ranges from 18 to 24 volts, which is not bad for a battery-powered tool. Keep in mind that spiralizer gears tend to generate more rotational force in these models.

Blades

Circular Saw Blades

Saws are compatible with a variety of blade sizes. The most common circular blade diameter is 7 ¼ inches. However, blades that measure 6 inches or more can cut through standard 2-inch lumber with one pass.

Meanwhile, compact blades, or those that measure less than 5 inches, may require more than one pass to cut through standard lumber. Keep in mind that you can typically reduce the size of the blade you use with your saw.

Most saws are equipped with a standard multi-use blade. However, you can purchase blades for cutting wood, metal, and even concrete. If you intend to alternate blades frequently, you’ll want a saw that enables easy blade changes.

Bevel

Most circular saws have an adjustable footplate that can be used to produce angled, or beveled, cuts. Bevel capacities vary greatly depending on the model of saw.
Most saws have preset bevel stops that allow users to make quick and accurate adjustments. Typical bevel stops include 45, 53 and 90-degree angles

Build

While most circular saws follow a standard design, the position of the blade, motor, and handle vary greatly. For example, worm-drive saws have a blade positioned to the left and a motor positioned to the right.

Worm drives also have a handle that is positioned directly behind the motor casing. As such, these types of saws offer enhanced cut line visibility. However, they are not well-suited for left-handed users.

Alternatively, the motor and blade of sidewinder saws are positioned one after another. As such, they tend to be more compact.

Electric Brakes

Circular Saw Electric Brakes

Some circular saws have electric brakes. These mechanisms let you instantaneously stop the blade.

If a saw does not have an electric brake, you need to wait for it to manually slow down before changing any settings or replacing a blade.

Safety Features

Any time you’re looking at power tools, safety should be a number-one priority. Look for a saw that is made of lightweight materials, such as magnesium and steel, as these are easier to handle.

What’s more, make sure the saw you choose has a slip-resistant grip. All users should utilize safety glasses and hearing protection. Users should also take care to wear a dust mask to avoid inhaling dust and debris.

Ergonomics

It’s hard to distinguish the difference between saws without handling them. With that said, the grip and handle of saws vary greatly between manufacturers. A saw should provide an unobstructed view of the cut line.

It should also be easy to lift and handle for prolonged periods of time. What’s more, settings should be easy to access and offer quick and easy adjustments.

Extra Amenities

Once you find a saw that meets your standard requirements, you’ll want to factor in the value of any additional amenities. For example, some saws feature laser guides and/or built-in spotlights for enhanced visibility.

Some even have onboard wrenches for speedy blade changes. What’s more, some saws boast spindle locks that prevent blades from moving during changeovers.

Final Thoughts

The right circular may be the key to the success of your project. We recommend the Makita XSR01Z 18-volt X2 LXT Lithium-Ion 36V Brushless Cordless Rear Handle 7 1/4-inch Circular Saw to anyone looking for an amazing battery-powered circular saw.

Of course, the Milwaukee M18 2630-20 18-volt Lithium-ion 6 1/2-inch Cordless Circular Saw is also one of the highest-rated and most reliable cordless circular saws on the market.

Both of these saws are capable of deep accurate cuts, have an optional bevel, and are compatible with long-lasting batteries.
