Finding the Best Cordless Angle Grinder for Your Needs (Explained)
In the following paragraphs, you’ll find some of the most important key factors to consider while shopping for the ideal cordless angle grinder for a garage, a specific job, or any number of other applications:
Both brushed and brushless motors are produced by manufacturers for use in cordless angle grinders and other power tools.
It’s fair to say that brush motors have been around for longer, while brushless motors represent the cutting edge of electric propulsion technology.
To put it simply, brush motors are less efficient and more troublesome to maintain than their brushless counterparts. But many people favor them since they are less expensive than brushless motors.
Brushless motors are more low-maintenance than conventional ones, and they can have their output adjusted by sophisticated electronic controls on board.
These motors are more expensive than their brushed counterparts, but they are also more powerful and consume less energy.
How the user intends to make use of the motor will determine which one is best. Brushed motors are cost-effective for people who are fine with replacing the brushes every few years. Brushless models may be a good option for DIYers looking for the maximum power and efficiency possible.
The Power and Speed
The job calls for a powerful and quick cordless angle grinder. It is common practice to base power on the capacity of the battery.
Heavy-duty jobs like cutting metal stock or grinding welds require a model with more power than what you get from a 9-volt or 12-volt battery, and these models can deliver.
Additionally important is the rate of travel. The most flexible angle grinders have a speed range of 8,500 to 10,000 rpm. These velocities are ideal for grinding welds and cutting through metal.
The metal and grinding disc can be kept at a more comfortable temperature because of the various speeds available on some models.
Considering the high power requirements of cordless angle grinders, high-capacity batteries are a need.
Batteries with a higher amp-hour capacity are preferable, especially those that can run the grinder for many minutes without needing to be recharged. Some sets include a spare battery so that you can keep going even if one dies.
Those who have previously made an investment in a certain brand of the cordless power tool may have a surplus of batteries on hand. The same batteries may power a “bare tool” angle grinder, which they might want to purchase.
The cheaper cost of these grinders makes them a potentially excellent method to broaden one’s toolset without incurring a hefty financial commitment.
The Weight and Ergonomic Design
When the battery is removed, some cordless angle grinders weigh less than 5 pounds, making them easy to wield and maneuver for extended periods of time.
Over-molded rubber grips on angle grinders dampen vibrations and make for a more comfortable working experience.
Depending on the task at hand, the grinder’s handle can be positioned in a number of different ways to ensure the user’s comfort and safety.
The Disc Size
Discs with a diameter of 4.5 inches are standard on most cordless angle grinders since they are suitable for a wide range of jobs and can be spun rapidly.
In addition to being able to flatten welds and sand paint, they are also capable of cutting metal stock, angle iron, and sheet metal.
Discs up to 5 inches in diameter are no problem for some models. These devices’ speed and power output may be adjusted by sophisticated electrical technologies and often don’t need a brush.
The downside is that they usually cost more than devices with a 4.5-inch disc.
The Tool-free Adjustments
Since grinding frequently necessitates modifying one’s stance, grip, and/or rate of rotation, being able to make these changes rapidly is crucial to maintaining a high rate of output.
This is why many of today’s cordless angle grinders feature quick, easy adjustments that don’t require any tools.
The shield must be moved out of the way when the angle of the grinder is changed to prevent injury to the operator. Many models have little tabs that the user can flip open to enable this adjustment.
The ability to control the rate of rotation via a dial or button is a handy feature on many tools since it lets the operator be cautious while working and prevents the metal from becoming too hot.
It also increases the longevity of cutting and grinding wheels.
Additional Features and Accessories
The following are some additional features and accessories to think about, even though they aren’t covered in the aforementioned sections:
- Two-stage triggers, electronic brakes, and kickback brakes are some of the safety features that can be found in modern firearms.
- Some cordless angle grinders sell with accessory packages that include sanding discs, wire wheels, and grinding and cutting wheels.
- Users can purchase protective cases and bags to store and transport their cordless angle grinders between jobs.
The Bottom Line
Working on DIY projects or professional construction often requires the use of an angle grinder.
Unfortunately, traditional models are corded and can easily become tangled over the course of a project- reducing productivity to a snail’s pace. For this reason, having one readily available cordless angle grinder is enormously beneficial as it eliminates the need for constantly untangling cords.
The Makita XAG04Z 18V LXT cordless angle grinder, with its 8,500-rpm maximum speed and electronic feedback system, is the top choice for those in search of a versatile, fully-equipped cordless angle grinder. Cordless angle grinders are also more accessible in tight spaces and corners due to not having a cumbersome led attached to them.
Whether you’re a professional contractor or a passionate do-it-yourselfer, having the right tools is essential. A quality cordless angle grinder is an invaluable asset that no toolbox should be without.
That’s all for this guide, thanks for taking the time to read all the way to the end.
