What to Look for While Buying the Cordless Angle Grinder

Here are some important things you should look into while buying battery-powered angle grinders;

Power Requirements

The first and foremost important thing you should consider while buying the battery angle grinders. Here, the thing to consider is the Watts number. The rule of thumb says the more Watts, the more powerful your grinder is. Likewise, another thing here that matters is the disc size as it can determine the capacity of your power tool. For a cordless grinder, I wouldn’t recommend you a large disc as it is absolutely complicated to handle. So, anything between 650 and 300 Watts is good for a battery-powered grinder.

Safety Mechanism

In addition, safety matters a lot whenever you are using a tricky power tool that involves cutting, grinding, and so on. Hence, there are multiple concerns related to security, such as slow starts or kickback, and even overheating. For these issues, you must consider a built-in lock mechanism and temperature regulator to prevent potential accidents at a reasonable price. For advanced safety, you can also go for restart and auto shut-off function, so you can maintain the optimal safety of the tool.

Battery Life

For a cordless angle grinder, what matters the most is its battery life as it is the only function that makes them distinct from traditional ones. Here, a standard battery would be between 5.2 to 6 mAh, so it can reduce the burden while maintaining the serving life of your grinder. On the whole, these are suitable for heavier and demanding tasks. Although there are some other affordable options like 3 Ah, I would advise you not to go for those as it is absolutely pointless.

Voltage and Speed

Similarly, voltage and speed matter a lot while you are on the hunt to find the right angle grinder. For an entry-level power tool, you can find grinders between 8 and 24V as it is suitable for a medium-range speed. When it comes to a battery-powered angle grinder, I would recommend you either go for 18 or 20V, so you can find the right balance between the speed and functionality.

In addition, when it comes to speed, a standard speed for entry-level grinders ranges from 5000 to 10,000 RPM. The important thing to consider here is that this speed is for the no-load setting. The rule of thumb is the higher the RPM range, the better it gets, and the minimum chances of injury. However, make sure it is compatible with the voltage and your skillset. Also, make sure the speed is consistent for the tool, so you don’t have other security-related concerns.

Disc Size

Another thing you should look for while buying the right cordless angle grinder is its disc size as it determines the capacity of your power tool. If you are a homeowner or own a workshop, you are good to go with at least a 4 or 5 inches wheel diameter, as this is easy to handle and offers you accuracy. For industrial or commercial applications, the minimum requirement is to have a 9 inches capacity. However, handling this disk would be an uphill task.

Now that you know all the basics of battery-operated angle grinders, you are good to go with making the right buying decision.

FAQs about Cordless Angle Grinders

All in all, always go for the one that is right for your skillset and the purpose you are going for.

Well, it primarily depends on what battery size you have and what are you using this for. For instance, a 5 or 6 mAh battery for heavy tasks can last you for approximately two hours. Although you can find affordable alternatives like 3 mAh, I would absolutely recommend refraining from those as they lack practicality and are pointless for grinding jobs.
