But don’t just take my word for it. Let me break it down for you. The DCG418B has a whopping 11,000 RPM, making it the fastest grinder on the market. It also has safety features such as kickback brake and E-CLUTCH system, ensuring that you stay safe while using it. And, with a 20V MAX battery and Flexvolt technology, you can use it for longer without worrying about running out of power.

What is the difference between DCG413b vs DCG415b?

Now let’s take a closer look at the difference between the DCG413B and DCG415B angle grinders. Both of these models are quite expensive, but they do have some differences that may make one more suitable for your needs than the other.

Firstly, the DCG413B is the top-rated angle grinder. It has a decent RPM and battery life, making it worth the price for many users. On the other hand, the DCG415B is also quite expensive but doesn’t offer as much value compared to the DCG413B or DCG416B. Despite its decent RPM and battery life, it’s not recommended for those who are on a budget.

One key difference between the two is their blade diameter. The DCG413B has a smaller blade diameter of 4.5 inches, while the DCG415B has a larger blade diameter of 5 inches. This may not seem like much, but it can make a big difference in terms of the type of work you’re able to do with the grinder.

Ultimately, it’s up to you to decide which features are most important for your needs.

DCG412B vs DCG413B, Which one should you get?

You’re probably wondering which angle grinder to choose between the DCG412B and DCG413B, and the answer depends on your specific needs and budget.

Both grinders have their pros and cons, but ultimately, it comes down to what you plan on using it for.

If you’re on a tight budget and don’t need high RPM, the DCG412B might be the best option for you. It’s the cheapest of the two and has a unique design with a powerful motor. However, it does have the least RPM out of all the DEWALT angle grinders, so keep that in mind if you plan on using it for heavy-duty work.

On the other hand, if you need a grinder with good battery life and high RPM, the DCG413B is the way to go. It’s the top-rated DEWALT angle grinder with a score of 9.8 and is worth the extra money if you can afford it. It has good accuracy and can handle tough jobs with ease, making it a great investment for professionals or DIY enthusiasts who need a reliable tool.

The choice between the DCG412B and DCG413B comes down to what you need in an angle grinder. If you’re on a tight budget and don’t need high RPM, go for the DCG412B. However, if you need a grinder with good battery life and high RPM, investing in the DCG413B is definitely worth it.

At the end of the day, both grinders are great tools, and you can’t go wrong with either one.
