What To Consider Before Buying an Angle Grinder

Common Consideration When Buying Angle Grinders

1. Disk Size

An angle grinder uses a wheel or disc mechanism. We deem that is important to check or examine the size that an angle grinder has because it has an impact on the results. It will affect the coverage and the depth of the disc on the material upon contact.

The most common size we’ve encountered from our research is 4 ½ to 7.

We considered the size alongside other vital product features for our top 5 picks

2. Speed (RPM)

The speed of the disc is measured in rotation per minute or RPM. Our research will show that the speed runs from a wide range of 2,000 to 11,000 RPM. An equipment with higher RPM is likely to perform better. But, you need to remember that the speed should also suit your needs.

This also goes to show that the tool is equipped with variable power or speed, which you can set depending on your task. Therefore, you might want to look at the speed of the tool and compare it on your preference.

3.  Safety measures

An angle grinder installs different safety measures depending on each brand manufacturer. In our research, we examined what safety features are present in each tool. You can check the clutch, disc guard and lock and the guard among the other installations.

Some brands even allow right or left-hand adjustments to cater to different users.


How We Assessed and Evaluated These Angle Grinders

We love doing DIY projects at home from school related ones to home and living activities. However, we often use the most basic tools and less of the heavy duty equipment like that of an angle grinder.

We spent hours conducting research about the tool and have asked around from friends and family who have been working with this tool at home and as part of their profession since we have limited knowledge about angle grinder.

We have also spoken to two expert craftsmen which provided further assurance on our picks.

From here on, we then set criteria from which we chose the products. It has helped us sort through angle grinders with the best features that cater to varying needs of the users like yourself. We came up with a list of about 15 products and trimmed it down to 5.

It was challenging for us considering that aside from the huge number of choices, the majority of the products share the same features. However, we have managed to weigh the pros and cons of each product with a predetermined set of evaluation metrics. Hence, we think have come up with what we think is the best.


Our Top Picks

1. Makita 9564CV 4-1/2-Inch Angle Grinder (Editor’s Choice)

Click on the image to view the product on Amazon

Makita is one of the established and leading power tools manufacturer in the industry, which has been around for over 100 years in several countries. Under their long list of products is a powerful angle grinder tool.

The Makita 9564CV 4-1/2-Inch Angle Grinder is the most popular among craftsmen.

It has a wide range speed of 2,800 to 10,500 RPM. The changeable speed is quite expansive, which allows you to choose the desired RPM or enables you to choose the best speed for your work or application.

The disc or grinder size is 4 ½ inches, which depending on your preference or activity might be small. Our research shows that this measurement is the smallest since other has about 7 inches disc size. But, for home and personal use, 4 ½ inches may be enough to perform grinding tasks.

As for safety mechanisms, Makita tool is known for its clutch system, Super Joint System (SJS™) technology. This helps in protecting the motor as the grinding automatically stops when the disc binds. Thus, it prevents damage to both the tool and the user because it halts grinding when the disc encounters issues.

One concern we have regarding the tool is that the power button is a little difficult to use because it’s at time stubborn. The location of the button also is to an extent uncomfortable because you will need a certain position to turn it on or off.

What We Liked

  • Wide range speed
  • SJS™ clutch system

What We Didn’t Like

  • Uncomfortable power button design

2. Black & Decker BDEG400 6-Amp Angle Grinder, 4-1/2-Inch

Click on the image to view the product on Amazon

If you’re attuned to home appliance and tools, you may have heard of the Black & Decker brand, which is known for providing drilling tools sent to the moon. Since then the company has become a household name, many of the people we’ve talked to are familiar with their products.

The tool is equipped with a 4 ½ inch-sized grinder or disc size which you may find a bit smaller. However, for general use, the tool can be able to work as a grinding, rust removal and sharpening tool among many of its functions.

A downside that we found about the product is the limited application included in the set. You might need to individually purchase other applications to perform certain jobs.

All that is included in the tool is a wheel guard and a wrench. The wheel guard is necessary to protect you from flying debris from the material you’re working. Meanwhile, the wrench is useful when changing disc applications. We deem that these two are vital to ensure your safety and convenience when using the tool.

For added safety, the motor is encased in a metal housing to give it more durability over time. But, we found that despite the sturdy housing, there are issues of the motor stopping even when not intentionally turned off. Thus, you might need to check how it works on the initial use.

This product is also designed a movable side handle. It can give better control for the left-handed users and for various work positions.

What We Liked

  • Includes disc guard and wrench
  • Metal casing
  • Movable side handle

What We Didn’t Like

  • Issues with motor
  • Limited applications included

3. DEWALT DW840K 7-Inch Angle Grinder with Bag and Wheels (Second Runner-Up)

Click on the image to view the product on Amazon

From among the products on our list, the DEWALT DW840K 7-Inch Angle Grinder has the largest grinding size of 7 inches. This size may allow you to work on bigger projects that will require wider and deeper coverage.

But, unlike the other tools on the list, it has a lesser RPM of only 8,000 RMP. This RPM speed can already perform the basic tasks of an angle grinder. We think that this power is suited to the disc size with regard to safety.

The concern that we may find with the RPM power is that you will have lesser range compared to those reaching up to 11,000 RPM. Therefore, it might be helpful to consider the tasks or projects you are working on to determine the power you need.

We find the adjustable disc guard to be commendable because although it is movable, it does not easily budge. This is a vital feature because loose guards may cause debris or sparks to hit the user.

It also allows you to have more control over the tool with its adjustable handle positions. It specifically has two positions to cater to the comfort of the users. This is also helpful when you need to move around when working on a task.

The spindle lock of the tool allows a simple wrench operation to when you want to change the discs. It’s a good thing that the tool set includes a wrench to make it more convenient for you.

What We Liked

  • 7-inch grinder size
  • Adjustable disc guard
  • Adjustable handles

What We Didn’t Like

  • Only has 8,000 RPM

4. Flex L3410VRG 5-Inch Compact High Performance Variable Speed Grinder (First Runner-Up)

Click on the image to view the product on Amazon

This product deviates from the small 4-inch disc size as it is equipped with a 5-inch grinder. This can increase coverage and depth with your project, although minimal, the difference can still mean distinct result.

The feature that has caught our attention is the guard of the tool. An exclusive from the Flex L3410VRG 5-Inch Compact High Performance Variable Speed Grinder is the patented anti-twisting lock. This can help in ensuring that the guard is not loose especially when high speed is in the works. Thus, it can create better protection from particles and sparks.

As to its speed, it is one of the angle grinders on the list that has variable speed. You can choose from 3000 RPM to 11000 RPM. The variability of speed can help you in matching the speed and application you are using with the product (aside from grinder).

The product is installed with a mechanism which protects the motor with its quality shut-off brushes. Although we need to take extra care with our tools, there may be times that we are pushing it hard. Thus, the tool has this operation that can prevent total damage of the motor.

One observation we have of this product is that it is relatively expensive than the other angle grinders on our list. This can be an issue depending on your budget.

All these are encased in a lightweight tool of about 5 pounds. Thus, it may cause less hand strain.

What We Liked

  • 5-inch grinder size
  • Anti-twisting lock
  • Lightweight
  • Variable speed
  • 6-speed controller
  • Alloy frame body
  • Horn, reflector, and carrier frame

What We Didn’t Like

  • Comparatively expensive

5. PORTER-CABLE PC60TAG 6.0-Amp 4-1/2-Inch Angle Grinder

Click on the image to view the product on Amazon

PORTER-CABLE PC60TAG 6.0-Amp 4-1/2-Inch Angle Grinder is among the angle grinders with 4 ½ inch grinder or disc size. Although some may consider it as small, it can work for up to 11,000 RPM. The RPM capacity is among the highest from the product on the list.

These features are pack in a lightweight 5-pound angle grinder.

One thing that we find disadvantageous of having high RPM is that the product has no speed variation. This can lessen the control over the product and can also minimize the match of speed and application.

Users can have better control over the tool with its adjustable handles. However, unlike other angle grinders, the handle can be rotated. You don’t have to remove it to change positions. Simply, you can move it around, which may offer greater convenience and ease while doing tasks.

To guard you against the flying particles or sparks, the tool includes a disc guard. It can be adjusted based to accommodate your protection needs. Although it is not like the rotating handle, the disc guard can be removed with a single release. This can increase productivity while ensuring that you are protected in different angles.

Like DEWALT DW840K, this product uses a spindle lock to change wheels. Thus, it also includes a wrench. But, the spindle lock is quite loose causing loose spinning.

A hazard concern that we have about the product is that it heats up fast. This becomes an issue of comfort for some. While, while others may lose the confidence in the safety of the product.

What We Liked

  • 11,000 RPM
  • Rotational handle
  • Easy remove guard

What We Didn’t Like

  • Can heat up fast
  • No speed variation
