Why You Should Choose Your Angle Grinder Carefully

There are a lot of stores online that sells angle grinders. However, not all of them are made of excellent quality. Cheaper angle grinders have limited features and will break once if too much pressure is implied. That's one of the main reasons why you need to choose your grinder with caution.

Before buying, we suggest that you test your angle grinder. Check to see if the wheel cuts through stock and other objects in one pass. This ensures that your angle grinder will work and not fail when exposed to tough materials.


On What to Pay Attention When Choosing Your Angle Grinder

Type

Your angle grinders come with multiple wheels for different purposes. For home users, we suggest that you use grit discs for your grinding needs. While these discs are thinner, they cut at a relatively fast speed.

If you want an industrial level grinder for continued use, get a Diamond wheel grinder. Diamond wheel grinders are more expensive, but they have enough cutting power go through tough metals in one go. Consider the type of wheel of your grinder to ensure that you'll get the best angle grinder for your DIY jobs.

Here is a quick table showing the different wheel types and their desired method of operation.

Wheel Type

Explanation

Flapper

Helps Sharpen Shovels, Scrapers, Axes.

Buffing

Polishing, Adding wax before use

Tuck pointing

Removes mortar

Silicone Carbide

Sharpens metal tools, Sharpening, Cleans sheet metal

Aluminum Oxide

Friable material (Easy to damage substances),  Resists clogging and runs cooler, Woodworking

Cut off

Cutting and Polishing sheet metal

Power

There are three different ways your angle grinder can be powered. Below is a table explaining the different sources of power your angle grinder can use.

Power Source

Explanation

Electricity

Electricity is the most common energy source for angle grinders. The main benefit of more power powered tools is their portability. Some electric grinder models come with rechargeable Li-ion batteries that can be used if the power goes off.

Petrol

Consider using petrol angle grinders if you work at a small shop. Petrol engines drive and direct the cutting disc and help it pass through metals with ease. Make sure your grinder has an RPM of 3,000 or higher if you want a functional petrol angle grinder.

Compressed Air

Most high-end tools tend to use compressed air as a source. Air circulates from the interior to the machine and provides energy throughout the angle grinder. While it's the most expensive source out of the three, compressed air grinders offer the highest level of performance.

Variable Speed

The best angle grinders require this feature to work more efficiently. Variable speed allows you to adjust the disc's cutting speed.

Look for an angle grinder with variable speed to continue cutting metals at your desired settings. This feature lets you grind at a slower speed and is great for polishing metals.

Safety Clutch

Good angle grinders consist of a safety clutch for extra protection. The safety slip clutch protects you from kickback if your bind or wheel snags. Get a safety clutch if you want to increase the life span of your angle grinder.

Angle grinders with safety clutches are more likely to protect the user from an injury. Products without this feature tend to get stuck more often and take longer to complete your jobs more efficiently. If this is your first time buying an angle grinder, then this feature will enhance your overall performance.

Ergonomic Handle

Angle grinders are designed to fit safely in your hand. For example, anti-vibration handles keep your hand steady when the machine is operating. Get a grinder with this feature to improve your maneuverability and control over your angle grinder.

Ergonomic-Handle-On-a-Angle-Grinder

Moveable side handles allow the grinder to be used with one hand. This option is versatile and allows users to work in different positions. Find an angle grinder with both ergonomic features to remain safe in your work space.

Disc Size

Angle grinders come in various disc sizes from small to large. Common disc sizes range from 4 ½ inches, 5 inches, 7 inches, and 9 inches. For common applications, you'll want a disc size that's below 7 inches. You'll need a larger disc size if you want to make larger cut depths and finish your professional jobs on time.

Corded vs. Cordless Angle Grinder

You'll like using a corded angle grinder because they generate a lot of power. Professional workers tend to use corded grinders because they last longer and can be used throughout the day. If you need an angle grinder with high sustainability, then a corded grinder is your best bet.

Cordless angle grinders are more portable than corded grinders. However, their wheel size and quality won't add up to corded grinders. Because of this fact, cordless angle grinders are only useful for light and simple grinding.

The Verdict

If you want the best angle grinder for home use, the Dewalt DWE402K is the winner. It's a complete set of tools that optimize your performance when grinding metals. Ultimately, get this grinder if you want something that will work whenever you'll need it the most.

No matter what grinder you buy from this list, it will be a great asset to your work space. Buying an angle grinder is the best thing you can do if you want to grind and polish your metals.
