1. Mr. Coffee Café Grind Automatic Burr Grinder

As an automatic burr grinder, adding Mr. Coffee’s Café Grind to your coffee corner is a good place to start.

This machine uses flat burrs to produce a uniform grind size, allowing you to extract the best possible flavor every time.

The stainless-steel body ensures long-lasting durability, while the 18 grind settings mean you can use it for different brewing needs.


Mr. Coffee is a well-known brand in the coffee industry.

It is among the oldest manufacturers of coffee makers, espresso machines, iced tea brewers, and, yes, coffee grinders.

The Mr. Coffee Café Grinder comes in a new version, featuring a modern stainless-steel finish that complements any kitchen.

The removable grind chamber and the bean hopper are made of durable plastic and are dishwasher-safe for effortless cleanup.

Plus, it also comes with a cleaning brush for your convenience.

Underneath the surface, is this automatic coffee grinder worth the price? Here are its best features to help you decide:

  • Flat Burr Plates

Burr grinders are highly preferred over blade grinders because they deliver a uniform grind and flavor consistency.

There are two types of burr grinders: conical and flat burrs. This Mr. Coffee unit is a type of flat burr grinder.

Generally, a flat burr grinder produces a remarkably uniform particle size of ground coffee.

That said, some say that it is like a smaller version of coffee mills suited for commercial uses.

Despite the low price, it features flat burrs that you will often see in higher-end models.

  • Automatic Grinding

This machine is fully automatic for convenient, hands-free grinding.

All you need to do is fill the hopper with whole beans, set the grinding level to your desired setting, and then turn on the machine to start processing the beans.

After grinding, the machine will automatically stop.

We like that the bean hopper is large enough to hold up to eight ounces of beans.

However, Mr. Coffee has a two- to 18-cup selector, which allows you to grind only the volume of fresh beans you need.

Meanwhile, the grinding chamber is removable for ease of cleaning and effortless ground coffee removal.

  • Adjustable Grind Settings

Do you plan to make different types of coffee drinks?

From espresso to cold brew and French press, you need a coffee grinder with adjustable burr settings.

The Mr. Coffee Café Grind can go from coarse to extremely fine coffee.

All in all, you’ll have 18 grind levels to choose from, so you’re likely to get your desired grind size for your morning or afternoon brew.

However, this machine might not cut if you’re after café-quality espresso.

While it has an “espresso setting,” it is designed for use with Mr. Coffee’s Steam Espresso machine.

So, instead, you will get grounds that are not quite fine enough to work with other espresso makers.

Thus, if you see yourself brewing a lot of espressos, this grinder isn’t what you need.


  • Flat burrs create a consistent and uniform grind
  • Stainless-steel construction
  • Great for bulk grinding
  • Adjustable grind settings


  • Not for espresso
  • Relatively loud

2. KRUPS Flat Burr Precision Grinder

KRUPS is a German manufacturer of coffee machines and has existed since 1846.

It makes different kinds of coffee grinders, from entry-level to commercial-type units.

The KRUPS Precision Grinder is an entry-level product that features a stylish stainless-steel front, a heavy-duty flat burr, and a one-touch operation.


The KRUPS Flat Burr Precision Grinder is another reliable machine that doesn’t break the bank.

Compared to the Mr. Coffee Café Grinder, you’ll only get 12 grind fineness settings. Nevertheless, it has intermediary settings for precise grinding.

As of writing, this model is KRUPS’ latest coffee grinder, offering improved performance and unmatched precision.

You’ll like that it’s very portable at 13.66 x 9.96 x 6.85 inches.

As you can imagine, it’s even smaller than a toaster, so it wouldn’t take much space on your kitchen counter.

  • 12-Grind Sizes

As mentioned, the KRUPS Precise Grinder features 12 grind adjustability options.

The dial on the front controls how long the machine will grind the coffee, as well as the number of cups you plan to make.

Each setting comes with micro-adjustments.

This way, you can produce the exact grind size ideal for your brewing method and extract the full flavor of your favorite coffee.

With the KRUPS Precise Grinder, you can process coffee beans for cold brew, French press, espresso, and more.

  • Impressive Capacity

Despite its sleek design, this grinder has a grinding chamber that can hold up to 32 cups of coffee grounds.

Meanwhile, the bean hopper can hold eight ounces of whole coffee beans.

  • Cup Quantity Selection

The KRUPS Precise Grinder has two- to 12-cup quantity selection settings.

These settings let you choose to grind just the exact volume of coffee grounds for you and a loved one or for a dozen people.

Once enough beans have been ground, the machine will automatically stop grinding, regardless of whether there are still beans in the hopper or not.

Nonetheless, you wouldn’t want to leave unused beans in the hopper because it isn’t airtight.

The same is true for the grounds chamber, so you’ll want to transfer the freshly ground coffee to another container.


  • Auto-stop function
  • Large capacity
  • Easy to clean
  • Burr grinder


  • Noisy
  • Static

3. Boly Electric Burr Coffee Grinder

This small but terrible machine features stainless-steel burrs, an impressive 18 grind settings, and an easy-to-clean design.

Even better, it’s priced under 100 bucks, so it’s perfect for those trying to stick to a budget.


The Boly Electric Burr Coffee Grinder is another excellent option if you’re looking for a cost-effective flat burr grinder.

The burrs themselves are made of stainless steel, so they are very durable and reliable.

Moreover, the machine has a safety lock, where it won’t grind until you securely place and attach the bean hopper into the burr system.

  • 18 Grind Size Settings

This burr coffee bean grinding machine boasts a total of 18 grind settings to meet your brewing needs.

You can choose from coarse to medium, fine, and extra-fine coffee, among others.

  • Adjustable Cup Quantity

This coffee grinder can process and produce enough coffee grounds for up to 12 cups at a time.

You can adjust the quantity from two to 12 to meet your different serving needs, whether brewing just for yourself or the entire family.

  • Compact Design

At first glance, it’s undeniable that this coffee grinder is smaller than its counterparts in the price range.

It measures only 10.98 x 8.15 x 5.31 inches, so it should be fine even if you have very limited counter space.


  • Compact design
  • Stainless steel flat burrs
  • 18 grinding sizes
  • Adjustable cups


  • Tend to overheat when run for over a minute
