Eureka Atom Pro vs 65

Are you trying to decide if you should choose the Eureka Atom Pro or the Eureka Atom 65? Then there’s no need to look further, because you’ve come across the right guide.

In this article, we’ll be putting the Eureka Atom Pro vs 65 in a head-to-head comparison. By the end, you can expect to learn the following:

  • What these grinders have in common.
  • The differences between them.
  • Information on their prices.
  • How to decide which one to choose.

With that being said, let’s dive right in.

Quick Summary

Eureka Atom Pro

Eureka Atom pro Profile

The Eureka Atom Pro brings “professional” to the Atom line in Eureka grinders. Its powerful 920-watt motor can breeze through continuous grinding, and its manual dosing system allows experts the flexibility to experiment. This is a great grinder for small businesses or high-tech homes.

Eureka Atom 65

This heavy-duty filter coffee grinder can support a wide variety of busy retail coffee shops from high-end locations to high-traffic cafes.


Burr Type

Eureka Atom Pro Burrs

Within both the Atom Pro and 65, you’ll find the same kinds of burrs: flat. This matters because the shape of the burrs has an impact on the flavor of the coffee you or your customers will be sipping.

In most grinders these days, burrs come in two shapes: conical or flat. Conical burrs are cone-shaped and produce bimodal particles, which means they grind coffee beans into different-sized particles.

Because of this, coffee that has been ground with conical burrs usually has a zesty and fruity flavor.

Alternatively, flat burrs produce uniform coffee particles. As a result, coffee ground from flat burrs has a richer, sweeter flavor.

Stepless Grind Adjustment

Controlling the texture of your grind is essential. Different types of coffee taste best when they’re ground to a particular setting, whether it’s fine or coarse.

The average grinder will be able to achieve this through stepless or stepped grind adjustment systems. The Atom Pro and 65 each have a stepless grind adjustment system.

To give you an idea of what means, it’s best to compare it to a stepped system. In a grinder with stepped grind adjustment, there’s usually notches or settings built into it to choose from.

This makes them remarkably easy for beginners to use, but there might be some gaps between settings.

In a stepless grind adjustment system, like with the Atom Pro and 65, you have a wheel or collar that can be turned to any setting available. This allows you to grind to a virtually limitless range of fineness settings.

Hands-Free Grinding

With some grinders, you need to stand in front of them the entire time they’re on, holding a portafilter or bag beneath the spout to catch the particles. That situation is far from ideal, as your or your employees’ time could be better spent attending to more important tasks.

Fortunately, the Atom Pro and 65 have portafilter holders. You can just set your portafilter in place and let the grinder hold it for you.

On-Demand Grinding

Coffee and espresso are best when they’re fresh. That’s because oxidation causes them to become stale rapidly after being ground.

Some grinders allow you to grind into large containers for later use, but this isn’t ideal if you’re not going to use those containers quickly. That’s why the Atom Pro’s and 65’s on-demand grinding design is better.

With either grinder, you’ll get as much as you need when you need it rather than grinding coffee in advance. On top of reducing waste, this ensures your drinks are as fresh as can be.



One immediately noticeable difference between these grinders is their size.

The Atom Pro measures at 18 inches tall, 7.2 inches wide, and 10.5 inches deep. It’s a modestly sized grinder that doesn’t take up too much space.

In comparison, the Atom 65 measures at 21 inches tall, 6 inches wide, and 9 inches deep. If you have low-hanging cabinets, it won’t fit under them as easily. However, it can squeeze between other appliances because of its thinner profile.

Hopper Size

The hopper stores your coffee beans prior to being ground. A larger hopper equates to being able to grind for longer amounts of time before you need to add more beans.

Atop the Atom Pro, you’ll discover a hopper that can hold approximately a pound of beans. This isn’t a large capacity by any means, but it will make it possible for you to grind for awhile between refills.

The hopper on the Atom 65 is a little over twice the size, and can hold about two and a half pounds of beans. A greater capacity does mean the grinder itself is larger, though, which is why its height might not be suitable for spaces with cabinets above them.

Burr Size

One of the greatest risks you take with grinding coffee beans is burning them. The risk generally increases the longer you grind, because your grinder grows hotter with extended use.

That’s where the burr sizes comes in. Larger burrs can grind more coffee without needing to turn as much because of their significant surface area. In other words, the risk of burning beans is lower the bigger the burrs are.

The difference between the Atom Pro and 65 in this regard is slight. At 75 mm, the Atom Pro’s burrs are a bit bigger than the 65’s 65 mm burrs.

Motor Power

No one likes having to wait in line longer for their drinks. Similarly, you probably don’t like waiting long around your counter at home.

Higher power motors help shorten wait times when it comes to grinding fresh coffee. The higher the wattage, the faster your grinder can go.

In terms of motor power, the Atom Pro is the clear winner. It has a strong 920-watt motor that won’t break a sweat as it breezes through your grinding.

To put that into perspective, the Atom 65’s motor is at about half that power with 480 watts. It’s a perfectly fine grinder, but it’s not as powerful as the Pro.

Atom Pro Cooling Fan

Earlier, we mentioned that continuous grinding puts your coffee at risk of being burnt. Large burrs can help with this, but the best defense against burns is a tough cooling system.

The Atom Pro has exactly that with its cooling fan. No matter how long you operate it, the Pro can keep itself nice and cool.

In the end, that leads to a better-tasting drink. You won’t notice any burnt notes in the flavor here.

Atom 65 Programmable Dosing

If you’re a beginner, learning exactly how long to grind to make one dose of espresso or coffee is difficult. It’s easy to get too much or too little if you’re not cautious.

The Eureka Atom 65 simplifies the process by having programmable dosing. You can input the times for both single and double shots, so that you don’t need to worry about timing in the future.

And if you want the flexibility of timing yourself, there’s a manual button built into the center. You get the best of both worlds when it comes to manual and timed dosing with the Atom 65.

Atom Pro Magnetic Hook

This is a nifty feature that makes adjusting the portafilter holder easy. Many other grinders will have protafilters with prongs that swing out or can be moved to accommodate different sizes.

With the Atom Pro, adjusting the height of the holder is as easy is picking it off and putting it where you want it to be. It’s magnetic, and can stick to the front panel at any height.

Atom 65 Color Choices

Looks matter, even when you’re purchasing an appliance. If you’ve got a particular color scheme in your home, you’ll want everything to match – even your coffee grinder.

The Eureka Atom 65 comes in two different color options. You can get it in a dignified black or sleek chrome – the choice is yours.

Atom Pro Blow-Up Hopper

Grind retention occurs when particles get left behind in your grinder after use. It can be a hassle to deal with, because these leftover particles get stale and then get mixed into future drinks.

The Atom Pro factored this into its design with a blow-up hopper. That means the hopper functions like a pump.

Simply press down on it, and it will blow air through the inside of the grinder, helping you quickly clean out any straggling coffee grounds.

Pricing Information

Which One Should You Choose?

All the features in the world don’t necessarily help you decide how to choose a grinder, unless you understand how they all apply to you. We’ll examine some of the highlighted features of the Atom Pro and Atom 65 so you can see how to choose one or the other.

The Atom 65 has features that make it a wonderful choice for home baristas in need of a personal upgrade. Its programmable dosing is a gift to beginners, and its anti-clump system will help keep your countertops sparkling.

Furthermore, it has a silent grinding design that’s perfect for those who don’t want to wake up their home every time they’re craving a fresh cup.

At a more modest price than the Pro, the Atom 65 may also be more feasible for home baristas.

The Eureka Atom Pro has the qualities a business needs. With larger burrs and a more powerful motor, it can go through beans more quickly than the 65.

On top of that, its cooling fan makes it possible for you to grind non-stop when necessary without singing your beans. This isn’t likely to be a problem in a home, as home baristas are probably not grinding as much as small businesses.

Here’s the bottom line:

While both are excellent grinders, the Atom Pro is better-suited to a commercial environment or home espresso enthusiasts with a larger budget.

The Atom 65 is a wonderful home espresso grinder for those who need something a bit more economical.
