Can you grind coffee beans in a Nutribullet? Nutribullet itself advises against it in a standard blender cup. Its own blog says friction heat can cook off the oils that give coffee its flavor, and that hard beans dull the blade and strain the motor. It does sell two ways to grind coffee properly: a milling blade for the original nutribullet, and a coffee and spice grinder attachment for the Ultra models.

What Nutribullet Says
The maker’s own pages do not all say the same thing, so here is each one.
| Source | What it says |
|---|---|
| Nutribullet blog, “How to Grind Coffee Beans Without a Grinder” (June 2026) | Using a blender or food processor to grind coffee is not recommended, for two reasons: friction heat that can cook off the volatile oils and make the cup flat and bitter, and the wear that hard, abrasive beans cause to blades and the motor. It points to the Ultra Plus+ with its Coffee & Spice Grinder component. |
| Milling Blade product page | The milling blade, also called a flat blade, is “great at finely grinding nuts, seeds, grains and even coffee beans”, and the replacement blade is “only compatible with the original nutribullet”. |
| Coffee & Spice Grinder Attachment page | A dedicated attachment for freshly ground coffee and spices, compatible with the nutribullet Ultra, Ultra Plus and Ultra Plus 2-in-1. |
| 500, 600 & 900 Series user guide (2020) | Do not crush ice or other hard items without liquid, because prolonged use over time may dull or damage the blades. It also recommends replacing the extractor blade every 6 months. It does not mention coffee or the milling blade. |

What That Means for Your Nutribullet
- Original, 600 or 900 Series with the extractor blade (the standard blade in the cup): this is the blender-cup case the blog advises against, and the user guide says hard items should not be crushed without liquid. The old advice that you can fill a cup with beans and pulse is not backed by either.
- Original nutribullet with the milling blade: the product page says the flat blade grinds coffee beans, so this is the maker’s own accessory for it. The blog’s warnings about heat and wear still apply, so keep batches small and pulses short.
- Ultra, Ultra Plus and Ultra Plus 2-in-1: buy or use the Coffee & Spice Grinder attachment, which Nutribullet designed for whole beans.
- Any other Nutribullet or Magic Bullet: none of these pages covers it, so check your manual.
If You Use the Milling Blade Anyway
Nutribullet gives no timings or fill levels for coffee that I could find, so treat these as cautions rather than a recipe. The milling blade page asks for “proper pulsing technique”, and the blog’s heat warning is about continuous running, so pulse in short bursts instead of holding the cup down. Grind a small amount and let the cup rest between batches rather than running it continuously. Check the blade for dullness before each use, as the user guide advises.
The old version of this page gave grind times (3 to 5 seconds for coarse, 15 to 20 seconds for fine) and said to fill the cup three-quarters full. I removed them because no Nutribullet source gives those figures.
Matching the Grind to How You Brew
Nutribullet’s blog gives a simple guide: coarse for French press and cold brew, medium for drip, fine for pour-over, and super-fine for espresso or Turkish coffee. A blade cuts beans rather than crushing them between two surfaces, so expect a mix of fine powder and larger pieces. I could not find an independent measurement for a Nutribullet specifically, but a coarse brew like French press is the most forgiving of an uneven grind, and espresso is the least.
If grinding coffee is a regular habit, a dedicated grinder is the better tool; my best espresso grinder guide and manual vs electric grinder comparison cover the options. For brewing a coarse grind, see the best French press coffee maker and best coffee for French press guides.
Grinding Without a Grinder
If you have only whole beans and no grinder, Nutribullet’s blog lists three manual methods that work. A mortar and pestle gives the most control over grind size, from coarse to super-fine, and works in small batches. A rolling pin over beans in a sealed freezer bag or between sheets of parchment can reach a finer grind than people expect. A hammer is the last resort, best for coarse French press or cold brew, with light, steady taps.
How This Guide Was Put Together
This is a research-based guide built from Nutribullet’s own pages, linked above; I have not ground coffee in these machines myself. Three things I could not establish: any Nutribullet-published timings or fill level for coffee in the milling blade, which models the term “original nutribullet” covers beyond the 500, 600 and 900 Series, and how a Nutribullet grind compares with a burr grinder in an independent measurement. The user guide dates from 2020 and predates the blog post, so where they differ the blog is the more recent statement.
Frequently Asked Questions
Can you grind coffee beans in a Nutribullet?
Nutribullet advises against grinding coffee in a standard blender cup, citing heat and blade wear. It sells a milling blade for the original nutribullet, which its page says grinds coffee beans, and a dedicated grinder attachment for the Ultra models.
Which blade do I use to grind coffee in a Nutribullet?
Not the extractor blade. Nutribullet’s user guide says not to crush hard items without liquid, because it can dull or damage the blades. The milling (flat) blade is the accessory its page says grinds coffee, and it fits only the original nutribullet.
Will grinding coffee damage my Nutribullet?
Nutribullet says whole coffee beans are hard and abrasive, so regular grinding can dull blades and stress the motor, and that continuous running builds heat and pressure. Occasional small batches with the milling blade are the lower-risk case; the Ultra grinder attachment is built for it.
Which Nutribullet can grind coffee beans properly?
The Ultra, Ultra Plus and Ultra Plus 2-in-1, with the Coffee & Spice Grinder attachment, which Nutribullet designed for whole beans and spices. The Ultra Plus+ system ships with it. Other models have no maker-designed coffee option beyond the milling blade for the original.
How do I grind coffee beans without a grinder?
Nutribullet’s blog lists a mortar and pestle for the most control, a rolling pin over beans in a sealed freezer bag for a medium to coarse grind, and a hammer as a last resort for coarse French press or cold brew. Work in small batches.
If you are weighing a blender for more than coffee, see my Ninja BN801 review, and if a blender has started leaking at the base, here is why that happens.
