WPM KONOS — Single Dose 71mm Conical Burr Coffee Grinder
The WPM KONOS is WPM's answer to a simple question: what does a truly great single-dose grinder look like?
It starts with 71mm Italian-engineered stainless steel conical burrs, one of the largest in its class housed in a matte aluminium body that feels as good as it looks. Whether you pull espresso every morning or spend weekends exploring different origins, the WPM KONOS gives you the control to do it properly, every time.
Italian Burrs. Real Clarity in the Cup.
The 71mm conical burrs inside the WPM KONOS are crafted in Italy, and that matters more than it sounds. Larger burrs move slower, generate less heat, and produce a more uniform grind. The result is coffee that actually tastes like the bean you bought, the sweetness, the acidity, the clarity, the finish, all present and clear. It's the kind of difference you notice on your very first shot and wonder how you ground any other way.
1-Step Easy Cleaning, Cleaning Shouldn't Be a Project
The KONOS removes that no time to clean excuse entirely. The upper burr carrier comes out with one turn — no screws, no butterfly nuts, no tools, nothing to lose down. Rotate the bean hopper counter-clockwise, lift out the magnetic grounds outlet, and the whole burr chamber is open in front of you. A brush-out takes under a minute. Put it back, give it a light twist, and it locks into place and it is ready to go.
You Control the Speed. The KONOS Controls the Rest.
Most grinders give you one speed and call it a day. The KONOS gives you ten, ranging from 150 to 420 RPM, all shown live on the built-in display. Lower RPM means less friction heat and more delicate flavour preservation, which is exactly what light roasts need. Higher RPM clears the chute faster and handles dense dark roasts with ease.
There's also a Boost button — tap it and the grinder jumps straight to maximum RPM to clear any remaining grounds from the burr chamber. It sounds like a small detail. In practice, it's one of those features you end up using every single time.
One Grinder. Every Brew Method.
The KONOS uses true stepless grind adjustment, no clicks, no fixed steps, just a smooth dial that moves between the finest espresso grind and a coarse French Press setting. That kind of range is rare at this level.
Most single-dose grinders are built for one thing. The KONOS handles all of them well: espresso, pour-over, Aeropress, cold brew. Swap your beans, adjust the dial, and you're ready, no purging needed because the retention sits around 0.2g or less. For anyone who rotates through different origins or brew methods, that flexibility is genuinely worth paying for.

WPM KONOS, Every Shot Starts Here
Coffee doesn't taste this good by accident. It takes the right tools, a bit of patience, and a grinder that doesn't let you down.
The WPM KONOS fits into that morning rhythm the way a good piece of equipment should — quiet enough that it doesn't wake the house, precise enough that you notice when you change beans, and fast enough that it doesn't slow you down.
This is the part of your setup that makes everything else better. Whatever machine sits next to it, the WPM KONOS is what feeds it well.

Burrs
71mm Italian Burrs
the WPM KONOS has At 71mm, these conical burrs are among the largest available in a home grinder. Engineered in Italy, they run at lower speeds to reduce friction heat, produce a consistent particle size distribution, and preserve the full flavour spectrum of the bean — from delicate floral notes to deep, roasted body.
1-Step Cleaning
1-Step Easy Cleaning, just a twist
on the WPM KONOS the upper burr carrier removes with a single turn, no screwdriver, no tools, no loose parts. Rotate the hopper, lift out the magnetic grounds outlet, and the full burr chamber is open. A brush-out takes under a minute. Reassembly is as quick as disassembly, and the steel alignment bars ensure the burrs return to the exact same position every time.
Boost Button
Boost Button, leave no coffee behind
in the WPM KONOS after every grind, a small amount of coffee stays inside the burr chamber. One tap of the Boost button sends the motor instantly to maximum RPM, clearing those remaining grounds through the chute in seconds. The result is a more accurate dose, a cleaner chamber, and no stale leftovers mixing into the next brew.
Variable speed
Adjustable RPM with Live Display
on the WPM KONOS choose any speed between 150 and 420 RPM using the control panel, and watch the exact value update in real time on the built-in display. Lower RPM protects light roasts from heat damage. Higher RPM moves through dense dark roasts faster. You set it once per bean and the grinder remembers.
Stepless Dial
True Stepless Grind Adjustment
the WPM KONOS unlike stepped grinders that lock you into fixed settings, the KONOS uses a fully continuous dial that moves smoothly across the entire grind range — from ultra-fine Turkish and espresso all the way to coarse French Press. Micro-adjustments are easy and precise, which matters most when dialling in a new bean or a new recipe.
Anti-Static Chute
Ultra-Low Retention + Anti-Static
on the WPM KONOS has retention sits at approximately 0.2g, and 0.1g with Bellow, meaning almost everything you load in comes out as usable grounds — no waste, no flavour carryover between sessions. The built-in anti-static ionizer neutralises the charge that causes grounds to clump and stick to the chute, so your dose lands cleanly in the cup or portafilter every time.
Portafilter Fork
Portafilter-Ready Workflow
the WPM KONOS has integrated fork that holds a standard 58mm portafilter or dosing cup steady while the grinder runs, no hands needed, no mess. At the end of the grind cycle, the chute knocker taps the remaining grounds loose with a single clean strike, giving you a complete, accurate dose without any manual intervention between the grinder and your machine.
Matte Aluminium Body
Matte Aluminium Body, that give it and unpresented elegancy
on the WPM KONOS has the outer casing is machined from aluminium and finished in matte black. It keeps the grinder light enough to move but solid enough to stay put under use. The matte finish resists fingerprints and minor scratches, and the overall form is deliberately simple — no vents, no visible seams, nothing that ages badly or clashes with the rest of your setup.
WPM KONOS pretty to Look At. Precise Enough to Rely On
The KONOS doesn't shout for attention. The matte black aluminium body is simple, solid, and sits well on any counter — next to a machine, beside a scale, wherever you've built your setup. It's the kind of design that doesn't age badly.
But it's the feel of using it that people talk about. The stepless dial turns with a smooth resistance that makes fine adjustments easy. The RPM display gives you real feedback instead of guesswork. The knocker clears the chute with a satisfying click. When a grinder is this well-built, the whole process of making coffee shifts slightly, it stops feeling like prep and starts feeling like the point.

FAQs
Please read our FAQs page to find out more.
What makes the KONOS different from other single-dose grinders?
The KONOS uses 71mm Italian conical burrs, which is unusually large for a home grinder at this price. Combined with 1-Step cleaning so you always have the best taste of your beans, adjustable RPM, ultra-low retention, and built-in anti-static tech, it covers more ground — literally and technically — than most grinders in its class.
Is the KONOS good for espresso?
Yes, and it's built for a full rage from Espresso to French Press. The stepless grind adjustment lets you dial in very fine and make micro-adjustments easily — which matters a lot for espresso, where a fraction of a millimetre changes how the shot pulls.
Can I use it for filter coffee and pour-over too?
Absolutely. The KONOS grinds from fine espresso all the way to coarse French Press. If you switch between brew methods, the stepless dial makes it easy to move back and forth without committing to a fixed setting.
What does "single dose" mean, and why does it matter?
Single dose means you weigh out exactly how much coffee you want, load it in, and grind it fresh each time — nothing sits in a hopper. It keeps every cup as fresh as possible and makes it easy to switch between different beans without mixing flavours.
How much coffee does the KONOS retain after grinding?
Around 0.2g or less and 0.1g or less with Bellow, which is very low for an electric grinder. That means almost all of what you load in comes out as grounds — no waste, no stale leftovers from the previous session.
What is the Boost button for?
After grinding, a small amount of coffee can stay inside the burr chamber. The Boost button sends the motor to full speed for a moment, which flings those remaining grounds down and out. It keeps your dose accurate and your grinder clean between uses.
Is the KONOS quiet?
It's noticeably quiet for a grinder this powerful. At lower RPM settings (around 150 RPM), the grinding phase is short and the sound level is low. It's not silent, but it won't rattle the kitchen at 6am.
How hard is it to clean?
Very straightforward. The burr chamber opens without tools in one step, and a quick brush-out takes under a minute. Doing it once a week is enough for most home use.
Does it work with my portafilter?
The KONOS is designed for 58mm portafilters, which is the standard size for most prosumer and commercial espresso machines. It also comes with a 58mm dosing cup if you prefer to grind into a cup and transfer.
What is anti-static technology, and why does it help?
Static electricity makes coffee grounds stick together and cling to surfaces, which causes clumping and mess. The KONOS has built-in anti-static tech that reduces this significantly — your grounds come out loose, consistent, and easy to work with.
How does the RPM display work?
The display shows your current motor speed in real time as you adjust it. You can set it anywhere between 150 and 420 RPM using the control panel. Lower speeds suit light roasts and delicate flavour profiles; higher speeds work better for dark roasts and faster clearing.
What warranty does the KONOS come with?
Private buyers get a 2-year warranty. For business purchases, the warranty is 1 year. All orders through our store come with fully insured shipping.
How does the KONOS compare to the Niche Zero?
The Niche Zero is a well-loved 63mm conical grinder, typically priced around £549. The KONOS uses larger 71mm burrs and adds variable RPM, a live speed display, a Boost function, and built-in anti-static technology. For buyers who want more hands-on control over the grind, the KONOS offers a more complete feature set at a comparable price point.
Is this grinder worth it for a home setup?
If you already have a decent espresso machine — or you're planning to buy one — the grinder is often where the biggest upgrade in cup quality comes from. The KONOS sits at a level where it won't hold back a good machine, and it has enough range to grow with you as your brewing gets more precise.
