Covers specs, grinding for espresso and filter, handle, weight and who it suits." canonical: https://vettedten.com/kitchen/coffee-grinders/kingrinder-k6/ language: en-GB updated: 2026-11-11 score: 8.9 --- # KINGrinder K6 review > **Our verdict:** The best coffee grinder in 2026 is the KINGrinder K6. It tops our ranking with 8.9 out of 10. No. 1 of 10 in our [coffee grinders ranking](https://vettedten.com/kitchen/coffee-grinders/) · Updated November 2026 · [How we rank](https://vettedten.com/how-we-rank/) **8.9 out of 10** · Best Choice The KINGrinder K6 is an aluminium hand grinder with 48mm stainless steel burrs and an external dial. It suits people who brew filter or cafetière coffee by hand and want fine control, with espresso as an occasional extra. Why it's here: - External adjustment at 16 microns per click - 48mm stainless steel burr set - Aluminium body that comes apart by hand for cleaning - Can be driven by a drill for faster grinding Keep in mind: - Medium-roast espresso takes noticeable effort - About 630g, heavy for travel - Capacity is only 25 to 30g, and UK stock has been patchy [Check price on Amazon](https://www.amazon.co.uk/dp/B09WH9JKY1) ## Why the KINGrinder K6 scores 8.9 - How happy owners are: 1st of 10 - How many rated it: 7th of 10 - How new it is: 3rd of 10 ### Why No. 1 beats No. 2 The KINGrinder K6 (8.9) beats the Sage Smart Grinder Pro BCG820 (8.8): owners are about as happy with both, and it is the newer design. ## About the KINGrinder K6 The K6 is a manual grinder with a 48mm stainless steel burr set in an aluminium body. The brand's page lists a hopper capacity of 25g to 30g. Grind size is set with an external dial, and each click moves the setting by 16 microns. One review counts 240 clicks across four turns of the dial. It comes apart by hand, with no tools, and the brand says to clean it with a brush. The K6 weighs 630g, according to two independent reviews. That is solid for a hand grinder and more than a travel grinder needs. The K6 can also be driven by a drill. One reviewer describes a larger hex shaft and a special lid for this, and an o-ring swap between hand and drill use. They say the drill needs at least 15 Nm of torque, and their own household drill struggled. The same reviewer says the box holds a basic manual and a small bag with a spare o-ring and a clip, nothing more. The handle has a wooden knob. It is sold as a straight handle in some markets, and a bent one may still be available. ### Key specs - Burr: 48mm stainless steel - Body: Aluminium - Hopper capacity: 25g to 30g (brand's page) - Adjustment: External dial, 16 microns per click - Weight: 630g (two independent reviews) - Handle: Wooden knob, straight handle in some markets ## What owners report about the KINGrinder K6 We found little owner feedback for this exact model on pages we could open. Retailer review pages and the main forum threads were blocked or unavailable to us, so what follows comes from published reviews by people who used the K6, not from a wide set of owners. Reviewers like the solid, coated metal build and the repeatable dial. One reports about 40 seconds to grind 18g for espresso at a fine setting, and calls that quick for a hand grinder. Another says fine doses are slow and tiring by hand, and that an electric grinder suits daily espresso better. That matches the effort con on the page. On upkeep, one reviewer found that after taking the grinder apart the dial's zero point no longer lined up with the finest setting, and they had not found how to reset it. They also noted the cup has no rubber pad and may scratch, and that some users say the bearings can rust. Take those as things to watch, not as proven faults. ## Who the KINGrinder K6 suits The K6 suits someone who grinds by hand for two cups of filter, AeroPress or cafetière and wants a large burr and fine steps without paying for a premium hand grinder. It can reach espresso, so it works if you make a shot now and then and don't mind the effort. Look elsewhere if you pull espresso every day: the Sage Smart Grinder Pro BCG820 or the Eureka Mignon Specialita do the work for you. For travel, the Timemore Chestnut C2 Fold is lighter. If you want a hand grinder that is easier on the arm for espresso, the 1Zpresso JX is the one to compare. ## Questions about the KINGrinder K6 ### Is the KINGrinder K6 good for espresso? It can grind fine enough, but it takes effort. One reviewer found 18g took about 40 seconds at a fine setting, while another says daily espresso is better suited to an electric grinder. ### Does the KINGrinder K6 have a bent handle? It depends on the market. One reviewer says some markets now get a straight handle instead of the bent one, though a bent handle may still be available. The brand's page names the model as the straight handle version. ### Can you use a drill with the KINGrinder K6? Yes. One reviewer describes a larger hex shaft and a special lid for drill use, and says the drill needs at least 15 Nm of torque. Their own drill struggled. ### How much does the KINGrinder K6 weigh? 630g, according to two independent reviews. The brand's page does not list a weight. ### How much coffee does the KINGrinder K6 hold? 25g to 30g, according to the brand's page. That is enough for a two-cup pour-over or AeroPress batch in one load. ## All 10 coffee grinders, compared | No. | Product | Score | Badge | | ---: | --- | ---: | --- | | 1 | **KINGrinder K6** (this review) | 8.9 | Best Choice | | 2 | [Sage Smart Grinder Pro BCG820](https://vettedten.com/kitchen/coffee-grinders/sage-smart-grinder-pro-bcg820/) | 8.8 | Best Premium | | 3 | [Fellow Opus Conical Burr Grinder](https://vettedten.com/kitchen/coffee-grinders/fellow-opus/) | 8.8 | | | 4 | [Baratza Encore ZCG485](https://vettedten.com/kitchen/coffee-grinders/baratza-encore-zcg485/) | 8.8 | | | 5 | [Timemore Chestnut C2 Fold](https://vettedten.com/kitchen/coffee-grinders/timemore-chestnut-c2-fold/) | 8.8 | Value for Money | | 6 | [1Zpresso JX](https://vettedten.com/kitchen/coffee-grinders/1zpresso-jx/) | 8.7 | | | 7 | [Sage Dose Control Pro BCG600](https://vettedten.com/kitchen/coffee-grinders/sage-dose-control-pro-bcg600/) | 8.7 | | | 8 | [De'Longhi KG79](https://vettedten.com/kitchen/coffee-grinders/delonghi-kg79/) | 8.7 | Best Budget | | 9 | [Eureka Mignon Specialita](https://vettedten.com/kitchen/coffee-grinders/eureka-mignon-specialita/) | 8.4 | | | 10 | [Wilfa Svart Aroma CGWS-130B](https://vettedten.com/kitchen/coffee-grinders/wilfa-svart-aroma-cgws-130b/) | 8.3 | | ## How we score it Every score here comes from our ranking model; no editor sets the order. We haven't read the review sites for this guide yet, so for now it is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 17 models for this guide before settling on these ten. Brands can't pay to be included or to move up. We last checked these picks in November 2026.
