DF64V Gen 1 Grinder — Overview & Highlights
The DF64V (sometimes referred to as Gen 1) is a single-dose, variable-speed coffee grinder that builds upon the original DF64 with several thoughtful upgrades:
Features a 300W brushless DC motor with adjustable speed (typically 600–1800 RPM), offering more control over particle size distribution and extraction profiles. Allows you to fine-tune speed depending on grind type—slower for uniformity or faster for increased fines when preferred.
2. Durable Burrs
Uses 64 mm flat burrs coated with Diamond-Like Carbon (DLC)—they’re more durable, longer-lasting (up to 10×), and reduce static adhesion.
3. Low-Retention Single-Dose Design
Designed to minimize ground retention. A rubber bellow and wooden lid allows you to push air through to empty the burr chamber, ensuring each grind is fresh. Retention is exceptionally low—often reported under 0.1 g.
4. Anti-Popcorn & De-Clumping Enhancements
Introduces an anti-popcorn disc to prevent beans from popping out during grinding, improving efficiency.
Upgraded declumper (de-clumping) mechanism, helping to prevent clogs and ensure smooth flow.
5. Build Quality & Aesthetics
Redesigned with a metal body, making it more durable and visually appealing compared to earlier vinyl-wrapped versions.
6. Ease of Cleaning & Maintenance
Equipped with a magnetic grounds chute and removable popcorning device, simplifying cleaning.
Removable chute + stepless collar = easier access for cleaning/burr swap

Grinding settings:
Turkish 5
espresso 10-25
Moka pot 35
fine filter 45 (aeropress or single V60)
Chemex 55
batch brew 65
French press 70
Cold brew 90
Lower RPM .... ... better for filter?
decrease fines and more uniform particle size distribution.
less heat
greater clarity and acidity ..... and less texture
Less static ...less clumping of grinds
Slower is not always better.
Recommended speeds for drip coffee - 600 to 1000 rpm
at settings of 45-90
-------------------
Higher RPM increase fines ... better for espresso
Less clarity but Adds body, texture and jucyness
More fines helps the portafilter build pressure
start at 1000+ RPM
Ideally Use about 1100 to 1400 for espresso
.... sweet spot is about 1200.... still some body but with a cleaner taste.
It seems that increasing the RPM will increase the body further (but decrease clarity) and should also increase the time it takes to pull the shot....
I think that extra fines are created when the burrs re-grind already ground & compacted beans that are stuck in the burr or from old grinder burrs that don't crush & cut the beans as well as they once did.
I have a cremaloop slow feeder which I think decreases the unevenness of the particles.
A lower RPM on your grinder might also achieve this. I like a lower RPM for filter but a higher for espresso..... that is, I like more fines for espresso.
--------------------
recommend hot dosing .. less chance of stalling the motor
(Note that some conical burr grinders can go slower ... some down to 100RPM)
A bigger burr can have 3 stages of cutting of beans which is difficult to implement in a smaller 64mm burr hence they usually have 2 stages(refer to image).
SSP has in fact made very amazing 64mm burrs as well but usually we see that increase in surface gives more room to designer which can potentially lead to more innovation & maybe a better burr.
They are uncoated and designed to be used for both espresso and filter.
I found that they are very middle of the road... with good body and texture & I feel they are OK for traditional dark and medium espresso. They are great for milk drinks.
However their clarity, sweetness & acidity is mixed up & intermingled to sit right in the middle.
They are not designed to highlight subtle characteristics like clarity that you would look for in "modern light roasted coffees."

The DF64V Gen 1 is actually one of the grinders most often modded with Korean SSP (Sung Sim Precision) burrs, since its 64 mm format is compatible with several SSP burr options.
Here’s a breakdown:
Modding the DF64V Gen 1 with SSP Burrs
1. Why Upgrade to SSP?
Consistency & Uniformity: SSP burrs are machined with tighter tolerances than stock DLC burrs.
You’ll see improved particle size distribution, especially at finer settings.
Flavor Clarity: Many users report enhanced clarity, sweetness, and separation of notes compared to stock burrs.
Longevity: Coatings (like Red Speed) extend burr life to 5,000–10,000+ lbs of
coffee vs. ~1,000–2,000 lbs for uncoated steel.
2. Popular SSP Burr Options for the DF64V
(All are 64 mm and compatible.)
Also Compatible With DF64, DF64P, DF64E, Mazzer Super Jolly and Mini-E, Anfim Caimano and CODY II, Lagom P64, Fellow Ode (2022 version or later), Ceado E5P, E6P, and E37J, Zerno Z-1, Wilfa Uniform, Gaggia MD64.
SSP Burr Type
A. SSP High Uniformity (HU)
Ideal Use : Espresso
Cup Profile: body, syrupy mouthfeel, more traditional style.
These are about $330 AUD
【Titanium Coating】Titanium Aluminum Carbon Nitride coating (red speed coated)
Inspired by Mahlkönig’s E65S burr.
B. SSP Multi-Purpose (MP)
Ideal Use: Espresso + Pour-over
Cup Profile: Cleaner, brighter, more clarity & fruit- forward, acidic.
These are about $380 AUD
Titanium Coating】Titanium Aluminum Carbon Nitride coating (red speed coated)
Unimodal.
C. SSP Cast Lab Sweet (Cast V2)
Ideal Use: Filter & Light-roast espresso
Cup Profile: Very high clarity, delicate, emphasizes acidity.
These are about $400AUD
This type of 64mm flat burr set designed to replicate the geometry of the Ditting 80mm Lab Sweet burrs, offering enhanced sweetness, clarity, and particle uniformity for filter coffee and espresso.
The "V2" refers to the earlier generation, often coated with "Silver Knight" (DLC) for durability. Made of Cast steel.
SSP Cast V2 are a middle ground between the SSP HU and SSP MPV2 and do fairly well for both espresso and pour over.
Ok for medium bodied espresso with flavour separation (esp milk based). It adds clarity and sweetness to pour over.
The Cast V2 is considered a good "middle ground" burr, balancing flavor separation with body, and was a predecessor to the Cast V3 burr set.
D. SSP Cast Sweet Lab V3 (CV3)
Ideal use : more espresso focused than the cast CV2
Cast with red speed coating.
$400 aud
The CV2 are a bit muddy and unbalanced in comparison
to the CV3 when it comes to espresso.
E: SSP Unimodal Brew (UMV1)
Ideal Use: Filter brewing (V60, Kalita, etc.)
Cup Profile: Maximum clarity, not recommended for espresso
$400 AUD
SSP MPV1 (Brew) with silver knight coating are the original brew burrs from SSP
Other options:
Mazzer 233M
