The catch
MiiCoffee DF64V Gen 3 Variable Speed Grinder
Variable speed is one more setting you have to record and understand.
Side by side
MiiCoffee DF64V Gen 3 vs TIMEMORE Sculptor 064S: Sharing a recipe means writing down the rpm on both
Quick verdict
If you will make use of its wider speed range or supported SSP burr options, choose the DF64V Gen 3. If its rotary grounds-clearing control suits your routine better, choose the Sculptor 064S. Variable speed and support for espresso and filter come with both. On either grinder, record rpm when you share recipes or switch beans.
Before you buy
Why, and what it costs you
Both have variable speed, but the extra range belongs to one
The Sculptor 064S already covers 800 to 1200 rpm, and the DF64V stretches that range to 1800 rpm. If you plan to stay between 800 and 1200, compare burr options and the clearing routine before treating speed as the deciding upgrade.
Where this comes from
Both speed ranges are listed in the manuals for the exact models. The comparison covers available settings only and makes no flavor, noise or throughput claim.
The catch
TIMEMORE Sculptor 064S
Its standard hopper holds around 30 g, which means refilling for larger filter batches.

- Why pick it
- You want to experiment beyond the 064S's 1200 rpm ceiling.

- The catch
- Variable speed is one more setting you have to record and understand.
TIMEMORE Sculptor 064S
- Why pick it
- Turning the rotary knocker after a dose is your preference.
- Your planned settings fall within the 800 to 1200 rpm range.
- The catch
- Its standard hopper holds around 30 g, which means refilling for larger filter batches.

What this page compares
DF64V Gen 3 vs Sculptor 064S on espresso, bean switching, batch size and cleanup, to show which daily routine makes the better buy.
Go with the DF64V Gen 3 for its documented 800 to 1800 rpm range and its optional SSP burr path. Go with the Sculptor 064S if turning a chute knocker appeals to you more than using bellows. Both suit espresso and filter, and each starts with a load limit of roughly 30 g.

Two people share espresso and filter recipes between them
Stepless grind adjustment and variable speed come with both. On either grinder, write down the rpm alongside the grind position.

I need speed settings over 1200 rpm
The DF64V goes up to 1800 rpm, while the 064S tops out at 1200. Extra range is a capability and not a guaranteed better result.

I change beans with every drink
As single-dose grinders, both let you weigh a different bean for each drink with no storage hopper to empty.

I'd like to try the optional SSP burrs
MiiCoffee lists SSP upgrades as optional for the DF64V. Do not assume that those burrs are an approved drop-in replacement for the Sculptor.

- TIMEMORE Sculptor 064S

Pumping bellows is not for me
A rotary knocker is how the Sculptor clears grounds. The DF64V uses bellows, which means a different action after grinding.

I grind a 36 g filter batch with a single fill
Both grinders have a stock capacity of approximately 30 g, which a 36 g batch exceeds, so plan on a refill.

In practice
Differences you will notice
Both have variable speed, but the extra range belongs to one
The Sculptor 064S already covers 800 to 1200 rpm, and the DF64V stretches that range to 1800 rpm. If you plan to stay between 800 and 1200, compare burr options and the clearing routine before treating speed as the deciding upgrade.
How we worked this out
Both speed ranges are listed in the manuals for the exact models. The comparison covers available settings only and makes no flavor, noise or throughput claim.
Clear the grounds with the cup still in place
The clockwise knocker from TIMEMORE and the declumper, bellows and chute routine of the DF64V Gen 3 both deliver the last released grounds into the current dose. Weigh the output after clearing, especially when you swap between regular coffee and decaf.
How we worked this out
Each manual describes its own clearing sequence. Input and output weights being equal cannot prove by themselves that no older grounds were swapped in.
One fill may not cover two drinks
Two 18 g doses come to 36 g, over either stock hopper rating.
How we worked this out
18 × 2 = 36 g. The Gen 3 hopper is rated at 30 g by MiiCoffee, while TIMEMORE gives it as around 30 g.
The 64 mm label alone does not decide the purchase
What you are choosing is a workflow and a burr design, and burr diameter does not increase.
How we worked this out
Each manufacturer specifies 64 mm flat burrs, yet the installed burr designs and the supported replacements are different.
It is easy to misread what auto-off does
Because the 064S stops after 60 seconds, it is neither a dose-weighing system nor an empty-bean system.
How we worked this out
According to the TIMEMORE FAQ, there is a 60-second shutoff and a physical stop button.

Spec by spec
Where they really differ
| Spec | MiiCoffee DF64V Gen 3 Variable Speed Grinder | TIMEMORE Sculptor 064S | In practice |
|---|---|---|---|
| Burr platform | 64 mm Red Titanium flat burrs | 64 mm espresso-capable flat burrs | The same diameter does not make the burr geometry identical or the taste a match. |
| Clearing the chute | Bellows and removable magnetic chute | Rotary knocker | Pick the action you will remember to do after each dose. |
| Stock bean load | 30 g | Around 30 g | Both advertised single loads are exceeded by a 36 g recipe. |
| Stopping | Physical on/off control | Button plus 60-second automatic shutoff | The timer on the Sculptor cannot tell when the beans have run out. |
| Basket transfer | Dosing-cup workflow | About 57 mm cup, intended for 58 mm baskets | For a 54 mm basket, find a suitable transfer method and do not assume the cup fits. |
Trade-offs
What each pick costs you
With MiiCoffee DF64V Gen 3 Variable Speed Grinder
- Fixed-speed grinders skip the complexity that a brushless variable-speed motor brings.
With TIMEMORE Sculptor 064S
- The catch cup in the box is meant for 58 mm baskets and does not fit 54 mm ones directly.
Decision guide
How to decide
Take the DF64V Gen 3 if you will use its wider speed range or supported SSP burr options. Take the Sculptor 064S if its rotary grounds-clearing control fits your routine better. Both have variable speed and support espresso and filter, and on either one you should record rpm when sharing recipes or switching beans.
Settle on the cleanup routine first
Going from espresso to decaf still means weighing the next dose and going back to its recorded grind and speed settings. According to the Gen 3 manual, there is a metal declumper, bellows and a chute-clearing sequence. The Sculptor uses a rotary knocker before you remove the cup. Compare the actions you will repeat every morning.
Control your speed experiments
When the speed range is your reason for buying the DF64V, hold the beans, dose and brew recipe fixed as you try a different setting. RPM is one more adjustment to manage and does not promise a better cup.
Look at the basket before you order
The Sculptor's catch cup is made for transferring into a 58 mm basket. If you own a common 54 mm espresso machine, plan on pouring or a suitable adapter instead of finding the mismatch on the first morning.
What this page can’t tell you
- Having variable speed in common does not mean equal retention, noise or coffee flavor. We added no head-to-head measurements.
- The specifications cover the listed version only. They say nothing about a taste ranking or about retention measured in your kitchen.
- Before you buy, check the exact model, the seller, the accessories included and, where it applies, the US electrical version.
