The best flat burr coffee grinder for you depends on how you brew, how precisely you want to set the grind and how much coffee you grind at once. This guide covers six electric grinders whose listings state flat burrs: four with 64mm burrs and up to 100 settings, and two smaller mills that grind by cup count for drip and French press batches. The listings differ in settings, timers, hopper size, cleaning and warranty.
Every detail here comes from each product’s Amazon listing, and we did not test these grinders in person. Scores follow the four criteria in the How We Score section, and our Editorial Policy explains how we handle listing data.

We score each grinder out of 10 on four criteria, using only what its Amazon listing states. A clearly listed, strong feature earns 8 to 10, a partial one 6 to 7, a feature the listing does not mention 5, and one the listing shows as absent or contrary 2 to 4. The overall score is the weighted total.

The SHARDOR CG301 pairs a 64mm flat burr with 100 grind settings that cover espresso, moka, drip, pour-over, French press and cold brew. The listing says a click scale locks each setting, so the same grind repeats from day to day. A low-speed 260-watt motor drives the burrs, and the brand says the low speed limits heat and noise compared with blade grinders.
An LED timer works in 0.1-second steps with single, double and continuous modes, and a portafilter holder feeds grounds into your basket. An anti-static design, a silicone bellows and a stainless steel cup help keep grounds off the counter. The discharge pipe, upper burr and 250 g hopper come off without tools. It measures 8.15 by 5.2 by 15.28 inches and carries a 2-year manufacturer warranty. Score: grind range 9, burrs and grind quality 8, dosing and controls 9, capacity and care 9.

The Starseeker E64 uses 64mm stainless steel flat burrs with a titanium coating, which the brand says adds hardness and durability. It is the only pick with stepless adjustment, listed as 100 levels from fine espresso to coarse cold brew. A direct-drive motor spins at 1,800 rpm, and the listing says it grinds an 18 g espresso dose in about 7 seconds at around 68 decibels.

The Cuisinart DBM-8P1 is a flat burr mill with stainless steel burrs and an 18-position grind selector, from ultra-fine for espresso to extra-coarse for French press and cold brew. A slide dial picks 4 to 18 cups worth of grounds, and the grinder stops on its own when the cycle ends. A safety interlock keeps it from running unless it is assembled correctly.
The removable 8 oz hopper and a grounds chamber that holds up to 32 cups lift out, and the description says the parts are top-rack dishwasher safe. A cleaning brush, scoop and cord storage are included. The feature list says 500 watts while the spec table lists 140 watts, so we leave power aside.

How to Choose the Best Flat Burr Coffee Grinder for Your Brew Method
Match burr size to your brewing
Large 64mm flat burrs are common on grinders aimed at espresso and pour-over, while smaller mills often target drip and French press batches.
Count the settings you will use
Espresso needs small steps between fine settings, so 100 settings or stepless adjustment helps. Drip and French press work fine with fewer settings.
Decide how you dose
A timer or cup selector repeats the same amount each time, while single dose grinders expect you to weigh beans and grind them all at once.
Check hopper size and height
A large hopper holds several days of beans, but tall grinders can crowd the space under cabinets. Compare listed height with your counter.
Plan for cleaning
Removable burrs, magnetic chutes and brushes make cleaning easier. Some listings warn against water, so read the care notes before you buy.
