SHARDOR CG301 Coffee Bean Grinder: 64mm Flat Burr Guide

SHARDOR CG301 Coffee Bean Grinder is the machine this guide follows, and the listing names it as a 64mm flat burr coffee grinder with 100 settings, anti-static features, in black. It sells for $169.99 and it is built around one large flat burr, a timed motor, and a short list of hardware details that are easy to check before you buy. The model number on the listing is CG301, which is the identifier to use when you compare sellers or look for the manual.

What this grinder puts on the counter

The coffee bean grinder runs a 260 W motor on 120 V and it is sold in black. The body measures 15.28 inches tall, 8.15 inches deep, and 5.2 inches wide, so the height matters more than the footprint when you plan a spot under a cabinet. The grinding chamber is all metal. A 64 mm flat burr sits inside it, the hopper feeds the burr from the top, and a stainless steel cup catches the grounds at the front. The control face is an LED display with a timer, not a dial with printed numbers. Everything the listing states is hardware you can see: burr size, chamber material, cup material, timer display, and voltage.

A 64 mm flat burr in a home grinder

Flat burrs cut beans between two flat discs, and the distance between the discs sets the particle size. A 64 mm disc is large for a home coffee bean grinder, and that size matters because a wider cutting edge spreads the work over more surface and keeps the beans moving through the gap. The all-metal chamber holds the burr alignment, and the burr is the part that decides whether the grind is even enough for a given brew method. Flat burrs are the common choice for espresso because the particle spread is narrow, and the same geometry still works for drip and pour over when you open the gap. No burr material or hardness rating is published, so there is no reason to repeat a number the seller never gives.

One hundred settings and what the steps change

This coffee bean grinder offers 100 grinding settings, and the range is meant to cover fine espresso through coarse French press and cold brew. Rather than jumping between named presets, changing the setting moves the gap between the burrs in small increments. That density of steps can be handy when a bean needs a small correction - a click or two is often enough. For larger changes, it's worth running the burrs empty first, then adding beans and adjusting in small steps. The listing gives no micron figure for the gap, so treating the display number as a relative position and tuning by taste is the most realistic approach.

Setting the timer for single, double, and continuous

Time is controlled from the LED display, accurate to 0.1 second. You can set times for a single dose, a double dose, or run continuously for a larger cup or bag. The timer controls how long the burr turns, not the weight of the dose, so finding the right seconds for a given dose is a matter of trial on your own scale with a new bean. Once set, it repeats consistently, and the 0.1-second steps make small nudges easy. The timer and the 100 settings serve different purposes - one adjusts particle size, the other adjusts how much coffee comes through.

Anti-static hardware and the stainless cup

Static is often what sends fines flying across the counter. This grinder's anti-static system, paired with its stainless steel cup, helps keep grounds from clinging. The metal cup gives them somewhere to land rather than sticking to plastic. It's not stated whether the stainless cup lifts out, so that's worth checking on arrival - if it does, moving it to the basket or portafilter is easier than tipping the whole machine. A stainless cup is also easier to rinse and dry than plastic, and less likely to hold onto old coffee smells. No specific anti-static voltage or coating is claimed in the listing, so it's fair to judge by the hardware itself.

The portafilter holder and the single-dose routine

A portafilter holder is built into the body, pointing toward a single-dose approach rather than grinding into a hopper for storage. Weighing beans, dropping them in, setting the time, and grinding straight into the cup or basket feels natural here. The silicone bellows on top can help push residual grounds out of the chamber with a press - useful when switching beans. The listing notes compatible single-dose hoppers are sold separately, so the stock hopper is the starting point. For those who prefer weighing by dose, this routine takes only a few seconds per cup and tends to keep older coffee from sitting in the chute.

A 20 g dose routine from hopper to basket

As one example, a 20 g dose can be weighed, added to the hopper, timed to taste, and ground into the cup or portafilter. The bellows can clear any last bits of grounds between doses when changing beans. It's just an example - your own dose may differ depending on bean and brew method.

Keeping things clean

Over time, a little residual coffee can build up in the chamber and chute. The removable parts are the magnetic discharge pipe, the upper burr, and the hopper. The grounds press helps clear what's left behind. The magnetic pipe comes off without tools, making a quick brush-out doable - unplug first, lift the hopper, remove the upper burr, take off the discharge pipe, and brush the chamber and burr with a dry brush. Water and burrs don't mix well here; a flat burr is a precision part, and moisture left in the gap can rust the steel and change the cut, so stick to dry cleaning. The stainless cup can be cleaned by hand. No cleaning tablet or branded brush is mentioned in the listing, so a dry brush and a cloth should be enough.

Footprint, height, and counter space

Height is the first thing to check - at 15.28 inches tall, the grinder needs clearance above the hopper if you plan to leave beans in it. At 8.15 inches deep and 5.2 inches wide, the footprint is modest. In practice, about 16 inches of clear space is needed to fit it, while a typical upper cabinet leaves around 18 inches, so there's usually about two inches of margin. Measure from your own counter to the bottom of the cabinet before committing, as that margin can shrink if a hopper lid or shelf lip intrudes. No weight is listed, but it's a counter appliance and best lifted with two hands when moving it.

What the grinder costs to run

The $169.99 price means the main running cost is beans. As an example, a 1 kg bag at $20 holds 1,000 g - at a 20 g dose, that's 50 doses for about $0.40 each. A cafe espresso at $5 to $6 runs $4.60 to $5.60 more per cup, so dividing $169.99 by that $4.60 to $5.60 per-cup difference puts the breakeven point between 30 and 37 cafe-priced cups if 20 g is your routine. A 250 g bag at $14 gives 12 doses at 20 g (about $1.17 each), so smaller bags raise the per-cup cost. These numbers don't include milk, electricity, or time, and 20 g is just a working example rather than something the listing states - plug in your own dose and bean price to get a realistic picture.

Voltage, motor, and safe operation

The motor is 260 W, rated for 120 V only. The listing is explicit: 220 V will damage the unit, and returns or refunds are not offered for damage caused by the wrong voltage. Stick to a 120 V outlet, skip travel converters, and unplug before removing the burr or discharge pipe. The 260 W motor is sized for home use rather than commercial volume - a continuous run can fill a bag in one pass, but it's built around a few timed doses a day. The 0.1-second timer is the precision tool for baskets and single doses; back-to-back batches for a cafe queue are outside what it's rated for. Keep the hopper lid on while grinding, and let the machine cool if grinding several doses back to back.

Where the grinder fits and where it does not

For a home espresso setup, drip brewer, pour over cone, or French press, the 100 settings cover a wide range and the portafilter holder fits a single-dose workflow. It's not a commercial grinder, not a 220 V appliance, and not a scale - a separate kitchen scale is what turns the timer into a repeatable dose. If you'd like to store beans in a hopper for a week, the stock hopper can do it, but the listing's note about single-dose hoppers points to the workflow it's really built around. The appeal is the burr and the timer, not features the listing doesn't claim.

The reference sheet

The facts worth keeping in one place are: model CG301, 64 mm flat burr, 100 grinding settings, 260 W, 120 V only, anti-static system, stainless steel cup, LED display with 0.1-second timer, single, double, and continuous modes, portafilter holder, silicone bellows, removable magnetic discharge pipe, removable upper burr and hopper, all-metal grinding chamber, black body, 15.28 inches tall, 8.15 inches deep, 5.2 inches wide, and a price of $169.99. Those are the claims the listing supports, and they are enough to compare the grinder with the other machines on the same shelf.

This grinder is a focused home unit: one large flat burr, a timer you can repeat, and a straightforward approach to keeping it clean. Check the voltage, measure the height, and do the bean math with your own dose, and the rest of the decision comes down to fit.
