Bosch TSM6A013B Coffee Grinder Review: Is It Worth It?

Thanks for reading, I'm Sam. The Bosch TSM6A013B is a compact electric blade grinder. The grinder has a 180 W motor and a 75 g (2.6 oz) steel bowl. Bosch sells the grinder in black, white and red for budget buyers.

The Toddy cold brew we serve near the LIRR station shows me what blade grinders must do. The grinder suits filter coffee and French press. Filter coffee needs 15 to 20 seconds, and French press needs 8 to 10. The blade leaves an uneven grind, and the motor is loud. Owners praise the small size and low price. Espresso is out of reach.

The grinder runs on 220 to 240 volts. US buyers need a transformer, and the total reaches about $66. This review covers grind quality, cleaning, cost, the Krups GX204 rival and who should buy the Bosch TSM6A013B. The verdict here is mine, and the review has no sponsor.

What Is the Bosch TSM6A013B Coffee Grinder?

The Bosch TSM6A013B is a compact electric blade grinder for coffee beans, spices and nuts. The black plastic body holds a 180 W motor and a 75 g (2.6 oz) stainless steel bowl.

BSH Hausgeräte, based in Munich, makes Bosch-branded home appliances. Retailers list the grinder as the Bosch electric coffee grinder or, in German-speaking markets, the Kaffeemühle.

The last letter of the model code marks the color. The TSM6A013B is black. The TSM6A011W is the white version. The TSM6A014R is the red version. Some regions list the family as the MKM6003.

The bowl and blade are stainless steel. The body is plastic, per the Bosch spec sheet.

The body measures 17 x 9 x 9 cm (6.7 x 3.5 x 3.5 in). The grinder weighs about 0.6 kg (1.3 lb). A 100 cm (39 in) cord plugs into the wall.

Key Specs:

Spec	Value
Motor power	180 W
Bowl capacity	75 g (2.6 oz)
Grinding rate	150 g/min (5.3 oz/min)
Voltage	220-240 V, 50/60 Hz
Weight	0.6 kg (1.3 lb)

Bosch aims the grinder at budget buyers who want to leave pre-ground coffee behind. The grinder costs little and asks for no setup.

What Type of Grinder Is the Bosch TSM6A013B?

The Bosch TSM6A013B is a blade type of grinder, not a burr grinder. Bosch lists the type as chopping blades, with a two-blade stainless steel cutter.

A blade grinder is also called a chopper grinder. It chops beans like a tiny blender.

A burr grinder works differently. It crushes beans between two fixed surfaces. Burrs make a more uniform grind than blades do.

The Bosch has no grind size settings and only one speed. Nothing on the machine changes the size of the pieces except time. The user sets the fineness by holding the button down for a shorter or longer period.

How Does the Bosch TSM6A013B Work?

The Bosch TSM6A013B works by spinning a stainless steel blade that chops beans inside a sealed bowl. Bosch rates the fine grinding speed at 150 g per minute (5.3 oz per minute).

The user presses the switch in the lid and holds it down. A pulse function lets the user grind in short bursts for coarser results.

The motor sits in the base. The two-blade cutter sits at the bottom of the bowl. The lid holds the switch and a clear window.

Grinding Steps:

Add whole beans, up to 75 g (2.6 oz).
Press the lid down until the lid seats on the bowl.
Hold the switch for the target time, or tap the switch for pulses.
Release the switch and wait until the blade stops.
Open the lid and tip the grounds into the brewer.

A viewing window in the lid shows the grind level. Longer grinding gives a finer powder, so the user stops when the grounds look right.

How Long Should the Bosch TSM6A013B Run?

The Bosch TSM6A013B should run 15 to 20 seconds for filter coffee. Coarse grounds for a French press need 8 to 10 seconds in short pulses.

Fine grounds for a moka pot need 25 to 30 seconds of continuous grinding. The grind never reaches espresso fineness, however long the blade spins.

The three grind sizes match three brewing methods and three run times:

Coarse for French press: Run the grinder 8 to 10 seconds in short pulses.
Medium for filter coffee: Run the grinder 15 to 20 seconds.
Fine for moka pot: Run the grinder 25 to 30 seconds, continuously.

The brewing method decides which of these run times applies.

Runs should stay under 30 to 40 seconds at a time. Longer runs heat the beans and the motor. Heat buildup in the grounds can harm the aroma.

What Does the Bosch TSM6A013B Safety Switch Do?

The Bosch TSM6A013B safety switch cuts power unless the lid sits on the bowl and the switch is pressed down. The blades cannot spin with the lid open.

The switch also has a push button, and it must stay held for the whole grind. Releasing the button stops the blade at once. A stopped blade means the user decides exactly how long the grind runs.

How Well Does the Bosch TSM6A013B Grind?

The Bosch TSM6A013B grinds well enough for filter coffee and French press, but not for espresso. Blade grinders suit methods where the grind size need not be precise.

The 75 g (2.6 oz) bowl holds enough beans for a full pot of 8 to 10 cups. A full 75 g load takes about 30 seconds at the rated fine-grinding speed of 150 g per minute (5.3 oz per minute).

Uneven grounds fit some brewing methods better than others. Here is how the grinder handles each method:

French press: The grinder suits it well.
Drip coffee: The grinder suits it well.
Pour-over: It works, but the cup loses some clarity.
Moka pot: It works after a long run, though the powder stays uneven.
Turkish coffee: It is out of reach.

Espresso needs a very fine and even grind. A blade grinder cannot deliver that result, so a burr grinder is the better tool.

Does the Bosch TSM6A013B Grind Evenly?

No. The Bosch TSM6A013B does not grind evenly, leaving fine powder at the outside and coarser pieces near the center. A 10 second run showed a large gap in particle size.

Running the grinder longer does not close that gap. Fine dust and coarse chunks still sit side by side in the bowl.

Pulsing in short bursts and shaking the grinder between bursts moves beans back to the blade. The size gap narrows, but the grind stays uneven.

The uneven grind matters because water pulls flavor out of small and large pieces at different speeds. Fine dust gives up too much and turns bitter. Coarse chunks give up too little and taste watery. Both end up in one cup.

Is the Bosch TSM6A013B Loud?

Yes. The Bosch TSM6A013B is loud, like any blade grinder with a fast motor. A listing for the sibling MKM6003 gives a noise level of 75 dB.

Owners do not agree on how much the noise matters. Some call it acceptable for a kitchen appliance. Others call it a clear drawback.

Each run is short, 10 to 20 seconds, so the noise ends quickly. The noise stops as soon as the button is released.

What Do Bosch TSM6A013B Reviews Say?

Bosch TSM6A013B reviews say the grinder is good value but grinds unevenly. The Bosch South Africa page shows 4.5 out of 5 stars from 24 ratings.

Other retailers rate it in the same range. Yuppiechef shows 4.5 out of 5 from 37 reviews. Pepita shows 4.9 out of 5 from 16 reviews, mostly for the red version. Verkkokauppa shows about 4.7 out of 5.

Rating Sources:

Source	Rating	Reviews
Bosch South Africa	4.5 / 5	24
Yuppiechef	4.5 / 5	37
Pepita (mostly red version)	4.9 / 5	16

Across the first three retailers, the grinder averages about 4.6 out of 5 from 77 ratings. The scores mix the black, white and red versions. They describe the model as a whole and not one color.

Most written reviews are short and positive. They praise the grinder but give little detail. The detailed negative review includes a photo of a 10 second grind.

What Do Owners Like About the Bosch TSM6A013B?

Owners like the small size, low price and simple operation of the Bosch TSM6A013B. The grinder takes up little counter space.

The 75 g (2.6 oz) bowl saves repeat grinding for a pot. Owners also grind nuts, flax seeds and poppy seeds in it.

Buyers who brew filter coffee or grind spices rate the grinder highest. Buyers who expect espresso fineness or quiet use rate the grinder lowest.

Cleaning is easy for most owners. The price to performance ratio gets repeated praise.

Small footprint and tidy shape
Low price for a known brand
Grinds coffee, nuts and seeds
Simple one-button use

What Are the Bosch TSM6A013B Complaints?

The main Bosch TSM6A013B complaints are the uneven grind and the loud noise. Both come from the blade design.

Coffee powder collects under the blade. Removing the powder from there takes a small brush.

Voltage causes a third complaint. Listings in Canada can ship the European version, which is not built for North America.

How Do You Clean the Bosch TSM6A013B?

The Bosch TSM6A013B is cleaned by unplugging the unit and wiping the bowl and lid dry. The unplug step comes before every cleaning.

The motor housing must never go under water. A slightly damp cloth wipes the outside.

Coffee oils build up on the bowl after many grinds. These oils go rancid over time and sour the next batch. Regular cleaning protects the taste.

Grinding a small amount of dry rice binds the oils and odors. The rice flour is then thrown away.

The blades are sharp, so the grinder stays unplugged while a small brush lifts powder from under the blade.

All parts must dry fully before the grinder is put back together. Damp parts leave grounds stuck to the walls.

Cleaning Steps:

Unplug the grinder from the wall.
Wipe the bowl and lid with a dry brush or cloth.
Grind a spoon of dry rice to bind oils and odors.
Discard the rice flour and wipe the bowl again.
Dry every part before the lid goes back on.

Can the Bosch TSM6A013B Grind Spices?

Yes. The Bosch TSM6A013B can grind spices such as peppercorns, coriander seeds and cumin. The stainless steel blade also handles nuts and flax seeds.

Spices are strong, and they leave their flavor behind in the bowl. That leftover flavor can taint the next batch of coffee. Thorough cleaning after grinding keeps the coffee clean.

Poppy seeds also grind well in the Bosch. Short runs of about 20 seconds protect the motor.

How Much Does the Bosch TSM6A013B Cost?

The Bosch TSM6A013B costs between $28 and $56 in US dollars, depending on the seller. A comparison page lists the black model at $38.00 at a US retailer.

A US importer lists the grinder at $55.87.

The $38.00 listing is at Bloomingdale's. The Krups GX204 starts at $34.19. Both grinders sit in the same budget tier.

Cost Breakdown for a US Buyer:

Item	Price
Bosch TSM6A013B grinder	$38.00
Seven Star TC-300 transformer	$27.86
Total before adapter and shipping	$65.86

Warranty terms vary by seller. One shop lists 1 year, and another lists 24 months.

Does the Bosch TSM6A013B Work With US Outlets?

No. The Bosch TSM6A013B does not work with US outlets because the motor runs on 220 to 240 volts. The US grid supplies 120 volts.

A US importer labels the grinder 220 to 240 volts, not for the USA. Plugging the unit into a 120 volt outlet can damage the motor. The grinder is built for 50 or 60 Hz power. It ships with a Euro plug that does not fit a US outlet.

A step-up transformer raises 120 volts to the level the motor needs. The transformer should be rated above the 180 W draw. A plug adapter is also needed to connect the Euro plug.

The Seven Star TC-300 is a 300 W step-up transformer that lists at $27.86 at Battery Junction. The grinder costs $38.00. The total reaches $65.86 before a plug adapter and shipping.

How Does the Bosch TSM6A013B Compare With the Krups GX204?

The Bosch TSM6A013B and the Krups GX204 compare closely as blade grinders, with the Krups holding 10 g more. The Krups bowl holds 85 g (3 oz), and the Bosch bowl holds 75 g (2.6 oz).

Both grinders use a blade to chop the beans. The bowl size sets how much can be ground in one batch, so the Krups gives a slightly larger batch.

The Krups also has the stronger motor and the sturdier body. It uses a 200 W motor and a metal body. The Bosch uses a 180 W motor and a plastic body.

Walmart sells the GX204 in the US as the Krups Fast-Touch grinder. The Krups starts at $34.19, and the Bosch costs $38.00. The table shows the full comparison.

Spec	Bosch TSM6A013B	Krups GX204
Grinding system	Blade	Blade
Bowl capacity	75 g (2.6 oz)	85 g (3 oz)
Power	180 W	200 W
Body	Plastic	Metal
Price	$38.00	From $34.19

Is the Bosch TSM6A013B Worth It?

Yes. The Bosch TSM6A013B is worth it for buyers in 220 to 240 volt regions who brew filter coffee. The low price and simple use earn the grinder its good ratings.

Pros:

Low price for a known brand
Small size and one-button use
Grinds coffee, spices and nuts

Cons:

Uneven grind with no size settings
Loud motor
220 to 240 volt power only

The uneven grind and loud motor are the costs. Espresso drinkers should skip the grinder and buy a burr grinder.

US buyers face an extra hurdle. The voltage mismatch makes the grinder a poor pick at a 120 volt outlet. The same gap hits Canada, where listings can ship the European version.

Households that grind daily for several people also outgrow the 75 g bowl. A burr grinder is the step up. The Baratza Encore is an electric burr grinder with 40 grind settings. The Baratza Encore lists at $149.95 at Seattle Coffee Gear.

Who Should Buy the Bosch TSM6A013B?

Filter coffee and French press drinkers should buy the Bosch TSM6A013B. These methods forgive an uneven grind.

Home cooks who grind hard spices and nuts also benefit. The stainless steel blade handles both jobs.

Espresso drinkers do not fit the Bosch grinder. The brew needs a very fine and even grind that blades cannot make.
