Having access to a quality burr coffee grinder can make all the difference when it comes to maximizing flavor from your favorite coffee beans. The SHARDOR CG9406-UL2 conical burr grinder aims to deliver excellent grind consistency and adjustability at a reasonable price point for home brewers. After testing this grinder extensively, I’m happy to report it achieves this goal incredibly well.

Below I’ll be going through all aspects of the SHARDOR CG9406-UL2 Conical Burr Coffee Grinder from unboxing to long-term performance. I evaluate the design, build quality, grind range, ease of use, noise levels, grind quality and value for money. Read on to see how this affordable conical burr grinder held up during testing.


The SHARDOR CG9406-UL2 Conical Burr Coffee Grinder is a conical burr coffee grinder with 35 grind settings. It has a 120V 200W motor with a rated capacity of grinding enough beans for 2-12 cups of coffee.

The all-black design looks sleek on the countertop. The bean hopper holds 8.46oz of whole beans, while the grounds bin can hold up to 4.58oz of ground coffee. An integrated grounds brush and scoop are included for easy transfer of grounds.

SHARDOR claims the grinder has “anti-static” technology to reduce mess and retain more grounds. The conical burrs themselves are made from durable stainless steel.

Key Features:

  • 35 macro grind settings from ultrafine to coarse
  • Durable stainless steel conical burrs
  • 8.46oz bean hopper capacity
  • 4.58oz grounds bin capacity
  • Anti-static technology reduces mess
  • Integrated grounds brush for easy cleaning
  • 120V 200W motor

Design and Build Quality

The SHARDOR CG9406-UL2 Conical Burr Coffee Grinder features an all-black plastic exterior housing the stainless steel conical burrs and motor. The design is relatively compact at 9.2 x 6.2 x 14.2 inches. The matte black finish looks modern and blends into most kitchens.

Despite the plastic housing, the overall build quality feels solid. All pieces fit together snugly without wiggle or vibration during grinding. Both the bean hopper and grounds catcher securely fasten into place.

The hopper, grounds bin, and upper burr all detach easily for cleaning and maintenance. SHARDOR thoughtfully includes the grounds brush stored on board to sweep out remaining grounds.

Anti-Static Technology Explained

The SHARDOR CG9406-UL2 is equipped with an advanced anti-static technology designed to minimize static buildup during grinding. Static electricity in coffee grinders can cause freshly ground coffee to cling to the grinder’s parts, making it difficult to transfer grounds cleanly and leading to messes. SHARDOR’s technology reduces static charge, allowing the grounds to fall smoothly into the bin and improving the overall cleanliness and efficiency of the grinding process. This feature is particularly beneficial in dry environments where static buildup can be more pronounced.

Grind Settings and Adjustability

A major highlight of this grinder is the wide range of grind sizes available. There are 35 macro grind settings clearly marked from the finest espresso grind to the coarsest French Press setting.

I tested the full spectrum of sizes from turkish fine up to french press coarse. The lowest settings consistently produced powdery, super fine grinds perfect for espresso. The mid-range settings were ideal for drip and pour over. And the largest 3 settings were very uniform in particle size for french press brewing.

The adjustment dial turns smoothly between settings with distinct clicks for each number. The macro settings are sufficiently far apart that you can precisely dial in a size for your preferred brew method.

The Science and History of Coffee Grinding

Coffee grinding technology has evolved significantly since its inception. The practice of grinding coffee beans to enhance flavor extraction dates back to the 15th century in the Arabian Peninsula, where coffee was first brewed. Initially, coffee was ground using simple mortar and pestle techniques, which evolved into more complex grinding mechanisms over the centuries.

Modern burr grinders, like the SHARDOR CG9406-UL2, employ precision-engineered conical or flat burrs to achieve a consistent grind size, crucial for optimizing the extraction of flavors during brewing. The science behind the grind size is that it directly affects the surface area exposed to water. A finer grind increases the surface area, allowing water to extract flavors more efficiently, which is perfect for methods like espresso. Conversely, a coarser grind decreases the surface area and slows down the extraction process, ideal for French press and cold brew, preventing over-extraction and bitterness.

The introduction of electric burr grinders in the 20th century marked a significant advancement in coffee grinding technology, offering coffee enthusiasts more control over the grind consistency and speed, thus revolutionizing home and commercial coffee brewing.

Grinding Performance

In daily use, the SHARDOR CG9406-UL2 Conical Burr Coffee Grinder performed very well grinding a variety of light, medium, and dark roast beans.

The conical burrs effortlessly chew through oily or sticky beans that can jam up inferior grinders. Hardness and density differences between bean varieties had little impact on grind consistency.

The integrated grounds bin reliably held the stated 4.58oz capacity when grinding for drip coffee. For espresso sizes, less could fit before needing emptied.

Grounds came out with minimal clumping and retained the flavors of the whole beans. Fines generation was average and acceptable for most home brewing.

How Grind Settings Influence Coffee Flavor

Understanding the impact of grind settings on coffee flavor is crucial for crafting the perfect cup of coffee. Finer grinds increase the surface area exposed to water, leading to a quicker extraction rate. This is ideal for espresso, where a rapid extraction yields a rich and bold flavor. Conversely, coarser grinds are perfect for methods like French press, where a slower extraction helps avoid over-extraction and bitterness. Adjusting the grind setting on your SHARDOR grinder allows you to fine-tune the balance between extraction time and flavor intensity, enabling you to customize your coffee experience to your taste preferences.

Brew Methods:

The SHARDOR CG9406-UL2 Conical Burr Coffee Grinder is versatile enough to grind coffee optimally for any popular home brewing device:

  • Espresso: The fine turkish and espresso settings produce superfine, powdery grinds perfect for espresso machines.

  • Drip Machine: Medium grind settings in the 10-20 range give consistent grinds for drip or auto-drip coffee makers.

  • Pour Over: Settings around 15-20 excel for pour over drippers like the V60.

  • French Press: The largest 3-5 settings give very uniform coarse grinds ideal for french press brewing.

No matter your preferred brew device, the SHARDOR can grind coffee optimally for full flavor extraction.

Safety, Ease of Use, and Maintenance

The SHARDOR CG9406-UL2 not only emphasizes user safety with features like automatic shutoff to prevent overheating and overload protection for the motor but also highlights ease of use with its intuitive controls. The grinder is designed for convenience, featuring clearly labeled buttons for grind size and cup selection, making the process straightforward even for novice users.

Maintaining the grinder is equally hassle-free. The removable components such as the hopper, burrs, and grounds bin facilitate easy cleaning, essential for preserving the machine’s functionality and ensuring the longevity of its parts. Regular maintenance and proper cleaning are vital as they prevent the build-up of old coffee residues, which can negatively impact both the flavor of the coffee and the efficiency of the grinder.

Noise Levels

The 200W motor produces a moderate amount of noise when grinding. It’s comparable or quieter than similar grinders with steel burrs. The all-plastic body seems to dampen vibrations well.

Standing right next to the grinder measured 71-74dB. The noise isn’t offensive, but enough I wouldn’t want to grind while someone sleeps nearby. It’s reasonably quiet for daytime use.


No products are perfect and the SHARDOR does have a few minor drawbacks:

  • The grind settings don’t have as much fine-tuning ability as stepless grinders in the $200+ range.

  • Grounds can stick to the plastic bin more than stainless steel catchers.

  • Louder than more expensive grinders with sound-dampening enclosures.

  • Small 8.8oz bean hopper. Not ideal for storing and grinding very large batches.

For the price, none of these negatives are dealbreakers in my opinion. Just limitations to be aware of.

Customer Feedback Analysis

The SHARDOR CG9406-UL2 Conical Burr Coffee Grinder has elicited a diverse range of opinions among its users, reflecting both its strengths and areas for improvement. Many users have commended the grinder for its consistent grind quality across various settings, highlighting its ability to produce even grinds that are crucial for optimal flavor extraction. The simplicity of use has been another point of praise, with the clear labeling of settings and one-touch operation making it particularly user-friendly. Furthermore, the grinder’s quiet operation relative to similar models has been appreciated by those who prefer a more serene morning coffee routine.

Despite these positives, some issues have been raised that suggest areas where the SHARDOR grinder could be enhanced. A notable concern involves the auto-timer function, which some users have found does not consistently shut off automatically as expected. This has raised questions about the reliability of this feature. Additionally, concerns about the durability of the plastic bean hopper have been voiced, with some users fearing that it may not withstand long-term use without showing signs of wear. The issue of messiness due to grounds escaping from the container has also been a common complaint, pointing to potential improvements in the design of the grounds bin seal.

Moreover, several users have reported inconsistencies in grind size when using the coarser settings intended for French press coffee, with an occasional production of overly fine grounds. This inconsistency could affect the quality of the brewed coffee, suggesting a need for further refinement of the grinder’s coarse setting mechanism. Lastly, there have been instances of motor failures reported within a few months of use, bringing the product’s long-term durability into question and underscoring the importance of a responsive and helpful customer service to address these reliability issues.

Overall, while the SHARDOR CG9406-UL2 Conical Burr Coffee Grinder offers significant value and performance for its price point, attention to the issues of mechanical reliability, material durability, and grind consistency could greatly enhance user satisfaction and the product’s market standing.
