Best Weed Grinders of 2020

SLX Grinder

The SLX was already the best grinder around, and the V2.5 (Released early 2020) makes it even better. It retains all the positives of the original while improving the build quality. It has a smooth grinding action that does not require any effort, it grinds the herbs to a perfectly fluffy consistency, and it never needs to be cleaned. So, regardless of which kind of vaporizer you have, the SLX will be the perfect companion for it.

Zeus Bolt 2 Grinder

The Zeus Bolt 2 is an appealing choice for vapers that are looking for a low-cost grinder. It has a smooth grinding action and shreds down the herbs consistently. The scoop and the carrying bag are nice additional features that can be useful especially if you’re traveling. However, this grinder needs to be cleaned more often than other manual grinders.


The Tectonic9 is a manual grinder with an electronic dispensing action that makes it easy to use while keeping it portable-friendly. The grind consistency was good, and you can drop the herbs directly into your vaporizer. However, the additional complications involved with operating this grinder, plus the fact that it needs to be charged, means that it is not for everyone.

Space Case Grinder

Space Case grinders have a solid reputation because of their build quality and durability. They do an excellent job of grinding down dry herb, but you’ll need to clean out the grinder afterward, which can be a hassle. They’re also on the expensive side, and if you can afford it, then this grinder can serve you for years.

Santa Cruz Shredder

The Santa Cruz Shredder is one of the better grinders I’ve used because of how simple it is to use and how efficient the grind is. It’s pretty expensive, though, and it involves more cleaning than I like. Despite those problems, it’s easy to admire how well-engineered this grinder is when you use it. It turns super smooth, and the consistency is perfect for vaping.

Herb/Weed Grinders Buying Guide

What are Herb/Weed Grinders?

Herb grinders, aka weed grinders, do exactly as they say, they grind up the herb into a vaporizer-friendly consistency. This is necessary since large nugs won’t fit into most vaporizers and even if they could, they won’t get vaporized completely. Grinders can be either manual or electric, each of which has their pros and cons that we’ll get into later. However, I can tell you now that the grinder is the most important accessory to any vaporizer because you can’t use the vaporizer without it. So, now that you know that, let’s take a closer look at herb grinders.

Why Is It Important To Use a Good Grinder?

A grinder will break down the herb and give it a greater surface area so that it better fills the oven of the vaporizer. This allows the oven to evenly heat the herb, which improves the flavor and vapor production of the herb. Thoroughly ground herb also provides a better high because the terpenes and cannabinoids present in the herb are released more efficiently. Well ground herb also improves the airflow of the vaporizer and makes it easier to access the vapor because the heated air can pass through the ground-up herb more easily.

Manual VS Electric Grinders

Manual or electric is the main concern here since they are the two types of weed grinders from which to choose . Manual grinders require some elbow grease of course, but they are pretty easy to use and they have a few advantages:

  • You never have to worry if they are charged or not
  • They include their own receptacle to catch and distribute the ground herb
  • The good ones rarely, if ever, need cleaning
  • Most of them include kief catchers to collect some of the most potent parts of the herb
  • They are more portable-friendly than electric grinders

Electric grinders are not as popular as manual grinders since they don’t perform as many of the same functions as manual grinders do. Plus they are more high-maintenance since they need to be cleaned and charged regularly. Still, they do have a few advantages over manual grinders:

  • Can be easily used by anyone
  • It’s a little easier to calibrate the consistency of the grind

Overall, manual grinders are the way to go, even for newbie vapers. Electric grinders should only be used by people who have trouble using manual grinders.

The Best Weed, Marijuana, and Cannabis Herb Grinder 2019

What is a Herb Grinder?

A weed grinder is also referred to as cannabis/weed/marijuana grinder. Essentially, it is just a small device with teeth that are used to grind herb tobacco and other small plants. Depending on the design, herb grinders come with 1, 2 or three compartments. Additionally, they are made from different materials which include acrylic, metal and wood.

Before the herb grinder was designed an d introduced in the market, many people used scissors and some even their fingers to grind the herb into small chunks as they pleased. Needless to say, this was a tedious process which was also inefficient. What was even worse is that it left the smell of weed or the herb you were grinding on your hands. Currently, courtesy of improvement in technology and the availability of CNC machining, herb grinders were made and major improvements have been made as well. For any herb fan, the herb grinder is one stylish, functional and important tool they cannot afford to not have.

Now, over the years, the demand for herb grinders has increased. As a result, the supply of herb grinders has also skyrocketed. Why this is a great thing for the most part, it does make choosing the best herb grinder a difficult process. Note that the process is made difficult but not impossible. To choose the best herb grinder, there are some factors that you will need to pay attention to. These factors will help you to evaluate the quality of the herb grinder in question. Some of these factors include the shape as well as the number of the grinding teeth, the no. of pieces the herb grinder features, the material the grinder has been made from, the lid magnets and several other distinguishing features. In this piece, we go ahead and describe some of these features in details to give you a general idea of what these are.

Why Should You Use A Weed Grinder?

Once you start using a grinder, you’ll wonder how you’ve managed without one until now.

The first role of a grinder is to increase your cannabis’ surface area. This means you get more out of your bud, so over time it saves you money. Grinding your weed also allows it to be distributed more evenly over a joint, or in baking.

The best marijuana grinder will shred your weed fine enough to allow more heat to pass through the plant. By doing so, it releases more THC (Tetrahydrocannabinol) and CBD (Cannabidiol), as well as flavor and aroma.

The Difference Between 1, 2, and 3 Compartment Grinders

Here is how the compartments work:

1 compartment herb grinders (also called two piece grinders) have only one compartment where the herb is placed, ground, and retrieved. Because of that, the ground herb might be of inconsistent size. Also, retrieving the ground herb from the single compartment can be a little difficult since the teeth are in your way.

2 compartment herb grinders (also called three piece grinders) have the same grinding compartment as the 1 compartment grinder and small holes in the bottom of one compartment that leads to the second compartment. The holes allow only certain sized herbs to fall through and, because of that, you get more evenly ground herb. Since all the herbs are in the second compartment when finished, retrieving the herb is much easier than with a 1 compartment grinder.

3 compartment herb grinders (also called four piece grinders) have an additional compartment where there is a fine screen that separates it from the 2nd compartment. This 3rd compartment is for pollen or, if you are grinding marijuana, kief. Each of the herb grinders we selected on our best grinder list are 4-piece herb grinders.

Prices vary widely based on how many pieces an herb grinder has. Generally, four-piece weed grinders are more expensive than two or three-piece grinders, and for good reason. Four-piece grinders use more materials than other weed grinders and often include extra features like a filtering screen and pollen catcher chamber. However, we highly recommend buyers pick up a more expensive four-piece herb grinder because then you get the benefit of producing kief.

What Are The Different Types Of Grinders?

There are two main types of grinders available: manual and electric.

Manual grinders need a bit more elbow grease, as grinding is done through a rotation movement. Some grinders — called rotary grinders — even come with a handle to facilitate the process.

Traditional manual grinders usually come in two to four pieces, with varying numbers of chambers. These essentially catch the different parts of the buds. We’ll elaborate on multi-chamber grinders further down.

They might not seem as convenient as electric grinders. However, the manual ones often give you better control over the consistency.

There’s also an option for grinder cards. They can be a good option if you’re looking for the ultimate portable solution. Shaped just like a credit card, they’re small enough to fit in a wallet.

These might be the most convenient type of grinder, as they get started at the push of a button. They’re a great choice for those suffering from arthritis.

Most electric weed grinders don’t include a kief-catcher chamber. Despite their convenience, this can be a major drawback for many cannabis users.

There are many different electric weed grinding products available. They’re a good option if you need to grind a large amount of marijuana at once.

Because of the electric devices’ inability to filter the kief, manual grinders tend to be the preferred method for shredding cannabis.

Top 5 BEST Weed Grinders

The Zip Grinder is one of the largest grinders we’ve ever had the pleasure to use. The device is made out of aerospace grade aluminum and features 49 diamond shaped teeth, a 100-micron mesh screen, a clear top and side, and a pollen scraper tool.

We love the window, allowing you to see how much herb you’ve ground without having to open the chambers. Plus, you can really grind a lot of her in this thing so you rarely have to use it more than once a week unless you’re a pretty heavy smoker. The kief catching capabilities of this grinder are really great as well. You’ll find that you’ll get a pretty consistent grind from this device. Plus, if you want your weed to-go, you can take out the middle chamber and fit the entire grinder in your pocket.

However, it’s pretty easy to cross-thread this if you’re rushing. Also, the magnet is a bit weak.

Kozo is pretty new to the herb grinder scene, but they’ve made quite a splash in that time. One of the best selling brands on Amazon, Kozo has built a reputation as being one of the best herb grinder manufacturers out there.

The main benefit of their herb grinders is the indent around the edge of their grinders that allow you to get a better grip on the grinder for turning. This makes Kozo Grinders a good choice for those who use MMJ due of arthritis.

Another unique aspect of Kozo Grinders is the filtering screen that sits in the collection chamber, removing the need for threads on the screen. Made from two different pieces of aluminum, this could be an issue over time. However, due to the great reviews this grinder has received on Amazon I doubt it is a problem. Square teeth like those featured on the Kozo Grinder create a courser grinder, which will be good or bad based on preference.

Design Has Indents Around The Lid To Enhance Grip

Strong outer cover that can withstand pretty much and punishment

Benefits of Grinding Weed

There’s obviously a big difference between rolling your own cigarette or joint and using a manual roller. Sadly, the same can’t be said about grinding your weed vs. manually cutting it with scissors.

Using a grinder doesn’t make you seem incompetent. On the contrary, it makes it seem like you know what you’re doing. It’s not only a quality of life feature but more like a high-enhancing feature.

Here are the most important benefits of grinding instead of breaking up weed the old-fashioned way.

Wastes less weed

You can use less weed to get the same high

Grinders also serve as storage containers

Allows weed to maintain potency

Let’s you better pack and roll your joints

Your hands won’t smell or get sticky

Promotes even burning and consistent hits

You don’t lose as much THC

You won’t cut your fingers if you’re already high
