A high-quality weed grinder can make a big difference in your smoking experience. When all your weed has a smooth grind, your bowls and joints hit better and burn evenly. A grinder is an excellent investment because a great weed grinder will last you for years if you take care of it.

Although a high-quality grinder is not the first accessory smokers usually buy, it is crucial to get one after starting your pipe collections. This post will help you decide on the best weed grinder for you.

Why Use a Grinder?

A grinder saves you from having to use your fingers to break up your weed. When you break up weed with your fingers, you lose pieces, kief sticks to your hands, and the weed is difficult to transfer to your pipe.

Using a grinder saves you time. It also more consistently turns your nugs into ground weed that you can pack into a bowl or roll into a blunt. A quality grinder is easy to turn and has strong teeth made to quickly and effortlessly chop up your cannabis.

We have the most popular weed grinders in multiple variations with mesh screens, viewing windows, kief catchers, and big grinding chambers. We only carry metal grinders with sharp teeth.

Best Overall Weed Grinder:

Cali Crusher OG 2.5 inch 4-Piece Grinder

The Cali Crusher OG is precisely what you want in a sleek, anodized aluminum grinder. The colors are shiny and metallic, and the spin is perfect. From one of the most popular and best grinder brands, the classic Cali Crushers have semi-fine teeth for a smaller grind ideal for joints and bong bowls. The textured lid helps with turning when the grind gets sticky from premium nugs.

Best Splurge Cannabis Grinder:

Cali Crusher Homegrown Quicklock Grinder

Price: $89.99

The Cali Crusher Homegrown is a workhorse that never tires. The four-piece grinder is the product of years of research and design updates. The Crusher solves many common problems with grinders like cross-threading, grip issues, and grinding efficiency. It has large areas without teeth in the grinding plate for you to load your weed nugs before the grind. Its quarter-turn locking system and easy turn lid ensure that you won’t ruin your grinder by cross-threading it.

Typical grinders focus on shredding your herb into small pieces, but they can make the grinds dense and more difficult to combust. The Crusher's teeth cut and fluff your bud to produce a perfect, pillowy pile of herb. The extra-wide teeth also come with a lifetime warranty against damage.

What to Look for in a Quality Cannabis Grinder

Buying a good weed grinder will reward you for years with better burning joints and more potent vaporizer bowls. A well-made grinder has a few essential qualities.

What Material Should Your Weed Grinder Be?

The grinder’s material can vary. We recommend high-grade anodized aluminum for its durability in combination with light weight.

Our finest quality grinders are from a single piece of machined aluminum, fitted for a seamlessly smooth grinding experience. A great grinder is easy to turn but stays tightly shut when you need it to.

How Many Compartments Should Your Grinder Have?

Herb grinders have multiple compartments. The minimum number of plates required for a grinder to function is three — two with teeth and another with a compartment to catch the ground weed.

A grinder can have many more plates that serve other functions such as sifting out kief, increasing storage capacity, and grinding weed into smaller particles. Depending on whether you travel with your grinder or if you will use it for pipes or rolling joints, the size matters. In some cases, especially if you have the funds, it’s worth having two grinders for specific functions.

Grinders that produce a coarser grind are usually perfect to use with pipes, bowls, and joints because they allow for a nicely broken down final product that isn’t too powdery. When your bud is a fine, powdery consistency, it can make it a bit more challenging to roll into a joint or pack into a bowl.

How Big Should Your Weed Grinder Be?

A giant grinder is great for keeping at home on your rolling tray, ready to help you load blunts and joints. A smaller grinder or a two-piece grinder is perfect for traveling and pocket storage.
