So Many Grinders: Testing the Metal Large Metal Anodized Grinder

We love grinders of all kinds, and it seems that you do as well since you are reading this (which we greatly appreciate and take pretty seriously). For sheer durability and the most extensive selection available, metal grinders are hard to beat.

This article will look at four of Premium Grinder’s metal grinder suppliers, their offerings, and what might make them a good choice for your next purchase.

Diamond Grind

This family-owned, Texas-based company boasts a wide selection of robust metal grinders. You can choose from five different sizes ranging from 1.5 inches to 3 inches in diameter, nine different colors, and two or 4-part configurations. With over 25 years in the grinder business, you can count on these food-grade aluminum gems to make easy work of your grinding.

Interestingly, each new model year boasts an improvement to the technology, like improving threads and the anodizing process. Plus, you get Diamond Grind’s lifetime warranty on all parts.

EZ Grind

Also manufactured by Diamond Grind, the EZ Grind line of metal grinders provide some unique options. For example, their four-part grinder is available in five different matte colors and four sizes ranging from 2 inches to 3 inches in diameter.

The EZ Grind five-part silver grinder is CNC machined from a single block of 6061 aircraft-grade aluminum for strength and durability. All EZ Grind units sport sharp diamond-shaped teeth and a course and fine screen for better grinding and sifting results.


Small notches around the top and a revolutionary nonstick surface make these some of the most effortless grinders on the market today. Their specialized plating process makes the teeth sharper, harder, and non-toxic.

Available sizes range from the Mimi at 1.5 inches up to 3 inches, with some models offering up to 8 different color options. All models are fabricated from a single block of high-grade aluminum. With features and quality like this is no wonder that Notch Grinders are so popular.


These superbly engineered grinders, made from 6061 aircraft-grade aluminum, are specially treated and anodized for safety and durability. Kannasror grinders present exclusive features and options like removable screens, and deep storage containers with optional glass jars.

The Kannasror product line offers several sizes of grinders, beginning with the 1.5-inch 4-part aluminum grinder, up to 2.5 inches, in either two or 4-part design. The brand also offers a sleek storage puck and a well-built pollen press to complete your ensemble.


These four brands represent the most significant portion of metal units offered by Premium Grinders. We hope that you are finding this information helpful in your grinder search. Still, we are only scratching the surface.
