Instead of relying on metal surfaces sliding against each other, the ZAM Stainless Steel Ball Bearing Grinder uses a precision ball bearing inside the grinding chamber. This prevents residue build-up from slowing the lid, and eliminates metal-on-metal contact along the chamber walls.
The result is smoother operation, reduced residue drag, and a cleaner grind.
Features & Specifications
Core Features
- Precision Ball-Bearing Drive – Built around a high-performance 608Z stainless steel bearing for ultra-smooth, low-friction grinding.
- Spinning Top Design – The bearing-driven mechanism allows the grinding teeth to rotate freely. No friction on the side walls means continuous, smooth rotation, 100% of the time.
- Threadless Quick-Connect System – No threads to jam or cross-thread. Simply pull apart to separate sections.
- 360° Magnetic Connection – Strong neodymium magnets keep the grinder securely closed while allowing quick access.
- Deep 3-Piece Storage Container – Save the potency, and your ground material, in a deep storage chamber.
- Sharp Stainless Steel Teeth – Diamond-style teeth slice sticky herbs with minimal effort.

Grinding is so easy because the ball bearing allows it turn easily. You'll love it!
I have a Zam 4 piece Stainless Steel Grinder as well and I loved that one so much I decided to get another. I was tired of using my aluminum grinder on my secondary strain (I smoke one strain one day then the next day I do the other and soon and so forth) I got this one on sale and I wanted to give the ball bearing one a go.. It makes grinding so easy. Even on sticky strains it works much better. It doesn't get gummed up and hard to spin. My only complaint, and this is probably because I only use my dry herb vape, is the post with the mag in the base where the ground herb goes makes it difficult to fill my vape tube. (Arizer Solo Max 3) Would be nice to not be threadless for that reason only. Otherwise I can see that threadless design is the cats meow. The annoyance for me with the vape is the only reason for the 4 stars. Zam is top notch at a great price. I paid more for my smaller aluminum Santa Cruz shredder that went dull quickly and has pieces of aluminum missing. I can only assume I vaped them and that's not great.
Love it!
An awesome grinder and the bearing makes spinning effortless.
