IASO grinders are precision machined from 100% stainless steel for a solid, durable design made for years of everyday use.
Each grinder is CNC machined at our workshop in Essex Junction, Vermont, with diamond-shaped teeth, a knurled grip, strong magnetic lid, and clean, straightforward construction.
IASO stainless steel grinders are available in two sizes:
1.75" Grinders
Our most compact option. Easy to carry, easy to store, and available in both 3-piece and 4-piece designs.
2.5" Grinders
Our larger option with more room and increased capacity. Available in both 3-piece and 4-piece designs.
3-Piece Grinders
Simple and straightforward, with fewer components and a deep, curved bottom chamber.
4-Piece Grinders
Add a removable stainless steel sift screen and separate bottom collection chamber. Each includes our 40x40 medium stainless steel sift screen, with a 60x60 fine mesh screen available for a finer, more selective sift.
Our grinders feature diamond-shaped teeth for consistent cutting, a knurled exterior for a secure grip, and a strong magnetic lid.
There are no painted or coated grinding surfaces — the material you see is the material you get.
They're also easy to disassemble, clean, and maintain. Replacement screens, gasket rings, and other components are available to help keep your IASO grinder in use for years.
Choose your size. Choose your configuration. Built the IASO way.
