FAQ
What makes the CNC milled teeth better than standard ones?
CNC milling creates sharper, more uniform teeth that cut cleanly rather than tear or crush. This means you get a more even grind with less effort, and your herbs stay fresher longer without over-processing.
How does the 4-part design work?
The top chamber holds your herbs and has the grinding teeth. Turn it and material falls through a mesh screen into the second chamber for coarser pieces. Finer particles drop through a second mesh into the third chamber, while kief (the fine powder) collects in the bottom chamber with its own screen.
Is this grinder easy to clean?
Yes. All four parts separate easily by unscrewing. Rinse each section under warm water and dry thoroughly. For stubborn residue, use a soft brush. Avoid harsh chemicals that might damage the aluminium finish.
