A grinder is the cheapest upgrade that changes every session. Even grind means an even burn, which means bowls that stay lit and joints that do not run down one side. Everything on this page is under $20 and made from metal rather than the plastic grinders whose teeth round off within weeks.

How many parts do you need?

  • Two-part — grinds and holds. Compact and the cheapest option, with no kief collection
  • Three-part — adds a chamber below the teeth, so ground herb drops through and stays even
  • Four-part — adds a screen and a kief catcher underneath, which is worth having once you use it regularly

What matters at this price

Check the teeth are cut rather than moulded, and that the magnet in the lid actually holds. Aluminium is standard and fine. The kief screen mesh matters more than the grinder body, since too coarse a screen lets ground herb through and too fine a screen collects almost nothing.

For technique and what the kief chamber is really for, read our guide on choosing a weed grinder. If you are rolling, an even grind is most of the answer to a joint that burns badly, and our post on packing a cone covers the rest.

The complete range is in our weed grinder collection, and rolling papers and cones are the natural companion.

Common questions

Is a $15 grinder worth it over a $40 one?
For most people, yes. Premium grinders buy you better tolerances and a smoother action, but a solid metal four-part at this price does the actual job. Grinders fail from stripped teeth and weak magnets, and neither is guaranteed by price.

Do I need the kief catcher?
Not to grind. But it collects for free something you would otherwise lose, and it takes weeks of normal use to build up a usable amount.

How do I clean a grinder?
When it starts sticking, take it apart, brush out the teeth, and wipe with isopropyl. Freezing it first makes stuck resin brittle and much easier to remove.
