BIGFUN! Large Grinder

The BIGFUN Large at 2.5 inches is best suited for users who grind more than a single-session amount at a time, who regularly share with one or more people, or who prefer to grind in batches and store ground herb in the chamber between uses. The 2.5-inch grinding surface and larger storage chamber mean fewer reloading cycles per session compared to the 2.2-inch Medium. It is also a good fit for users who have found personal-sized grinders too small but do not need the maximum capacity of the 3-inch XL. The large kief chamber accumulates a harvestable supply of pollen faster than the smaller models.

6061 aluminum is an alloy grade used extensively in aerospace and precision manufacturing applications. BIGFUN chose it for their grinder lineup because it machines cleanly and precisely via CNC milling, holds tight tolerances for consistent tooth geometry and thread fit, and resists corrosion under normal use conditions. The alloy is also lightweight, which makes the grinder comfortable to hold and carry. The combination of CNC milling from 6061 stock means each BIGFUN grinder has a consistent, repeatable internal shape that maintains smooth operation over time. The anodized finish applied after milling further hardens the surface and seals it against scratches and oxidation.

Yes. All 4-piece BIGFUN grinders include a mesh pollen screen and a dedicated kief collection chamber at the base. As herb is ground and stored over multiple sessions, the finest trichome-rich particles pass through the mesh screen and accumulate in the bottom chamber. The center post with magnet is positioned on the lower set of teeth in BIGFUN grinders rather than the lid, which allows the lid to be fully open and accessible for loading whole nugs. A scraper tool is useful for collecting kief from the chamber walls when enough has built up to harvest. The pollen screen mesh sifts only the finest particles, keeping larger plant material in the main storage chamber.

Both BIGFUN Large Grinder listings at Haze Smoke Shop are the same 2.5-inch 4-piece 6061 aluminum grinder with the same diamond teeth, mesh screen, and anodized construction. The two separate listings represent different color variant groupings available in inventory. If you have a specific color preference, contact Haze Smoke Shop before ordering to confirm which colors are currently in stock under each listing.

BIGFUN offers four grinder sizes across their CNC-milled 6061 aluminum lineup. The Small at 2 inches is the most compact and travel-friendly option. The Medium at 2.2 inches is the daily driver size, balancing portability and capacity for most users. The Large at 2.5 inches provides more grinding surface and storage for users who grind larger quantities or share. The XL at 3 inches is the largest, suited for group sessions or users who prefer to grind in bulk. All four sizes use the same diamond-shaped teeth design, anodized finish, and mesh pollen screen construction. The 2-piece Medium variant is also available for users who want a simpler design without kief collection.

After each session, use a small stiff brush to clear herb debris from the diamond-shaped teeth and the holes in the grinding plate. To deep clean, disassemble all four pieces and soak the aluminum components in isopropyl alcohol for 20 to 30 minutes to dissolve resin buildup. Brush away loosened residue, rinse thoroughly with warm water, and allow all pieces to dry completely before reassembling. The anodized finish is alcohol-resistant. For the mesh pollen screen, soak rather than pressing on the mesh directly to avoid distorting it. Use the scraper tool to harvest any accumulated kief from the pollen chamber before soaking. Tap the grinder gently before disassembly to encourage remaining herb to fall through the screen.
