Ongrok Premium 4 Piece EZ Grinder

The Ongrok Mini EZ Grinder is 55mm (2.2 inches) in diameter while the Premium is 63mm (approximately 2.5 inches). Both share the same core EZ system features: aircraft-grade aluminum construction, 33 triangular teeth, quarter-turn locking, removable kief screen, and neodymium magnetic lid. The Premium adds a scratch-resistant anodized finish and nylon O-rings for smoother, quieter operation. The larger 63mm catch chamber on the Premium can accommodate a small humidity control pack for extended herb storage, while the Mini is the more compact and portable option for minimalist daily carry.

Standard herb grinder compartments rely on threaded connections that gradually accumulate resin in the thread channels during use. This resin buildup creates increasing friction that eventually makes the compartment very difficult to open without tools. The Ongrok EZ quarter-turn locking system replaces threading with a deliberate click-lock mechanism that does not have thread channels for resin to accumulate in. Opening requires a specific 90-degree rotation intent rather than a gradual unscrew motion, so the compartment cannot gradually work itself open during use or transport either.

Nylon O-rings are thin circular seals positioned between the rotating sections of the Ongrok Premium EZ Grinder. They provide two benefits: they reduce friction between the aluminum sections during grinding, making rotation smoother and requiring less grip effort; and they dampen the metal-on-metal contact sound during grinding, making the operation quieter. Non-stick nylon material also helps prevent herb particles from binding between sections. These O-rings are the feature that most clearly distinguishes the Premium from the Mini EZ Grinder in terms of the grinding feel and sound experience.

Yes. Ongrok specifically notes that the 63mm catch chamber is large enough to accommodate a small or mini humidity control pack alongside stored ground herb. A Boveda or similar small humidity packet placed in the catch chamber alongside ground herb helps maintain the moisture content of the herb during storage, which preserves flavor and texture over a longer period than storing herb at ambient humidity. This is particularly useful for users who grind a larger quantity at once and store it in the grinder for multiple sessions.

The 33 triangular teeth produce a medium-to-fine grind. This output is versatile and suits most standard herb consumption formats: packing hand pipes, filling bowl pieces, loading water pipes, rolling papers and cones, and loading most dry herb vaporizer chambers. For users who prefer a coarser output, fewer lid rotations produce a less refined result. The triangular tooth profile is designed for efficient cutting rather than tearing, resulting in an even output with a consistent particle size across the ground material.

Remove the kief screen by lifting its handle and turning it counter-clockwise to detach. Harvest accumulated kief from the catch chamber with a brush or scraper before cleaning. Separate all four pieces using the quarter-turn unlock and magnetic lid. Soak the aluminum components and detached screen in isopropyl alcohol for 20 to 30 minutes. Brush away dissolved residue from the triangular teeth, chamber walls, and screen mesh. Rinse with warm water and dry completely. Reinstall the kief screen by rotating it clockwise until seated. Wipe the nylon O-rings with a dry cloth rather than soaking them in alcohol.
