Santa Cruz Shredder Grinder – Large 4pc – 2.75″

The Santa Cruz Shredder uses a patented tooth geometry developed using Siemens CAD software to optimize the shredding angle. Each tooth has clearances on both sides, allowing the grinder to cut herb on both the forward and reverse rotation. This bidirectional cutting means herb is shredded on every movement of the lid rather than only on the downstroke, reducing the number of rotations needed and producing a more consistently fluffy result. The teeth are rounded at the base for strength, which prevents them from dulling or developing burrs that could contaminate the ground herb. The result is consistent output across thousands of grinding sessions.

The Large SCS grinder measures 2.75 inches in diameter compared to 2.12 inches for the Medium, giving it nearly 70 percent more surface area in the grinding chamber. This means more herb can be loaded and ground in a single cycle, reducing reloading for heavy users or group sessions. The larger chamber also makes it easier to handle and load herb without pieces falling out. The larger kief catcher accumulates more pollen over time before needing to be emptied. Users with larger hands may also find the Large easier to grip and rotate comfortably. The trade-off is that it is larger to carry in a pocket or small bag compared to the Medium.

Santa Cruz Shredder subjects all aluminum grinder components to a medical-grade ultrasonic cleansing process before shipping. This process uses high-frequency sound waves in a medical-grade solution to generate microscopic cavitation bubbles that reach into all recesses, crevices, and thread surfaces of the machined aluminum. The cavitation removes all traces of machining lubricants, metal shavings, polishing compounds, and other contaminants that accumulate during CNC manufacturing. The result is a grinder that arrives completely clean, free of the metallic taste or odor that can be present in unprocessed aluminum grinders. This process is why SCS markets their grinders as medical-grade.

Yes. Santa Cruz Shredder includes a guitar-pick-style triangle scraper with their 4-piece grinders. The scraper is useful for collecting kief that accumulates on the walls and screen of the kief chamber over time. The triangle shape allows access to the curved edges of the bottom chamber where kief tends to settle. The scraper is also helpful for loosening compacted kief that has hardened against the surface after extended storage. For very thorough kief collection, some users freeze the grinder before scraping, as cold temperatures cause the kief to harden slightly and release from surfaces more cleanly.

Regular maintenance involves using a small stiff brush to clear herb debris from the teeth and screen after each session. For deeper cleaning, freeze the disassembled grinder for 20 to 30 minutes, then knock each piece gently to dislodge frozen resin. Soak aluminum components in isopropyl alcohol for 20 to 30 minutes, brush clean, rinse with warm water, and dry completely. The T304 stainless steel screen can be cleaned by soaking in alcohol and rinsing; avoid pressing on the screen while cleaning as it can stretch. The proprietary threads are resistant to cross-threading, but always align threads carefully before closing to maintain smooth assembly over the long life of the grinder.

Yes. The Santa Cruz Shredder Large 4-piece grinder is available in multiple anodized aluminum color options. The anodizing process creates a hard, corrosion-resistant surface that incorporates color during the electrochemical treatment rather than applying it as a paint layer. This makes the color integral to the aluminum surface and resistant to peeling or fading under normal use. Available colors vary and may include options such as black, purple, red, green, blue, and rasta, depending on current inventory at Haze Smoke Shop. Contact the shop for current color availability if a specific option is desired.
