The SLX Ceramic Coated Grinder V2.5 62mm is the perfect grinder. The innovative ceramic nonstick coating found on every SLX grinder provides a smooth & clean grind with every effortless twist. Every SLX herb grinder is machined from 7075 aluminum, the alloy of choice for precision applications - from high performance jet aircraft to Space-X rockets. With exceptional strength, perfect balance, and unparalleled durability, your SLX grinder will last a lifetime. SLX herb grinders feature drum tight stainless steel screens with a fine micron size - ensuring only pollen gets filtered, not pieces of herb. Perfect for pressing. And they lift out without threads! ZERO Teflon® or PTFE Teflon® (PTFE) fumes are so toxic when inhaled that Dupont® had to ban its use in the tobacco industry. Even if we could use PTFE, we wouldn't - PTFE coatings are plastic based and not durable enough for serious use. You deserve the best when you buy a SLX herb grinder, and Teflon® doesn’t cut it.
