For home espresso enthusiasts using compact machines, finding high-quality gear sized for setups smaller than 58mm can be a challenge. Because virtually all precision accessories were historically made for 58mm group heads, many home baristas were left without the right tools to upgrade their setups. Thankfully, Tough Coffee stepped in to fill that gap. Established in 2014, Tough Coffee crafts workflow-focused tools out of a state-of-the-art facility in Shandong, China. By collaborating closely with industry professionals, Tough Coffee offers a wide range of practical gear designed for both 58mm commercial platforms and smaller domestic setups.

The Tough Coffee 3-Ear Bottomless Portafilter is engineered specifically for 51mm machines, such as the De'Longhi Dedica Series, as well as select SMEG and Saeco appliances. It features three ears (or 'wings') along its rim to slot securely into the proprietary group heads of these and similar machines. Without spouts blocking the view, this naked portafilter allows you to observe your shot in real time, making it easy to spot channeling, refine your puck prep, and pull more consistent, better-tasting espresso. The sturdy ABS handle is also detachable, allowing you to easily swap it out if required.
