End the Mess With a Magnetic Dosing Ring

You know the routine. You grind, you dose, and somehow coffee grounds end up everywhere except inside your portafilter. This magnetic dosing ring puts an end to scattered grounds for good. An eight-point magnet system locks firmly onto your portafilter basket, creating a secure seal that catches every last particle during grinding.

Whether you single-dose or grind directly into the basket, the 40-degree expanded funnel opening gives you a wide target that makes even the messiest grinders behave. Flip it, tap it, invert it. The magnets hold strong through your entire workflow.

CNC Aluminum Espresso Funnel Built to Last

This is not injection-molded plastic. Each ring is precision-machined from a single block of aerospace-grade aluminum using CNC equipment. The result is a tool with tight tolerances, smooth edges, and a satisfying heft that feels purposeful in your hand. Available in grey and silver finishes, it looks right at home next to your espresso grinder and machine.

Keep Your Workflow Clean and Consistent

A tidy puck starts with a tidy dose. When grounds scatter, you lose consistency and waste expensive beans. This espresso dosing funnel ensures every milligram lands where it should, giving you a more even distribution before you even pick up your WDT tool. Less waste, better extraction, cleaner countertops.

Cleanup takes seconds. Run it under strong water flow and it is spotless, ready for the next shot. No crevices, no trapped grounds, no fuss.

F.A.Q.

How strong are the magnets on this dosing ring?

The eight-point magnetic system provides a seriously firm hold on your portafilter basket. It stays securely attached even when you invert the portafilter or tap it to settle grounds. You will not have to worry about it sliding off or losing its grip during your dosing workflow. The magnets are built into the aluminum body, so there are no weak points or exposed components to degrade over time.

Will this dosing ring fit my portafilter?

This magnetic dosing ring is designed to work with standard 58mm portafilter baskets (approx. 2.28 inches), which covers the vast majority of semi-automatic espresso machines from brands like Breville, Gaggia, Rancilio, and many commercial machines. The magnetic attachment means it self-centers and grips without needing a precise friction fit, so minor size variations are not an issue.

Is this really CNC-machined aluminum or just cast metal?

Each ring is genuinely CNC-machined from a single block of aerospace-grade aluminum, not cast or injection-molded. You can feel the difference immediately in the tight tolerances, smooth finish, and consistent weight. This one-piece construction means there are no seams, joints, or weak points. It is built to handle daily use in a home espresso setup without warping or degrading.

Can I use this dosing ring every day with my espresso routine?

Absolutely, and honestly that is the whole point. This ring is designed for daily use in your espresso workflow. Place it on your portafilter before grinding, dose your coffee, then remove it and proceed with distribution and tamping. The aluminum construction handles repeated use without showing wear, and the magnets maintain their strength over thousands of cycles. Many home baristas consider it an essential part of their station.

How do I clean this dosing ring?

Cleaning could not be simpler. Just rinse it under a strong stream of water and any residual grounds wash right off. The one-piece CNC design means there are no hidden crevices where old coffee can build up. Dry it with a soft cloth to keep the aluminum finish looking sharp. Avoid abrasive scrubbers or harsh chemical cleaners, as they can mark the surface over time.
