MHW-3BOMBER 54mm Espresso Dosing Funnel with Magnetic Ring – 54mm Portafilter Accessory DR5547B-OS

Elevate your espresso workflow with the MHW-3BOMBER 54mm Espresso Dosing Funnel

Meet a compact accessory designed to streamline dosing between your grinder and portafilter. The MHW-3BOMBER 54mm dosing funnel threads onto most 54mm portafilters, delivering a stable, magnet-assisted hold that reduces wobble and spill risk as you work. This isn’t about promises—it’s about smoother pours and cleaner counters, with a design that respects your grind decisions and workflow.

Key benefits at a glance

• Magnetic adsorption ring with 10 magnets anchors the outer ring to the basket, offering a stable fit versus traditional rings.
• Bottom hanging design keeps the inner wheel free, expanding powder connection range and avoiding depressions after storage.
• Flared upper opening widens the dosing path, helping contain coffee grounds and minimize countertop mess.
• Made from rust-resistant aluminum alloy, the funnel is light (about 32 g) yet durable, with easy cleanup.

Design details and materials

The funnel’s 54mm inner diameter matches a wide range of 54mm portafilters in the market. Its aluminum alloy construction resists corrosion, so it stays sturdy with regular use. The lightweight form means you can maneuver it without added fatigue during a busy morning routine.

Note that magnetic strength can vary depending on the basket material; strength is typically lower on 304/316 stainless steel or aluminum baskets. This is normal and should be considered when pairing with different equipment.

Real-world use cases

• After dialing in your grind, the funnel helps you portion grounds cleanly without scattering powder on the counter.
• In a busy cafe or home setup, the magnet ring helps keep the ring aligned even during quick tamping or adjustments.
• The compact weight makes it easy to swap between grinders or travel with your setup for weekend coffee runs.

Compatibility and care

Designed for 54mm portafilters, this funnel is not compatible with Breville Barista Express, Pro, or Touch portafilter holders when installed. It can be used with an independent grinder or as part of a broader extract setup. Regular cleaning with a soft brush or cloth keeps the surface free from oils.

Why choose the MHW-3BOMBER funnel?

If you value a cleaner workflow, the MHW-3BOMBER offers a practical blend of stability, protection, and portability. It’s a thoughtful accessory that addresses common dosing challenges without making guarantees, allowing you to explore different dosing approaches with greater confidence.
