Master your espresso workflow with the MHW-3BOMBER 58mm Magnetic Coffee Dosing Funnel, designed for professional consistency and a spotless bar. Featuring a strong magnetic lock and precision fit, this dosing ring keeps every coffee ground where it belongs — in your portafilter. Key Features 10-Magnet Lock-On System: Features 10 powerful magnets evenly spaced for secure attachment to your 58mm portafilter. Provides a stronger hold and improved stability compared to stainless steel funnels, preventing slips or drops. Bottom-Hanging Design: Attaches around the outer rim of your portafilter basket without blocking the inside area. This improves coffee distribution and ensures there’s no indentation or uneven tamp after removing the funnel. No Mess, No Waste: The flared top opening expands the dosing area and catches stray grounds — keeping your counter clean and reducing coffee waste during grinding and distribution. Premium Aluminum Alloy: Built from lightweight, corrosion-resistant aluminum alloy, weighing only 32 grams. Durable yet gentle on your portafilter, and tough enough to handle daily use without dents or cracks. Universal 58mm Fit: Compatible with most 58mm portafilters, including Profitec, ECM, Rocket, Lelit, Breville Dual Boiler, and other commercial-style espresso machines.
