Stainless Steel Coffee Dosing Ring

Clean dose. Zero scatter. Every grind, every time.

The MHW-3BOMBER Stainless Steel Coffee Dosing Ring sits on your portafilter basket and catches every ground from your grinder — no scatter onto the rim, no waste on the bench, no mess to clean up mid-workflow. Food-grade SUS304 stainless steel, a flared mouth opening for maximum catch area, and a simple press-fit placement that works with any standard 51mm, 54mm, or 58mm portafilter.

Key Features:

• Flared Mouth Design | Maximum Catch Area: The flared upper rim expands the opening beyond the basket diameter — catching grounds from any grinder angle without spillage onto the portafilter rim or bench surface. Every ground goes into the basket, not around it.
• Food-Grade SUS304 Stainless Steel: Precision-formed from food-grade 304 stainless steel — corrosion-resistant, hygienic, and built for daily use without degradation. Safe for direct contact with coffee grounds and easy to keep clean.
• Press-Fit Placement | Simple Workflow: Sits cleanly on the portafilter basket rim with no magnets, no clips, no threading. Place it, grind, lift it off — a seamless addition to your dosing workflow that adds zero friction and removes a lot of mess.
• Easy Maintenance | Rinse & Ready: Clean with water and a brush or sponge — SUS304 resists staining and coffee oil buildup. Quick to clean, quick to dry, always ready for the next dose.
