xIncrease your espresso insight with a bottomless portafilter
The MHW-3BOMBER 54mm Bottomless Portafilter is designed for hands-on baristas who want to watch every shot unfold. By exposing the flow, crema, and color changes as the espresso exits the basket, you gain real-time feedback that helps you fine-tune technique without guessing.
Design and materials you can rely on
Built to withstand daily use, this portafilter pairs an aluminum alloy body with a SUS304 steel handle and a surface electroplate finish. The result is a durable, corrosion-resistant tool with a substantial, reassuring heft—roughly 500 g (1.1 lb)—that feels solid in hand during long sessions.
- 54mm diameter matches standard baskets for broad compatibility
- Heavy, balanced weight supports stable tamping and consistent grip
- Electroplated finish offers resistance to wear in busy homes or cafés
Everything included for immediate use
Each package comes with a 54mm universal stainless steel precision filter basket featuring 648 holes at 0.3 mm. This design promotes even extraction and helps reduce fines, guiding you toward a cleaner, more predictable cup with a recommended dose around 15 g.
- Includes a 54mm universal filter basket for quick setup
- High-hole basket supports even flow and crema formation
- Recommended dose guidance to help balance shots
Bottomless design: learn, tweak, improve
Seeing the shot emerge provides visual feedback on channeling, flow rate, and crema quality. Use this information to adjust grind size, grind distribution, and tamping pressure, steadily refining your technique over time. The portafilter is detachable for cleaning, with hand washing preferred for optimal care.
