MHW-3BOMBER DEX precision basket 58 mm 22 g – Deep Extraction
More grounds, a longer, denser shot: 22 g in the basket, and the water works its way evenly through the deeper coffee bed. In the bottom, the holes sit in clear, rectangular rows.
Nobody needs a new basket. You want one – or you don't. It's a decision born of curiosity, and we respect it either way. If you're here, you know why.
What makes this basket special
The DEX – Deep Extraction – relies on 872 precise holes arranged in a rectangular pattern. The holes are stepped-drilled: this distributes the water evenly across the whole surface and supports a consistent, deep extraction. Made from AISI 304 stainless steel with straight walls and a flat bottom, which helps with even tamping and gives the puck support.
The larger 22 g dose creates a deeper coffee bed and suits stronger, longer shots. We like to work with a 1:2 ratio, so around 22 g of grounds to 44 g of espresso, and let the weight decide, not the stopwatch. It's our observation that the choice of basket fundamentally changes the aroma profile – that's our view, one of many.

Who it's for
For anyone with a 58 mm portafilter who likes larger, stronger shots with more grounds. If in doubt, check whether the 28 mm basket height fits your portafilter. Every budget is welcome, and you belong here because you love coffee – not because you use a particular basket.
What goes with it
The basket fits standard 58 mm portafilters from our portafilter collection. Even distribution beforehand comes from a WDT tool and a tamper – affordable and precise from Normcore, with more material ambition from Weber Workshops.
You'll find the right machine in our coffee machine collection and the grinder in our coffee grinder collection. Still choosing? Use our advisory tool.

Roastery tip
A good basket helps, but the bean makes the flavour. For dense, sweet espresso, we like to reach for Cozy Chocolate and Nutty Delight. If you like it full and round without any acidity, stick with Very Nutty; for a fruity experience, Wild Peach goes into the grinder. That's our recommendation, one of many.
