MHW-3BOMBER DEX Precision Basket 58 mm 20 g – Deep Extraction
You turn the empty basket in the light and see the holes sitting in clean rows – rectangular pattern, finely drilled. During the shot, the water then runs calm and even through the whole bed.
Nobody needs a new basket. You want it – or you don't. That'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 openings in a rectangular layout. The holes are stepped-drilled: this spreads 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 base, which helps with even tamping and gives the puck support.
We like to work with a 1:2 ratio, so around 20 g of grounds to 40 g of espresso, and let the weight decide, not the stopwatch. Taste and smell are inseparable here: a large part of what we experience as aroma happens retronasally, as the espresso passes over the tongue toward the throat. It's our observation that basket choice changes the aroma profile fundamentally – that's our view, one of many.

Who it's for
For anyone with a 58 mm portafilter pulling a medium to larger shot who enjoys working with their extraction. If in doubt, check whether the 26 mm basket height fits your portafilter. Every budget is welcome. You belong here because you love coffee – not because of a particular basket.
What pairs well with it
The basket fits standard 58 mm portafilters from our Portafilter Collection. For even distribution beforehand, a WDT tool and tamper help – affordable and precise from Normcore, with more material ambition from Weber Workshops.
You'll find the matching machine in our Espresso Machines Collection, the grinder in our Coffee Grinders Collection. Still deciding? Use our advisory tool.

Roastery tip
A good basket helps, the bean makes the taste. 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.
