MHW-3BOMBER Leveler/Distributor 51 mm – height-adjustable for 51 mm portafilters
Set the height to your dose once, place the tool on the portafilter, and turn – the angled faces beneath the base gently push the grounds level. What were hills and valleys a moment ago now sits even, ready for a clean tamp.
An adjustable distributor and leveler for compact 51 mm machines.
What makes the leveler
During the shot, water seeks the path of least resistance through the puck. If the grounds sit unevenly, it flows faster where they're looser – and extraction becomes uneven. The leveler evens out the surface before you tamp: its angled faces on the base push the grounds sideways and level as it turns.
The height is adjusted on the tool so it matches the amount of grounds in your 51 mm basket. A simple motion: place, turn, tamp. Espresso is a craft, not a law – an even bed just makes it more repeatable. Our opinion is one of many.

Who it's for
For anyone with a 51 mm machine such as DeLonghi, Smeg or La Pavoni who wants to distribute their grounds evenly before tamping. The adjustable height fits the tool to different doses.
What you pair it with
A leveler works together with a tamper and a WDT tool. Tampers, WDT tools and puck screens are available affordably in the Normcore Collection and especially finely crafted in the Weber Workshops Collection; more tools are in our Tamper Collection.
And because an even bed only pays off with the right machine, it's worth a look at our espresso machines – supported by our advisory tool.
Frequently Asked Questions
How does a leveler differ from a WDT tool?
The leveler smooths the surface with angled faces; the WDT tool breaks up clumps deep in the grounds using fine needles. Many people use both, one after the other.
How do I adjust the height?
Adjust the height on the tool to match your dose – the base then sinks just deep enough to level the surface without heavily compacting it.
Does the leveler fit my 51 mm machine?
It's made for common 51 mm portafilters. If in doubt, check the inner diameter of your filter basket.
Can I see the tool in person before buying?
Absolutely – come experience it live in our showrooms in Bern (Gerberngasse 44) and Zürich (Hagenholzstrasse 50b). Online, we deliver in 2–4 business days, across Switzerland and to Liechtenstein.
Tip from our coffee roastery
An even distribution really shows with body-rich, sweet roasts. Our Cozy Chocolate and Nutty Delight taste round and are forgiving. For maximum body without any acidity, go for the Very Nutty, for a fruity experience, the Wild Peach. That's our recommendation – one of many.
