The MHW-3BOMBER Yu Series Cyclone Needle Distribution Tool ( 51 mm) is a precision WDT tool designed to ensure even distribution of ground coffee in the portafilter and more consistent espresso extraction. Thanks to its thoughtful design, it helps break up clumps formed during grinding and evenly distribute the coffee in the basket. The result is a more stable water flow, a more balanced extraction, and a cleaner flavor in every cup.
The tool’s design is inspired by a children’s toy —a bamboo dragonfly that rises into the air when spun. It is this motif that gave rise to the characteristic “cyclonic” movement of the needles, which naturally mixes the coffee in the portafilter as it works. The combination of playful inspiration and precise technical execution thus creates a tool that is not only functional but also a visually interesting addition to any barista station.
A practical feature is the magnetic base, which contains ten magnets for precise placement on the portafilter. Thanks to this, the tool stays firmly in place during use, and there is no risk of it shifting while distributing the coffee. Another major advantage is the adjustable needle depth —with a simple twist, you can adjust their reach according to the basket size or amount of coffee. Turning clockwise increases the depth, while turning counterclockwise decreases it, allowing you to easily set the ideal range for your workflow.
The entire body of the tool is made of aluminum alloy and SUS304 stainless steel, ensuring high durability, a long service life, and protection against corrosion. A silicone ring on the bottom prevents the tool from slipping, protects the work surface, and covers the needles when the tool is set aside. Another practical feature is the integrated needle storage system in the base, which keeps the tool compact and ready for use.
