Distribution Is the Foundation. The YU-Series Gets It Right. The MHW-3BOMBER YU-Series Cyclone WDT Tool is engineered for baristas who understand that distribution is where consistent extraction begins. Ultra-fine needles break up clumps and redistribute grounds evenly throughout the basket before tamping — eliminating dry pockets, reducing channelling, and setting up every shot for balanced, repeatable extraction. The standout feature is the 10-magnet base: ten embedded magnets lock the tool firmly onto the portafilter basket rim during distribution. The needle works the grounds; the base stays planted. No shifting, no tilting, no hands holding it in place. Needles retract and store cleanly inside the base between shots. Available in 51mm, 54mm, and 58mm. $99.90. Features 10-magnet base system — ten embedded magnets provide a firm, stable lock onto the portafilter basket rim. No shifting, no tilting during distribution. The strongest magnetic attachment in this WDT range. Retractable needle storage — needles retract and store cleanly inside the base when not in use. Ultra-fine tips are protected from damage, and the bench stays clear between sessions. Adjustable stirring depth — clockwise to go deeper, counterclockwise to retract. Dial in the exact penetration depth for your basket size, dose weight, and grind profile. Non-slip silicone ring base — protects the portafilter rim from scratching during placement. Stable on any surface. SUS304 stainless + aluminum alloy construction — food-grade stainless steel for the needle and core components, aluminum alloy for structural rigidity, silicone and PP for grip and protection.

The Sword WDT uses a single magnetic base and 13 needles exposed during use. The YU-Series Cyclone uses a 10-magnet base for a stronger, more stable lock, adds retractable needle storage for tip protection and bench cleanliness, and is sized across 51mm, 54mm, and 58mm. If you already have the YU-Series tamper, the Cyclone WDT completes the YU-Series puck prep lineup.
