About This 【Premium WDT Tool Set 】Our premium 51mm WDT tool includes an anodized aluminum handle and comes with a built-in espresso stirrer holder, metering funnel, WDT tool, and stand to keep your workspace tidy and make cleanup easy. Compatible with Delonghi Dedica Style Series EC680/EC685 and SMEG ECF01. Please note: not compatible with DeLonghi EC9335, EC966, EC9115, or 51mm portafilters. 【Standard Compatibility】 Designed specifically to work with all standard 51mm portafilter baskets, making it a versatile tool for most espresso machines. Comes with a dedicated and compact base that keeps your tool clean, protects the needles, and maintains an organized coffee station. 【Essential for Professional Baristas】Upgraded design reduces steps, boosts efficiency, and lets baristas focus on quality, taste, and service excellence. Utilizes the Weiss Distribution Technique (WDT) with fine needles to break apart coffee clumps and eliminate channeling for a balanced extraction. 【Adjustable Needle Height】Adjust the needle depth to match your basket's capacity by rotating the adjustment ring. NOTE: If the needle doesn't reach the bottom of the basket, don't worry. The centrifugal force created during the wdt tool's rotation will disperse any untouched coffee grounds, which will not affect the taste of the coffee. 【Precision Distribution】The needle-like structure evenly distributes coffee powder, disrupts clumps, and guarantees uniform hot water infiltration for optimal extraction conditions. 【Magnetic Base】Our 51mm espresso distribution tool features 8 magnets at the base for precise basket adsorption, preventing shifting during distribution, making distribution powder even more worry-free. 【After-Sales Service】DREEITO is committed to providing high-quality, professional coffee equipment for coffee lovers and baristas.
