Professional Espresso WDT Tool Improves consistency and extraction: breaks up agglomerated coffee powder to achieve uniform particle distribution, reducing clumping of fines that can cause splatter. When used with proper tamping, it helps minimize uneven flow and can slow shots for improved quality. Removable needles as needed: easy to assemble and disassemble, with support for inserting 3, 4, 5, 6 or 7 needles depending on your needs. The handle head unscrews for simple needle changes. The multineedle design penetrates and redistributes lumps evenly, eliminates channeling, and promotes balanced extraction. Creative design: features a needle and stand with a maximum angle adjustment of 120 degrees, a notable upgrade over traditional WDT tools. Builtin magnet allows the tool to attach to metal surfaces, enabling attachment to our matching metal bracket or to any metal surface such as the side of the espresso machine. Easy and convenient to use: includes 9 needles with a 0.25 mm diameter, plus an additional 16 needles for greater uniformity and efficiency and reduced splashing. The sturdy handle is CNC machined from anodized aluminum, and the spring wires are 304 stainless steel, nonstick, easyclean, rustresistant, and resistant to bending or breaking.
