Does it fit every 58 mm portafilter?\u003c\/h3\u003e\n\u003cp\u003eIt is designed for standard 58 mm portafilters, but basket and portafilter dimensions can vary slightly by manufacturer. Confirm compatibility if your machine uses a non-standard basket or unusually shaped portafilter.\u003c\/p\u003e\n\u003ch3\u003e3. How many needles does it use?\u003c\/h3\u003e\n\u003cp\u003eThe distributor uses 10 needles.\u003c\/p\u003e\n\u003ch3\u003e4. What are the needles made from?\u003c\/h3\u003e\n\u003cp\u003eThe supplied product listing states that the needles are made from stainless steel.\u003c\/p\u003e\n\u003ch3\u003e5. What does a WDT tool do?\u003c\/h3\u003e\n\u003cp\u003eA WDT tool breaks apart clumps in freshly ground coffee and redistributes the grounds before tamping.\u003c\/p\u003e\n\u003ch3\u003e6. Does WDT help reduce channeling?\u003c\/h3\u003e\n\u003cp\u003eYes. More uniform distribution can reduce areas of uneven density that contribute to channeling during espresso extraction.\u003c\/p\u003e\n\u003ch3\u003e7. Is this a manual tool?\u003c\/h3\u003e\n\u003cp\u003eYes. The distributor is operated manually by rotating the upper section while it sits on the portafilter.\u003c\/p\u003e\n\u003ch3\u003e8. Is the needle depth adjustable?\u003c\/h3\u003e\n\u003cp\u003eYes. MUVNA states that the working height can be adjusted to accommodate different coffee doses and basket depths.\u003c\/p\u003e\n\u003ch3\u003e9. Should I use it before or after tamping?\u003c\/h3\u003e\n\u003cp\u003eUse the WDT tool before tamping. Distribute the grounds first, remove the tool, then tamp the coffee.\u003c\/p\u003e\n\u003ch3\u003e10. Do I still need a tamper?\u003c\/h3\u003e\n\u003cp\u003eYes. WDT distributes the coffee but does not replace tamping. The puck should still be tamped after distribution.\u003c\/p\u003e\n\u003ch3\u003e11. Can I use it with a bottomless portafilter?\u003c\/h3\u003e\n\u003cp\u003eYes, provided the bottomless portafilter uses a compatible 58 mm basket and rim.\u003c\/p\u003e\n\u003ch3\u003e12. Is it suitable for commercial use?\u003c\/h3\u003e\n\u003cp\u003eYes. Its fast rotary workflow can be useful in both home and professional espresso preparation, although durability under very high-volume café conditions will depend on usage and maintenance.\u003c\/p\u003e\n\u003ch3\u003e13. How should I clean the needles?\u003c\/h3\u003e\n\u003cp\u003eBrush or wipe away dry coffee grounds after use. Avoid immersing the complete rotating mechanism unless MUVNA specifically confirms that the full assembly is washable.\u003c\/p\u003e\n\u003ch3\u003e14.
