5 Best WDT Tools Reviewed
In this section, we’ll be talking about five of the best WDT tools available. We’ll go over what makes each tool good and highlight some considerations to keep in mind.
Normcore WDT Distribution Tool V3-9
- Needle Width: 0.25mm & 0.3mm
- Number of Needles: 9 Needles
Normcore coffee accessories are generally of excellent quality and so is this espresso stirrer tool.
This WDT tool comes out of the box with 9 needles installed however, you can customize the amount of needles as per your requirements.
Also, it comes with two types of needle thicknesses, 0.25mm & 0.3mm 304 stainless steel needles, its benefit is you can try both and choose the best that works for you.
And replacing the needles isn’t a tough job either, simply open the head or from where you grab it (ABS center shaft) and change them one by one, and let me tell you, it is built with Anodized Aluminum CNC.
The complete length of this device is 103 mm, its diameter is 31 mm, and the length of the needle only is 50 mm.
Overall, it’s a simple and well-built tool that has the potential to break every small clump and distribute coffee grounds uniformly.
Pros
Seamlessly break clumps
Make your setup aesthetically pleasing
The quality and the finishing of the product is super awesome.
Cons
Slightly Overpriced
KNODOS Magnetic WDT Espresso Tool
- Needle Width: 0.25mm & 0.4mm (pre-installed)
- Number of Needles: 6 Needles
The main USP of this espresso stirrer is that you can adjust the needle angle between 90-120 degrees as per your needs with that you can also select the number of needles you want to operate with.
The process of shifting angles and replacing the needles is also quite smooth and easy; actually, I found this one of the easiest in both terms.
I also appreciate its magnetic stand; where magnets on the tool’s head effortlessly attach to the stand for convenient storage and always be close to your setup.
And don’t worry about its build quality as it is a solid build with anodized aluminum and needles with 304 stainless steel.
Pros
Almost all reviews are positive by users
Sturdy stand and perfectly hold the tool
Replacing needles is quite easy
Cons
Not good for those who need more than six needle tool
MEION Espresso Distribution Tool
- Needle Width: 0.35mm
- Number of Needles: 7 Needles
This WDT tool is the cheap and best product we’ve found in our research and it checked all our buying guide[internal link] parameters.
It is ergonomically designed with a patented anti-slip handle, which ensures a comfortable grip in your hand while distributing coffee.
The tool also comes with a cover cum stand that is made with aluminum alloy including the head and the needles are built with food-grade stainless steel.
Pros
Sturdy design
Best for those who are starting their espresso journey
Cons
Feels a little bit heavier than other tools
iCosoni 2 IN 1 Upgrade WDT tool Espresso with Coffee Tamper
- Needle Width: 0.35mm
- Number of Needles: 10 Needles
The company designed this tool in such a way that it can do both of your work of distribution and tamping.
The overall design of the tool resembles a chess pawn that is made with anodized aluminum alloy and it does not cause discomfort in your hands when you use it.
At the bottom of the tool is a Ripple Base Tamper which comes in three sizes of 58mm, 51mm and 49mm which you can choose according to your portafilter size and the tamper also works as a cover/stand to the WDT tool.
The WDT tool comes with a 10-needle setup which is highly configurable which means you can load any number of needles and do your distribution.
The only problem I came across with this is that the WDT tool head is a bit shaky while tamping and it would have been better if there were 4-5 small magnets inside the head of the WDT tool and the neck of the cover that would hold it in place.
Pros
Both the WDT and tamper do their job neatly and no complaints
Save your money and storage space
Good for travel purposes
Cons
WDT tool head wobbles while tamping
Normcore 58mm Adjustable Needle Distribution Tool V2
- Needle Width: 0.3MM
- Number of Needles: 9 Needles
This espresso stirrer tool isn’t like other handheld WDT tools, it is comparatively pretty fast as it requires only a few spins and the mechanism on which it spins is also very smooth.
Normcore designed this in such a way that its nine needles are placed at a certain distance that covers the whole 58mm size portafilter that impressively breaks clumps.
You can also adjust the height of the tool between 18mm-22mm according to your portafilter depth and the process is very simple – you’ll get instructions manual inside the box.
At its base/cover where the needles sit, there are brush bristles that help in cleaning coffee residues stuck in the needle.
One issue a few users complain about is that its needles will go through the same path of coffee grounds over and over and do not create a uniform distribution but instead promote channeling.
However, for most it works perfectly fine and improves their espresso quality – that’s why I’ve not added this point in the cons section.
Pros
Break clumps effectively and pretty fast
Does the job for distribution as well as leveler
Good for busy commercial hours – very fast & low risk of spilling
Cons
Needles bend easily, looks flimsy
WDT Tool Buying Guide
You know that a WDT tool, or an espresso stirrer, quietly plays a vital role in making a perfect cup of coffee.
But what makes one WDT tool better than the rest? Let’s explore.
Length & Thickness
The standard length of a WDT tool needle should be between 50mm-60mm and as the needles are flexible, going any larger than this size will not give you full command over your tool.
And if we talk about the thickness, the optimal needle size for a WDT tool is between 0.25 to 0.4 mm.
If the needle size is too small, it might not create enough space between the coffee grounds, making it challenging to break up clumps effectively and you have to move the tool more than it needs to be.
On the other hand, if the needle is too large, it might create too much space between coffee grounds, leading to channeling and uneven extraction.
Material
In this section, we are only going to discuss needle material and not the head or handle material because it can be made of anything but must be rust-resistant.
For the needle material, it’s recommended to use food-grade 304 stainless steel. This material should possess qualities such as flexibility, strength, and non-corrosiveness.
Needle Types
Currently, there are three types of needles that the WDT tool manufacturers use; looped needles, sharply pointed needles and round/flat needles.
You should avoid the first two types of needles, the looped ones because their thickness and the loop at the bottom can worsen distribution by separating coffee grounds.
WDT tools having sharply pointed needles are good for distribution but still not advisable because they can scratch the bottom of your portafilter basket, many people including myself have faced this issue.
Moreover, if you use espresso paper filters these needles can easily tear them and can also harm you someday using the tool.
The flat/round bottom needles are the ones you should go with as they are good for you, your tools, and of course for the distribution.
Do It Yourself
If for any reason you don’t want to buy a WDT tool, still you can use it by making it for yourself and it isn’t tough to make.
You need acupuncture Needles of size between 0.25mm – 0.4mm, a bottle cork, a drill machine, and a piler.
For making, take a bottle cork and mark the points where you want to insert needles, then with the help of a drill machine of 1/16th size carefully drill the marked points in a straight line or you can use any other sharp object to do so.
Put the needles into holes and look at the length of the needles (test with portafilter), if it’s too long, take a piler and cut the needles.
Test it again and if everything seems fine – you are good to go.
