Description
Clumped Grounds Cost You The Shot
Dry-clumped coffee grounds create channels inside the puck, and water finds the path of least resistance long before it reaches your cup. The SE Pro Needle Distributor is the WDT distributor tool built to break up those clumps at the exact depth you dial in, every single time.
Engineered For Repeatable Distribution
The SE Pro sits directly on your 58mm basket and moves back and forth while you press, working the needle array through the grounds instead of skimming the surface. Stepless depth adjustment means the needles reach exactly as deep as your dose demands — no more, no less. The result is a puck with consistent density from rim to centre, shot after shot.
Benefits At The Basket
- Stirs grounds while pressing, so distribution and pre-tamp happen in one motion
- Stepless depth control adapts to light, medium, and dark roast doses
- Concentric needle geometry covers the full basket radius, leaving no dead zones
- Magnetic base seats and releases the tool without wobble or misalignment
Four Details That Do The Work
Every feature below exists to solve one problem inside the basket: uneven density that leads to channelling.
Bidirectional Stirring
The needle head moves back and forth as you press down, breaking clumps rather than just poking at them — the core of correct WDT technique.
Stepless Depth Adjustment
Set stirring depth to match your dose and basket, from shallow doses to deep, high-yield baskets, without fixed notches limiting you.
Concentric Needle Array
Needles are arranged in concentric circles, so every pass covers the basket edge to centre with uniform reach.
Magnetic Mounting
The tool locates and locks magnetically onto compatible baskets, then lifts away clean — no threads, no fiddly alignment.

Before You Add It To Your Bar
Will this WDT distributor tool fit my portafilter?
It fits 58mm 2-ear portafilters on select models. It is not built for 58mm angle-ear or 58mm 3-ear portafilters, so check your basket type before ordering.
How do I clean the needle array?
Rinse the needles under running water immediately after use to prevent oils from drying between them, then dry before storing.
Does the stirring depth need resetting for every dose?
The adjustment is stepless, so you set it once for your usual dose and basket, then only change it if you switch to a noticeably different fill level.
Is the magnetic mount strong enough for daily café use?
Yes. The magnetic base is designed for repeated placement and removal, holding position through the full stirring motion without slipping.
What is this tool made from?
The body combines PC, NR, aluminium alloy, and SUS304 stainless steel — the needles are stainless steel for durability and easy cleaning.
A WDT Distributor Tool Built For Every Shot
This tool suits home baristas refining their morning routine and café counters pulling back-to-back shots on 58mm 2-ear setups. If clump-free, even distribution matters to your extraction, the SE Pro earns its place in your dosing kit.
