17-4 PH Stainless Steel Billet Stepdown Series Basket
⭐This is a precision CNC-machined basket, not a stamped one. Each basket is CNC machined from a solid block of 17-4 PH Stainless steel and finished with precision laser-cut holes. It will not permanently deform under 9 bar, unlike SUS 304 and 316.
Why choose a stepdown basket?
A narrower basket naturally restricts flow, meaning you can grind coarser for the same recipe compared to a standard 58mm basket.
This helps reduce astringency and bitterness by minimizing the impact of ultra-fine particles.
The deeper puck design also prevents ultra-fines from passing through the bottom layer, resulting in less channeling and more consistent extractions.
The taste difference between a standard 58mm basket and a step-down basket is striking. The step-down version produces a brighter, cleaner, and higher-clarity espresso.
This means you can enjoy the benefits of a step-down basket without changing your entire coffee setup.
Puck Screens and Spring are optional. When your dose is about 10–25% below the basket’s full capacity, extra headspace can become an issue. Placing the spring on top of the puck screen helps eliminate that gap while also working as a shower screen to create back pressure.
The added back pressure makes it possible to grind a bit coarser, extend shot times, and achieve higher brewing pressures.
We added the longer base plates, which can be used as a standalone tamper or with our spring impact tampers.
Basket Specification:
500 Holes: Single-dose basket designed for low doses (7–10g). Ideal for low-ratio espresso, especially when brewing high-end specialty coffee beans. It’s easier to dial in and requires a significantly coarser grind size compared to standard single-dose baskets.
750 Holes: Higher body and sweeter espresso. It is easier to dial in due to the tapered bottom. Light/Medium Roast (Compatible with our 49mm accessories)
2000 Holes: Higher extraction with the increased hole count. This basket is aimed at high clarity and acidity. It is very good for single-origin light roast coffee.
These baskets work well with our lab-grade paper filter, 3μm Slow Flow, and 20μmFast Flow.
Magnetic: Yes
Thickness: 0.8mm
Material: 17-4 PH Stainless Steel

Inner Diameter 58mm side: 59mm
Make sure your machine is compatible with our baskets based on the measurements we provide, as we are not responsible for incompatibility.
If the basket has difficulty getting in your portafilters, then you may get our portafilter designed to accommodate stepdown baskets or change the size of your portafilter spring to a thinner one.
Details may change in future releases.
