# 58mm Portafilter Accessories | Precision Tampers, Distributors & WDT Tools

## 58mm Portafilter Accessories — The Complete Puck Prep Collection

The **58mm portafilter** is the industry standard — used by Breville Barista Express, Gaggia Classic, Rancilio Silvia, La Marzocco, Nuova Simonelli, and hundreds of commercial machines. All products in this collection are purpose-designed for the 58mm group.

### 58mm vs 58.5mm — Which Tamper Do You Need?

This is the most common question in the 58mm group. Here's the definitive answer:

-   **58mm tamper** — Fits the nominal basket diameter. Leaves a thin 0.25–0.5mm ring around the edge. Suitable for pressurized baskets and budget setups.
-   **58.5mm tamper** — Precision fit for IMS, VST, and most aftermarket unpressurized baskets. Closes the edge gap completely. _This is what specialty cafes and home baristas with unpressurized baskets use._

**Rule of thumb:** If you're using the stock basket that came with your machine, 58mm works fine. If you've upgraded to an aftermarket basket (IMS, VST, La Marzocco, etc.), measure the inner basket diameter — most are closer to 58.5mm.

### The 58mm Puck Prep Stack

Used by specialty baristas worldwide:

1.  **WDT** — Stir and aerate the dosed grounds with a fine-needle WDT tool. Takes 8–10 seconds. Eliminates clumps and creates a uniform density bed before levelling.
2.  **Gravity Distributor (58 or 58.5mm)** — Place on portafilter, rotate 2–3 quarter turns. Centrifugal levelling without downward pressure — grounds settle to their natural rest angle.
3.  **Constant Force Tamper** — Apply consistent pressure. Spring-loaded tampers click at a set force (usually 30 lb / 15 kg) so every shot gets the same compaction.
4.  **Puck Screen** — Optional but highly recommended. Sits on top of the puck and distributes water evenly across the surface. Keeps the shower screen clean between backflushes.

### Frequently Asked Questions

#### What's the difference between 58mm and 58.5mm tampers?

The nominal basket diameter is 58mm, but most precision aftermarket baskets (IMS, VST) have an inner diameter closer to 58.5mm. A 58.5mm tamper fills this to the wall, preventing grounds from escaping around the edge during tamping — the main source of side-channeling.

#### Do I need a distributor if I already have a tamper?

They serve different purposes. A **tamper** compresses the grounds. A **distributor** levels the grounds before you tamp. Using both is the current best practice — level first (distributor), then compress (tamper). Many baristas report that a distributor + tamper combination is more consistent than either alone.

#### What is a WDT tool and do I really need one?

A WDT (Weiss Distribution Technique) tool has thin needles that stir the dosed grounds to break up clumps caused by static electricity and compaction in the grinder. Studies show that WDT reduces puck density variation by 30–50% compared to just tapping or finger-levelling. For any machine with a single-boiler and a mid-range grinder, WDT is one of the highest-impact improvements you can make.

#### What is a puck screen used for?

A 58mm puck screen is a fine mesh disc that sits between the tamped puck and the group head shower screen. It distributes the first water contact evenly across the puck surface (preventing the initial jet from gouging a channel), and it keeps your shower screen free of coffee oils between backflushing sessions.
