What fits a 58 mm machine
By Lin · How we pick · Full Fit Finder
58 mm is the commercial standard, which is the good news: almost every precision basket, tamper and bottomless portafilter on the market is made for it, and parts move freely between brands. The decision that actually remains is tamper diameter, where 58.0 mm and 58.5 mm both exist and seat differently depending on the basket.
Machines in the 58 mm group
- Breville / Sage Dual Boiler (BES920)
- Breville / Sage Oracle
- Breville / Sage Oracle Touch
- Gaggia Classic Pro
- Gaggia Classic Evo / Classic Pro E24
- Profitec GO — Shares the Profitec 58 mm portafilter with the Pro 300 / 400 / 500 / 600 / 700, so parts are interchangeable across that range.
- Profitec MOVE — E61-group machine, so it takes the same 58 mm portafilter as the rest of the Profitec E61 range.
- Quick Mill Pippa

58 mm is the commercial standard, so most third-party tampers, baskets and screens made for prosumer machines will fit.
