IMS B62.5 Competition baskets
B62.5 is IMS’s line for 54mm group heads — the Breville and Sage machines. Note the tamper figure below: IMS specifies Ø53mm, not the 54mm the format is usually named after. The 54mm is the body diameter, and confusing the two is how people end up with a tamper that rattles.
The three diameters
Every basket in this series shares them. They are quoted from the manufacturer pages cited on the individual entries below, not hand-entered here.
| Measurement | Figure | What it decides |
|---|---|---|
| Border Ø | 62.5 mm | Whether the basket seats in the portafilter |
| Body Ø | 54 mm | Whether it drops in at all |
| Tamper Ø | 53 mm | Which tamper you need |
If those three numbers being different is a surprise, that is the single most useful thing to understand about basket fitment — see why “58mm” isn’t one standard.

Dose figures vary by roast level and are published per basket rather than per series, so they live on the individual entries — each one quotes the manufacturer’s own capacity table with the date it was read.

Cross-references follow the manufacturer’s own compatibility list rather than size logic, so a machine of the right diameter is not listed unless the source names it. Sizes covered: 54mm.
