IMS’s B62-series competition basket is the 54mm (Breville/Sage format)
counterpart to its 58mm B70/B68 baskets. IMS states its body is “Ø 54 mm
Internal” with a “Ø 62.5 mm” border and a Ø 53/53.4 mm tamper — the 54mm
seat and 53.3mm tamper that define the Breville home-machine standard — so it
is cross-referenced to the nine 54mm Breville machines whose official pages
state a 54mm portafilter. It does not fit Breville’s 58mm machines (Dual
Boiler, Oracle, Oracle Touch) or any standard 58mm machine; those take the
B70/B68 family instead. Like all IMS competition baskets it is ridgeless with
electropolished, conical holes; IMS notes the competition basket sits slightly
tighter in the portafilter than a stock basket. Verified against IMS’s

https://imsfiltri.com/prodotto/b62-52th24e/(archived) — Official IMS Filtri product page, read firsthand 2026-07-13. Specs verbatim: 'Border: Ø 62.5 mm', 'Body: Ø 54 mm Internal', 'Height: 24 mm', 2 cups, capacity '14/17 gr' (dark roast) to '17.5/20 gr' (light roast), tamper 'Ø 53/53.4 mm', '583 E holes' of Ø 0.30 mm, with 'a narrowing at the base', part of IMS's Competition Series. IMS's readable product page does not name the machine brands; the 54mm cross-references below follow from IMS's stated 'Body: Ø 54 mm Internal' (the seating dimension of a 54mm portafilter) combined with each Breville machine's own official page stating a 54mm portafilter — the same chain used for the Breville OEM 54mm portafilter entry.
