The single-basket (1-cup) member of IMS’s B62 54mm Breville/Sage-format
competition series — the shallower, lower-dose counterpart to the 2-cup
B62.52TH24E. IMS states its body is “Ø 54 mm Internal” with a “Ø 62.5 mm”
border and a Ø 53/53.4 mm tamper, so it seats in the same 54mm Breville
portafilters and is cross-referenced to the nine 54mm Breville machines whose
official pages state a 54mm portafilter. At 8–12.5 g it suits single shots and
lighter doses; it does not fit Breville’s 58mm machines (Dual Boiler, Oracle,
Oracle Touch) or any standard 58mm machine. Ridgeless with electropolished,
conical holes like the rest of the competition line. Verified against IMS’s
official product page on 2026-07-13.

https://imsfiltri.com/prodotto/b62-51th23e/(archived) — Official IMS Filtri product page, read firsthand 2026-07-13. Specs verbatim: 'Border: Ø 62.5 mm', 'Body: Ø 54 mm Internal', 'Height: 23 mm', 1 cup, capacity 'Dark Roasted 8/10 gr / Medium Roasted 9/11 gr / Light Roasted 10/12.5 gr', tamper 'Ø 53/53.4 mm', '253 E' holes of Ø '0.30 mm (Circular with Conical cross section)', 'Ridgeless'. 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.
