Cross-section to scale, from the dimensions IMS publishes for this basket. The border is what seats in the portafilter — not the tamper figure the size is usually quoted by. See why “58mm” isn’t one standard.

That model name is an IMS product code — series, cup count, height and hole pattern are all encoded in it. IMS basket codes, decoded explains how to read one, and lists every code covered here.

This basket is one of a line. See every IMS B62.5 Competition basket compared — the whole ladder of heights and variants on one page, with the three diameters they share.

Fits these machines

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.
