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 20g-class basket in IMS’s 54mm competition line. At 26mm deep it takes 17–19.5g of a dark roast and 18–21g of a medium — noticeably more than the 14–17g the standard 24mm B62 is rated for, and the natural choice if you have moved past Breville’s stock dosing.

IMS describes the perforation on this one explicitly as “Competition Perforation: Relaminated and Recalibrated” — the recalibration step is what separates the competition line from IMS’s standard baskets, tightening the tolerance on all 583 holes so flow stays even across the puck rather than running fast in patches.

Otherwise the familiar B62 geometry: Ø62.5mm border, Ø54mm internal body, ridgeless, 0.30mm holes over a Ø44mm perforated area, Ø53/53.4mm tamper.

Choosing between heights is a dose question, not a quality one — see the 22mm, 24mm and 28mm variants.

IMS names Breville/Sage on this product page, and each cross-referenced machine below states a 54mm portafilter on its own manufacturer page.
