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 deepest basket in IMS’s Nanotech-coated 54mm line at 28mm, rated 18–22 g for a dark roast and up to 23 g for a light one. That is a 58mm-sized dose in a 54mm basket, and it is a specialist choice rather than a default.

Who this is actually for

Two situations justify it. The first is a bottomless portafilter on a 54mm machine, where you have swapped the stock spouted holder and want to run the doses a 58mm setup would. The second is light-roast recipes, where the same volume of coffee weighs less and a 22 mm basket runs out of room before you run out of dose.

If neither applies, the 22mm or 24mm will fill properly at the dose you are already pulling. A deep basket run at a small dose is worse than a shallow one, not better: the puck sits low with a large void above it, and that void is where the water goes first.

The coating

‘Anti-adherent, easy to clean, antibacterial’ in IMS’s words — a quartz surface over the standard B62.5 geometry: Ø62.5mm border, Ø54mm body, ridgeless, 583 hexagonal holes of 0.30mm across a Ø44mm perforated area. IMS publishes the coated and uncoated versions on a shared capacity row (B62.52TH28E/NT), so the coating buys cleaning, not extraction.
