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 26mm Nanotech-coated 54mm basket — 17–19.5 g for a dark roast, up to 20.5 g for a light one. This is a high-dose basket by 54mm standards, and worth a check against your machine before you buy.

Check your headroom first

54mm groups have less space above the puck than commercial 58mm groups do. A 26mm basket carrying 19 g builds a tall bed, and on some 54mm machines the wet puck can end up touching the shower screen — which is not damaging, but it does mean you are past the dose the machine was designed around. If you have not already pushed past ~17 g comfortably in the 24mm, start there instead.

What the coating does

The Nanotech quartz surface is described by IMS as ‘Anti-adherent, easy to clean, antibacterial’ — the puck releases without leaving a skin, and oils do not polymerise onto the wall. It is purely a surface treatment: IMS lists the coated and uncoated versions on one capacity row, B62.52TH26E/NT, so dose behaviour is identical to the plain E basket.

Geometry is the standard B62.5: Ø62.5mm border, Ø54mm body, ridgeless, 583 hexagonal holes of 0.30mm over a Ø44mm perforated area, with the narrowing at the base that IMS uses to keep the puck compact at the bottom.
