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 B70 Competition basket compared — the whole ladder of heights and variants on one page, with the three diameters they share.

Fits these machines

The NanoQuartz-coated version of IMS’s B70 2-cup competition basket — a flat (H24) profile with the same Ø70 border and 58/58.4mm tamper fit as the rest of the B70 line, but finished in IMS’s Nanoquartz coating for “high non-stick properties” and “corrosion resistance”. The non-stick surface makes for cleaner puck release and easier wiping; the shot geometry is the familiar B70 — 715 holes of 0.30mm in a hexagonal pattern, a 16–18g dose for a dark roast rising to 17–19g for a light one.

It carries the same B70 compatibility as the other entries in this series: any E61 or 58/58.4mm-tamper machine on IMS’s competition list — La Marzocco, Rancilio, Lelit, Rocket, ECM and the Breville Oracle. Gaggia machines take the narrower B68 series, not B70, so they are deliberately not cross-referenced here. Verified against IMS’s official product page and Competition catalogue.
