IMS 58 mm Precision Basket – 17/19 g, H24.5, Ridged (B70 2T H24.5 M)

IMS B70 2T H24.5 M precision basket

This IMS basket is engraved B70 2T H24.5 M, meaning a 70 mm rim, two-cup capacity, 24.5 mm height and micro hole spacing. It takes 17 to 19 g of coffee and fits a 58 mm tamper. Average capacity sits around 18 g, a common café double.

Hole pattern and shape

The perforated area is 44 mm wide and holds 641 circular holes of 0.30 mm with a conical cross-section, set 1.5 mm apart. Its cylindrical body has a specific corner radius at the base, which IMS shaped to use the whole puck and make knocking out easier. An external ridge of 60.5 mm holds it in sprung portafilters.
