Normcore 58mm Convex Basket Kit, 22g, 58-32mm, 0.18mm Low Flow | Step-Down Basket Design, 1473 Droplet Holes, Low-Flow Extraction Control, Puck Screen Included, 200 Paper Filters

The Normcore 58mm Convex Portafilter Basket Kit is designed for baristas who want greater control over espresso flow, resistance, and extraction style.Built with a step-down internal geometry from 58mm to Ø32mm, this basket helps create a deeper coffee puck and a more concentrated extraction path. Unlike traditional baskets that often rely mainly on very fine grind settings to build resistance, the Convex Basket uses its internal shape to support a controlled low-flow extraction.With a 22g capacity and 1473 precision droplet-shaped holes, the 0.18mm low-flow structure helps promote slower, more even flow through the puck. This design supports cleaner extraction, improved sweetness, greater clarity, and a smoother mouthfeel.CNC-machined from solid 304 stainless steel, the basket offers a rigid structure, precise internal shaping, and long-lasting durability. It is ideal for espresso users exploring low-flow recipes, coarser grind settings, and more intentional extraction control.Set Includes:1 × 58mm Convex Portafilter Basket1 × 0.8mm Puck Screen200 × Espresso Paper FiltersNote:Ø32mm refers to the internal extraction area, not the outer basket diameter. Actual capacity may vary depending on roast level, grind size, humidity, and puck preparation.

• STEP-DOWN CONVEX BASKET DESIGN – Designed with a narrowed internal extraction area that steps down from 58mm to Ø32mm, this basket helps create a deeper coffee puck and a more controlled low-flow extraction style
• GEOMETRY-DRIVEN EXTRACTION RESISTANCE – Unlike traditional baskets that often rely on a very fine grind to build resistance, the convex internal geometry helps slow flow through basket shape, allowing more flexibility when dialing in espresso
