Normcore 54mm Convex Billet Basket for Breville, 5432mm, 0.28mm Holes

The Normcore 54mm Convex Billet Portafilter Basket Kit is designed for baristas who want to explore a different style of espresso extraction.Instead of relying only on finer grind settings to create resistance, this basket uses a stepdown convex internal geometry to form a deeper coffee puck and a narrower 32mm extraction area. This helps support a controlled lowflow extraction style while allowing more flexibility with grind size.The result is a basket designed for users looking for more sweetness, clarity, balance, and a smoother mouthfeel in their espresso workflow.CNCmachined from a solid block of 304 stainless steel, the basket offers a rigid structure, precise internal shaping, and a distinctive brewing experience compared with standard stamped baskets.Combined with Normcores 0.18mm dropletshaped hole pattern, it is built for consistency, repeatability, and advanced espresso experimentation.The Includes:1 Convex Billet Portafilter Basket
