Normcore 58mm Convex Billet Portafilter Basket, 58-32mm, 0.18mm Holes, 22g

Why it's a great deal

• 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

• BUILDS RESISTANCE THROUGH GEOMETRY – Unlike traditional baskets that often require a very fine grind to build resistance, the convex internal geometry helps slow flow through basket shape, supporting a cleaner and more balanced espresso profile

• 0.18MM PRECISION HOLE STRUCTURE – Features Normcore’s droplet-shaped 0.18mm hole design to help promote even flow, stable extraction, and refined espresso clarity. Ideal for users exploring low-flow or high-control espresso recipes

• CNC-MACHINED FROM SOLID 304 STAINLESS STEEL – Machined from a solid billet of 304 stainless steel for durability, structural consistency, and a precise internal profile that differs from conventional stamped baskets

• IMPORTANT FIT NOTICE – Due to the deeper convex step-down shape, this basket is recommended for compatible 58mm bottomless or naked portafilters only. Please verify portafilter depth and machine clearance before purchase

• 22G LOW-FLOW CONVEX BASKET – Designed with a 58mm to Ø32mm step-down internal geometry, this basket creates a deeper coffee puck and supports a controlled low-flow extraction style. Approx. 22g capacity
