Normcore Convex Billet Portafilter Basket Kit

The Normcore Convex Billet Portafilter Basket Kit is precision-engineered to transform your espresso brewing experience. Unlike traditional espresso baskets that rely heavily on grind fineness to build pressure, this geometry-driven basket creates extraction resistance through its unique shape. By narrowing the internal extraction area to Ø32mm and forming a deeper coffee puck, it enables a controlled flow with coarser grind settings. The result? A sweeter, cleaner cup with enhanced clarity, perfect balance, and a remarkably smoother mouthfeel. Built for precision and consistency, this basket allows baristas to achieve a highly refined espresso profile. Key Features Geometry-Driven Resistance: Achieve an intentional extraction style without relying on excessively fine grinds, which significantly reduces unwanted fines and muddy flavors in your cup. Premium Construction: CNC-machined from a solid block of 304 stainless steel, ensuring unmatched durability, thermal stability, and consistency. Proprietary Hole Design: Features Normcore’s droplet-shaped holes, available in Low Flow (0.18mm) and Standard Flow (0.28mm) to perfectly match your brewing style. Complete Brewing Setup: Comes as a comprehensive kit including a premium puck screen and filter papers to further elevate water distribution and extraction clarity. Product Specifications Material CNC-machined Solid 304 Stainless Steel Internal Extraction Area Ø32mm Available Outer Diameters 54mm | 58mm (18g baskets) Flow Types & Hole Sizes Low Flow: 0.18mm holes | Standard Flow: 0.28mm holes What’s in the Box? 1 x Normcore Convex Billet Portafilter Basket (18g) 1 x 0.8mm Stainless Steel Puck Screen 200 x Espresso Filter Papers Usage Note: Because this basket is machined from a solid block of high-quality 304 stainless steel, magnetic dosing funnels may not stick magnetically to the rim. However, your funnel can still be placed directly on top to seamlessly guide coffee grounds into the chamber. * “Ø32mm” refers to the internal extraction area at the bottom of the basket, not the outer diameter of the portafilter compatibility. Actual dose capacity may vary slightly based on coffee bean roast level, grind size, and ambient humidity.
