Overview
Brazilian Chestnut, also known as Sucupira, is a dense South American hardwood that behaves like it has a personal vendetta against dull tooling. Some sources indicate it can be difficult to work because of its high density and irregular grain, so pre-boring and patience are part of the deal. Brazilian Chestnut is photosensitive, and will likely darken over time. It’s also rated very durable, which is why it shows up in high-wear applications. Treat it like a specialty flooring and heavy-duty furniture wood, not a weekend craft board.

Shop Notes / Deeper Dive
Brazilian Chestnut (Sucupira) is a tough-as-nails Brazilian import that demands a sharp edge and a slow feed rate. It’s got a coarse texture that likes to fight back, so break it down in stages and give it time to rest between cuts. It’s perfect for heavy-duty furniture, provided you use floating panels to let it breathe through the seasons.
