This John Boos CCB Series cutting board is a 3-inch-thick round maple block, 18 inches in diameter, sized to anchor a prep area or sit at the center of a kitchen island as a dedicated chopping surface.
An 18-inch round board occupies a different role than a rectangular slab. The shape is natural for working around a center point, whether that means rotating through a pile of vegetables, carving a roast, or setting up a butcher-station feel on a round kitchen island. At 3 inches thick, the block carries enough weight to stay planted without a damp cloth underneath, and the surface area gives a cook room to work without the board feeling cramped. It also reads well as a dedicated prep station sitting on a countertop, where the round form keeps the workspace defined rather than spreading into adjacent prep areas.
John Boos has built cutting surfaces from Northern hard rock maple for well over a century, and the CCB Series continues that practice. Hard rock maple is a dense, close-grained hardwood chosen specifically because it resists scoring and absorbs fewer juices than softer woods, which extends the board's working life and keeps the surface cleaner between washes. The 3-inch thickness means there is material to resurface over time if the top develops deep score lines. For conditioning and long-term care, a food-safe board oil finish is the standard maintenance practice for maple blocks; John Boos recommends their own Mystery Oil or Board Cream, though the source does not specify a pre-applied finish on this SKU.
This board is a practical choice for a home cook who wants professional-grade prep equipment without a custom countertop installation. It suits kitchen designers specifying a movable prep surface for a client's island, and it works in a small culinary studio or demonstration kitchen where a round, self-contained prep block communicates craftsmanship. The 18-inch diameter is large enough for real production work but compact enough to store on a counter or in a deep base cabinet when not in use. For shops building custom kitchen packages, it pairs naturally with a butcher-block or hardwood countertop specification.
A round board is easier to rotate mid-task, which helps when working around a center piece, carving, or organizing a prep flow that moves in a circle. On a round island or pedestal, it also fits the shape of the surface better than a rectangular board with corners hanging over the edge.
The source does not specify a pre-applied finish on this SKU. Condition a new maple block with a food-safe board oil before first use and repeat as needed to maintain the surface and prevent drying or cracking.
Yes. At 3 inches thick, the block has enough material depth to be sanded or planed flat and re-oiled, which extends its useful life well beyond what a thinner board allows.
John Boos is a long-established professional kitchen supplier and the CCB Series is designed for serious prep use, but confirm any sanitation or health-code requirements for your specific commercial setting before specifying this board for a commercial installation.
Choose this 18-inch round maple block when the prep station calls for a thick, resurfaceable hardwood surface that earns its place at the center of the kitchen.
