Meet the Freud SD508 8" Super Dado Set — a premium stacked dado system engineered for clean, precise grooves in cabinetmaking, shelving, and general woodworking. Built for consistency and long life, this set elevates your dados beyond standard cuts with two sharp blades, a full slate of chippers, and a shim kit to dial in exact widths.

What’s in the box

• 2 blades — the core of the stack for strong, accurate cuts
• 6 chippers — provide a wide range of widths for custom joinery
• Shim set — precise spacers to fine-tune your dado-to-surface fit

Why the SD508 stands out

• Versatile, scalable widths — stack the blades, add chippers, and use the included shims to achieve a broad spectrum of dado sizes without changing blades mid-project.
• Clean, repeatable cuts — designed for smooth bottom surfaces and minimal tear-out in both hardwoods and softwoods, improving fit and finish on shelves, cabinet backs, and partitions.
• Durable, long-lasting teeth — built with Freud’s precision carbide tooling to resist wear and maintain edge integrity through many cuts.
• Time-saving setup — quick alignment and stable stacking reduce setup time, so you spend more time building rather than adjusting.
• 8" compatibility — specifically configured for 8" dado applications in common woodworking setups, making it a reliable choice for mid- to large-scale projects.

Ideal projects and use cases

• Cabinetry joinery: dado shelves, back panels, and divider slots with precise alignment.
• Furniture making: sturdy dado joints for bookcases, chests, and frames that stay square over time.
• Drawer construction: add stable bottoms and partitions with repeatable widths for a clean, professional look.
• RV, closet, and built-in installations where accurate grooves and strong joints matter.

Setup tips for best results

1. Plan the required width for your dado, then select the corresponding number of chippers and a blade combination to reach that size.
2. Install the blade stack securely and verify that all components sit flat and aligned before cutting.
3. Use the shim set to fine-tune the final width. Make a test cut on scrap wood to confirm a perfect fit.
4. To minimize tear-out, run the workpiece with a backing board and take light passes if you’re breaking in a new set.
5. Always follow your table saw’s safety guidelines and wear appropriate eye and ear protection.

With the Freud SD508 8" Super Dado Set, you gain reliable precision, flexible sizing, and a cleaner finish that takes your woodworking projects from good to pro. It’s the go-to choice for woodworkers who value exactness, durability, and efficient setup in every dado you create.
