Enhance the quality of your dadoes with Freud's SD508 Eight-Inch Super Dado Set with Anti-Kickback Design. Designed to produce smooth, chip-free dadoes and grooves every time, this set is designed to take on a wide range of materials, from hardwoods to laminates. For exceptional precision, the blade width can be adjusted in 1/32-inch increments, while the included shim set allows for even finer adjustments.

Razor-Sharp Blades for Smooth, Splinter-Free Dadoes
The perfect dado set for the fine cabinetmaker or weekend woodworker, the Freud SD508 produces dadoes and grooves that meet with flush, even edges. So you can be assured of precise cuts every time, the set is equipped with precision-grade features, starting with two proprietary razor-sharp outside blades.

These high-quality eight-inch, 24-tooth blades with 5/8-inch arbors cut dadoes and grooves that are clean, flat, and virtually splinter free. Cuts made by these blades are accurate the first time, saving you from making repeated passes over the same workpiece.

Flexibility for Cutting Hardwoods, Veneers, and More
The Freud SD508 fits all table saws and radial-arm saws and accommodates a wide range of materials, so you can keep it on hand from project to project. Use it to create dadoes and grooves in hardwood, softwood, chip board, plywood, and laminate (not recommended for non-ferrous materials).

Adjustable Dado and Shim Set for Achieving Perfect Width
Producing the perfect dado is often reliant upon finding the perfect blade width. Designed with that mind, this set virtually doubles the number of slot widths available. First, its adjustable dado allows exceptionally fine-tuned adjustments in 1/32-inch increments. It also features a handy shim set for those jobs that call for even finer blade-width adjustments.

And for greater versatility, the set's six chippers include a unique 3/32-inch chipper along with four 1/8-inch chippers and one 1/16-inch chipper. These chippers' four-wing design is a step above the common two-wing design of most chippers. This means your chippers will work efficiently to remove waste material and smooth the edges of your work pieces.

Anti-Kickback Design for Safe Operation
The quality of this dado set is enhanced by its anti-kickback design, which gives you an added margin of safety while you work.

MicroGrain Carbide Tips for Long-Lasting Performance
So you can get maximum performance out of this set, the blade components are constructed with Freud's TiCo Hi-Density Carbide. This means the blades can withstand numerous sharpenings and still retain their superior precision. And a Tri-metal Brazing process gives the blades impact resistance, so they last for the long term without dulling (a condition that can cause torn wood and uneven cuts).

What's in the Box
Freud SD508 Eight-Inch Super Dado Set with Anti-Kickback Design, including two eight-inch blades (with 5/8-inch arbors), shim set, four 1/8-inch chippers, one 3/32-inch chipper, and one 1/16-inch chipper.
From the Manufacturer

Chip Free Dadoes in Veneered Plywoods and Laminates
The SD500 Series dadoes were the first dadoes to include a 3/32 inch thick chipper. This allows the cut width to be adjusted in 1/32-inch increments and doubles the number of slot widths available. Many plywoods are being manufactured 1/32-inch undersized from the nominal size and this allows you to cut dadoes that will fit these materials with less shimming. We have also included a shim set with the dado for fine adjustments.
Freud's new Square Tooth(tm) design utilizes a shorter and thicker tooth which reduces drag in the cut and reduces the materials guiding effect. The Square Tooth(tm) design also increases the number of sharpenings you can obtain.
The SD500's use an extra thick and stiff outside plate, eliminating the hub. The gullet design provides maximum chip ejection. Both of these features prevent chip buildup within the stack.

Use on all tablesaws, and radial arm saws for cutting slots, grooves, dadoes, and rabbets in softwood, or hardwood.
Caution Carbide tips should never come into contact with each other. Always use both outside blades and never use chippers alone or with just one outside blade.

Fine Freud Dado blade

Review Summary

I've owned and used this dado blade for probably close to twenty years now and it has performed very well for me. It cuts nice smooth flat bottom dado's with no chip out in Plywood and even melamine board. The only thing I don't like about this set is the shim set that comes with it. The shims aren't magnetic and do have a tendency to fall down into the screw threads and get smashed, which also creates and uneven set up, so you have to be careful when setting these.
And of course it can only remain this good if you find the right sharpening service who will sharpen these properly. Don't just trust it to any old jack sharpener. Find some one who really knows how to sharpen these. I love the storage chase this blade comes in as it's compact and allows you to store and transport the set without any damage.
