Stacked Dado Blade Sets & Flat Top Saw Blades for Table Saw Dadoing

A stacked dado set is the most versatile way to cut flat-bottomed dadoes, rabbets, and grooves on the table saw. Unlike wobble dado blades, stacked sets use multiple flat-tooth outer blades and interchangeable chippers to dial in an exact dado width without leaving a scalloped bottom. Infinity Tools offers the Dadonator stacked dado system in multiple configurations for woodworkers who require precision-fit dadoes for shelving, drawer boxes, and cabinet carcasses.

The Dadonator XL 8-inch Stacked Dado Set is the flagship configuration, offering a wide range of dado widths from the stack in a 5/8-inch arbor bore that fits most North American table saws. The standard Dadonator Set provides the core setup for everyday dado work at a more accessible price point.

Flat Top Saw Blades for Precise Groove Cutting

Flat top grind (FTG) blades leave a perfectly flat groove bottom, making them the correct choice for cutting tongues, tenons, and sliding dovetail shoulders where a sharp, square shoulder matters. The 8-inch Flat Top Dado Saw Blade is used as the outer blade in a stacked dado setup or alone for single-pass grooves and rabbets. The 4-piece Thick Kerf Flat Top Saw Blade Package provides a complete set of outer blades and chippers for the widest dado widths.

Frequently Asked Questions

What is a stacked dado blade set?

A stacked dado set consists of two outer saw blades and a set of interchangeable chipper blades that are combined on the table saw arbor. By stacking different numbers and thicknesses of chippers between the outer blades, you can dial in a wide range of exact dado widths.

What is the difference between the Dadonator and the Dadonator XL?

The Dadonator XL is the expanded configuration offering a wider range of dado widths and additional chippers. The standard Dadonator provides the core setup for the most common dado widths at a lower cost.

What does a flat top grind saw blade do differently?

A flat top grind (FTG) blade has teeth ground flat across the top rather than alternating bevel. This produces a perfectly flat groove or rabbet bottom with square shoulders — important for joinery where a beveled or rounded bottom would affect fit.

Can the Dadonator dado set be used on a 10-inch table saw?

Yes. The Dadonator sets are 8-inch diameter with a 5/8-inch arbor bore, which is compatible with most 10-inch table saws that accept an 8-inch dado stack. Confirm your saw's throat plate clearance and arbor length before ordering.

How wide of a dado can the Dadonator set cut?

The maximum dado width depends on the specific Dadonator configuration and how many chippers are included. The Dadonator Master Package provides the widest range of widths. Contact the Infinity Tools team for specific width increments.

What arbor bore size do these dado sets require?

All Dadonator sets in this collection use a 5/8-inch arbor bore, which is the standard size for North American table saws. Confirm your saw's arbor diameter before purchase.

Can I use a stacked dado set to cut box joints?

Yes. A stacked dado set can cut box joints by setting the dado width to match the joint pin width and using a box joint jig to index the workpiece. This is a common technique for drawer boxes and decorative joinery.

What is the Dadonator Master Dado Package?

The Dadonator Master Package is the most complete configuration of the Dadonator system, including additional chippers and shims for the full range of dado widths achievable with the set.

Does Infinity Tools guarantee its dado sets?

Yes. The Dadonator dado sets are covered by the Infinity Tools quality guarantee. See the page for full coverage details and how to file a claim.

How do I set up a stacked dado set on a table saw?

Mount the outer blades on the arbor, add chippers between them to reach your target width, and use thin shim washers to fine-tune the width if needed. Always use a dado throat plate and check that the stack clears the blade guard and splitter before cutting. The Infinity Tools Learning Center has a complete dado setup guide.
