Dado Sets

Industrial stacked dado sets for cabinet shops, millwork production, and serious woodworkers. Every dado set we stock is a true stacked design — two outside blades, full-body carbide chippers, and shims — engineered to leave dead-flat dado bottoms with minimal tear-out in solid wood, plywood, MDF, and melamine.

The dado sets we carry

We don't sell budget wobble dadoes or imported stamped chippers. Every set on this page is built for daily use in production environments.

  • LORNA Industrial Super Stack — our flagship dado set. Manufactured in Germany by Walter with first-class steel saw bodies, premium carbide tips, and CNC-ground geometry. The 8" Super Stack produces 20 different cut widths from 1/4" to 29/32" — including dedicated combos for undersized 1/2" (15/32") and 3/4" (23/32") plywood, with brass shims for fine-tuning.
  • Popular Tools DA Series — long-running industry-standard dado sets. Available in 6", 8", 10", and 12" diameters, in positive and negative hook geometries, in 5/8" and 1" bore options. The Popular Tools DA840 and DA1040 are the workhorses of countless cabinet shops.
  • Replacement components — for shops that already own a Popular Tools dado set, we stock replacement outside blades (CFP series) and replacement chippers in matching diameters, kerfs, and bores.

How to choose the right dado set

Three decisions drive the purchase:

1. Diameter — 6", 8", 10", or 12"

  • 6" dado sets: lighter, less HP required, max cut depth around 1-1/2". Good for benchtop saws and lower-power contractor saws.
  • 8" dado sets: the cabinet-shop standard. Max cut depth around 2". Most production shops run 8".
  • 10" dado sets: industrial standard for higher-HP machines. Deeper cuts, requires longer arbor.
  • 12" dado sets: heavy industrial only — large sliding table saws and high-capacity equipment.

2. Tooth count and geometry

40-tooth outside blades with matched right/left-hand grinds produce the cleanest shoulders — best for cabinet-grade work in plywood and melamine. 24-tooth outside blades cut faster, ideal for production speed when shoulder finish is less critical. Negative-hook variants are essential for radial arm saws, sliding compound miter saws, and melamine cutting.

3. Plywood compatibility

Modern plywood is undersized — a "3/4 inch" sheet is actually 23/32", and a "1/2 inch" sheet is 15/32". A quality dado set includes dedicated chipper combinations for these undersized cuts so your shelves and dividers fit snug without shim-stack guesswork. The LORNA Super Stack is engineered specifically with these combos.

LORNA Super Stack vs. Popular Tools DA Series

The most common comparison customers ask about. Both are industrial-grade. They fit different jobs:

  • LORNA Super Stack — 42-tooth outside blades, 6-piece chipper stack, brass shims, 20 dedicated cut widths from 1/4" to 29/32" including undersized plywood combos. The premium pick when finish quality and plywood-fit precision matter most. View the Super Stack →
  • Popular Tools DA Series — 40-tooth (or 24-tooth on DA824) outside blades with full-body or 2-wing chippers depending on model. Available across 6", 8", 10", and 12" diameters, in positive and negative hook, in 5/8" and 1" bores. The most flexible catalog when you need a specific diameter and bore combination.

Compatibility — will a dado set fit your saw?

  • Horsepower: 1-1/2 HP minimum for an 8" dado under load. Less than that, consider a 6" set or expect to make multiple shallow passes.
  • Arbor: Standard arbor is 5/8" on most full-size table saws; industrial saws often use 1". The arbor also has to be long enough to accept the full stack plus the nut — most saws sold as "dado-capable" already meet this.
  • Removable splitter/guard: Required, since the factory guard is sized for a 1/8" kerf, not a 3/4" dado.
  • ⚠ SawStop owners: Standard industrial dado sets are NOT compatible with SawStop machines. SawStop maintains an approved list — buy from that list if you own a SawStop.

Need a custom bore size or pinhole pattern?

Popular Tools dado sets and components can be modified to your machine's exact spindle configuration in 1-3 business days. LORNA dado sets can be modified in about 5 business days. Custom bores, pinhole drive patterns, keyways, and split blades are all handled by Popular Tools' machine shop using wire EDM, precision lathes, and mills. Learn more about custom modifications →

What's the right dado set really cost?

The purchase price isn't the right number. A premium dado set that survives 10-15 sharpening cycles delivers dramatically lower cost per cut than a budget alternative that retires after 3-4 cycles. For production shops, the math becomes obvious within a year. Read our full cost-per-cut breakdown →

What's included in every dado set we sell

  • Two matched outside blades (right-hand and left-hand)
  • Full-body carbide chippers (or 2-wing on DA824) in multiple kerf widths
  • Shim set (brass on LORNA Super Stack sets)
  • Stack chart and setup instructions
  • Storage box

Best applications

Cabinet dadoes and grooves, drawer-slide channels, shelf inserts for plywood and melamine, rabbets, tenons, half-laps, and box joints in hardwood, softwood, plywood, MDF, and melamine.

Longevity & service life

Every dado set we sell uses re-sharpenable carbide tips. LORNA Super Stack blades hold 10-15 sharpening cycles; Popular Tools DA series blades hold a similar number. A well-maintained industrial dado set will outlast a hobbyist's woodworking career and a production shop's decade of daily use.

Frequently asked questions

Stacked dado vs wobble dado — which is better?
Stacked dado sets every time. Wobble dadoes use a single blade tilted at an angle and leave a slightly curved bottom (a "smile" in the dado floor). Stacked sets cut a flat, true bottom of consistent depth across the entire width.

Can I use a dado set on a SawStop?
Not the dado sets on this page. SawStop machines require their own approved cartridge and a specific list of approved dado blades. If you own a SawStop, buy from SawStop's approved list.

What's the widest dado I can cut in one pass?
Depends on the set. Our 8" LORNA Super Stack cuts up to 29/32" in a single pass. The Popular Tools DA Series typically caps around 13/16" depending on chipper count.

Do I need a dado throat plate?
Yes. Most table saws ship with a standard throat plate that won't accommodate a dado stack. Order or make a zero-clearance dado insert for your specific saw.

How long does shipping take?
Every in-stock order ships the same business day.

Are these blades re-sharpenable?
Yes — all of them. Premium dado sets survive 10-15 sharpening cycles before retirement. That sharpening capacity is one of the major drivers of long-term dado set economics.
