Oshlun Tooth stack and Inch Box and Finger Joint Set Review: The 8-Inch Workhorse That Demands Patience

You know that moment when you’re halfway through a cabinet build and realize your dado stack can’t handle a 3/4-inch groove without three passes? That’s the problem the Oshlun Tooth stack and Inch Box and Finger Joint Set solves — but it introduces a few headaches of its own. With a 4.4-star average across 220 Amazon ratings, this set has a loyal following among hobbyist woodworkers and small-shop professionals. Here’s what you’re actually getting before you drop the cash.

What’s in the Box

This isn’t just a dado stack — it’s a two-in-one system. You get the 8-inch stacked dado set (two outer 24-tooth blades, four chippers, and shims) plus a separate finger joint cutter set with its own arbor spacers. The 2-inch bore with bushings means it fits both 5/8-inch and 3/4-inch table saw arbors, which covers most contractor and cabinet saws on the market. The whole thing weighs just over 6 pounds, so it’s portable enough to swap between shop and jobsite.

Real-World Performance

Mounting is straightforward: stack the chippers between the outer blades, tighten the arbor nut, and you’re cutting. The carbide tips on the outer blades are noticeably aggressive — one reviewer noted, “First cut through 3/4-inch red oak was glass-smooth, no burning even at moderate feed rate.” That’s the good news.

The bad news? The chippers are all the same tooth pattern. There’s no offset grinding on the inner cutters, which means you’ll need the included shims to dial in precise widths. For a 1/2-inch dado, you can stack two chippers and get a clean cut. But for odd sizes like 5/16-inch or 7/16-inch, you’re stacking shims and hoping the arbor threads catch enough. One buyer summed it up: “Took me 20 minutes to get a clean 5/8-inch groove because the shims are fiddly and the chippers don’t self-index.” That’s a real workflow killer if you switch widths often.

The finger joint set is a different story. It cuts clean 1/4-inch and 3/8-inch fingers in softwoods, but hardwoods like maple will tear out if your arbor has even slight runout. One reviewer warned, “Perfect on pine, but my older saw’s arbor caused chipping on walnut — you need a well-tuned saw for this to shine.”

What Buyers Love

The value proposition is undeniable. At this price point (check current pricing on Amazon), you’re getting a carbide-tipped 8-inch stack plus a finger joint set — comparable brand-name setups cost 30-50% more for just the dado stack. The cut quality on the outer blades earns consistent praise. One Amazon reviewer wrote, “Cuts cleaner than my Freud — no chip-out on plywood veneer, which I didn’t expect at this price.”

Durability also gets credit. Multiple reviewers report hundreds of linear feet of cuts without sharpening, which tracks with the carbide tips. The included wrench and wooden storage block are basic but functional.

Where It Falls Short

The shim system is the biggest frustration. It works, but it’s not elegant — you’ll spend time fiddling rather than cutting. The plastic case is also a letdown; one reviewer said, “The chippers fell out of the case twice in my truck — it’s just a tray, not a real box.” And if you’re expecting a true “box joint cutter” that does both 1/4-inch and 3/8-inch fingers with perfect alignment, the arbor requirements might surprise you. A dial indicator to check runout is almost mandatory for the finger joint function.

Who Should Buy This

• Cabinet makers and furniture builders who need a versatile dado stack for plywood and solid wood — the cut quality justifies the setup time.
• Hobbyists on a budget who want carbide durability without the premium price tag.
• Skip it if you’re a production shop that changes widths dozens of times daily — you’ll lose more time shimming than you save in cost.

FAQ

Q: Will this fit my DeWalt jobsite saw? A: Yes, if your saw has a 5/8-inch arbor. Use the included bushing. The 8-inch diameter is fine for most 10-inch table saws — just check your blade guard clearance.

Q: Does the finger joint set replace a dedicated box joint jig? A: No. It cuts the fingers, but you still need a fence system or jig to guide the workpieces. The cutters only replace the dado stack part of the equation.

Q: Can I use this on a radial arm saw? A: Technically yes, but the 8-inch diameter combined with the arbor nut length can be tight on some RAS models. Test fit before committing.

The Verdict

Buy it if you want a single set that handles dados, grooves, and finger joints with carbide durability — and you’re willing to spend a few extra minutes on setup for odd widths.

Skip it if you need precision shimming-free widths on every cut, or if your saw has known arbor runout issues.

The Oshlun Tooth stack and Inch Box and Finger Joint Set earns 4.2 stars. It’s not the fastest or most refined system, but for the price, the cut quality and versatility are hard to beat. The 220 reviewers at 4.4 stars agree: this is a solid value with a learning curve, not a plug-and-play solution.
