Oshlun SDS-0842 8-Inch 42 Tooth Stack Dado Set with 5/8-Inch Arbor

I have turned some very expensive wood into sawdust and regret. Surely with this tool I can do so at a much faster pace. I have never used a stack dado set before but some would-be-wood-worker-guys on YouTube make it look pretty easy, and most of them have their fingers. So how hard can it be? I threw away the instructions ‘cause, who needs those? When you have 3lbs of steel spinning at 6,000 rpm who cares about that? The center hole for the arbor is extremely close tolerance (and for good reason) which made installation and removal a bit challenging but when installed, very very secure. The instructions indicate the blade stack and shims are “under rated” or “under sized” to accommodate the nominal thickness of various woods. So I took them at face value and installed the 3/4” setup. Now, let me be clear, I have NEVER used a dado set before. I took out my calipers and measured the stack installed and tightened. Just short of .75” as promised. So far so good. Used a square to measure cut depth. So far so good. Set up the fence to center the cut at 4” from the desired edge. So far so good. With nervous anticipation green button, on. Soft start up, check. Dust collection, on. All seems to be going to plan. No noises. No vibrations. No issues. Time to put the wood to it! The cut quality was PERFECT! No tear out, no truly discernable ridges in the cut. The chippers made relatively clean cuts the whole distance. My first dado cut was 25” of pure success. The fitment of the dado was near perfect as far as I could tell. I glued it up, threw in a screw or four and all is well. I wiped the blades down as they had plenty of oil to protect them. The shipping/storage box is not pretty but adequate to protect them. Would recommend to anyone needing the occasional dado cut.

Product was shipped and delivered promptly after order was placed. The blade set I received was in the aluminum case with heavy foam support around perimeter and foam sheets in between all blades. I am a weekend hobby woodworker and never used dado blades before the purchase. These work great for me! All the blades and shims in my set came clearly marked and I found it easy to make slight adjustments and dial in the exact width of cut I needed. I have a 15+ yr old JET JWTS series contractor saw and the blades and shims went on and off my factory 5/8" arbor with no problems. I will say that the shims can be a little tricky as they tend to find their way down into the arbor threads so be careful with that. All the blade teeth were complete and sharp (no nicks or quality issues as some other reviewers have cited). I have used once so far making many dado slots in MDF. The cuts were clean with a smooth, flat bottom. As the manufacturer clearly explains in the included literature the outer blade teeth are angled and slightly deeper intentionally to cut a crisp clean edge and bottom with minimal tearout. The minimal bottom corner groove produced by the outer blade teeth is barely noticeable and not a concern for me. Another positive for me was the full chipper blade design. I was down to this set or the similarly priced set from Freud. I had read a few reviews that indicated the partial chipper blades in the Fred set were not so easy to align and hold in place when installing on the arbor. That was a key factor in my choice of the Oshlun set. I have to say that even with the full chipper blades, aligning multiple blades for wider cuts can be tedious, especially if you need to use a few shims. I am very glad I went with the Oshlun in that regard because I understand now how much more difficult it would likely be with partial blades. Overall I am 100% happy with my purchase and I highly recommend to anyone considering.

Have been debating purchasing this dado stack for a while. Have a premium other dado that wasn’t giving crisp dados, in all fairness it’s over 20 years old and several resharpenings. I stacked the Oshlun to .750 and ran a.375 dado along and across the grain of veneered plywood and was amazed at the quality of the cut. The bottom was square and flat with zero tear out. Where the cut crossed was invisible except for minute bat wing. Well exceeded what I expected for that price.

I have owned a couple dado sets over the past 10 years....an ultra-cheap Mibro set from Lowe's and the Freud Professional black set. Each cost under $100 and each worked fine for what I intended. But, when they dull past being useful, it is not really economical to have the whole set sharpened...it is time to invest that $75 in new...the American way, after all. While I would love to drop $250 on the Forrest Dado King, I was really not in the market for that kind of investment. I have other Forrest blades and could not be happier with their performance, and the rehab and sharpening service available from them, so I am sure the Dado King is a superior option...and should be for the price. Which brings me to the compromise of the Oshlun. I looked at a new Freud set, but to be honest I wasn't particularly happy with the Freud...I found set up with the winged chippers to be difficult as you have to be picky about staggering the cutting edges and balancing the pack with one hand while threading the arbor nut with the other hand. If all this did not come off well, the stack would not tighten correctly on the arbor and be off balance and untrue...if there were shims involved, it was even more tedious. As a consequence, I decided on this Oshlun set for $10 less than the Freud...all the bargain priced sets are made in China, anyway. The nearly full plate chippers, additional teeth and the 3/32" chipper were the attractions...as well as the price. I was stunned at the weight of the box upon arrival...those full plate chippers add lots of hefty iron to the set. I inspected all the blades...which all the parts were in the box as promised ...all the teeth were present and sharp...all the plates were flat and warp free. The set comes packaged in a handled box with die-cut foam between the blades...no doubt to protect on the long voyage out of Nanking. The box will quickly become worthless for storing the set (the Freud comes with their ubiquitous red plastic, two-sided storage case...nice, but doesn't make up for the tedium of winged chippers) so I fixed a 1/2" carraige bolt to a plywood scrap and saved some die-cut foam to cushion the all important cutting edges....then pitched the box and the rest. Today, I mounted 3/4" of plates and chippers and plowed dados in some plywood clamping cauls....they came out crisp and clean with nary a fuzzy edge or chip out and a dead flat bottom...then I cut 1/2" box joints in some tough white oak scraps to perfect a set up for a planned project...again the set performed well making crisp edged joints in the oak and flat bottoms. The set up was easier with the full chippers, which seat nicely against each other and the set ran noticeably quieter and smoother than the Freud. I'm satisfied with the purchase...all the parts were in the box, all the edges were sharp, all the saw plates were flat and true, the cutting edges lined up perfectly on the arc resulting in flat bottoms...I can't honestly ask for much more from 25 lbs. of Chinese iron and carbide, so my compromise is satisfactory.

Ignore the comments about the packaging, The set I just received could not be packaged more carefully. It comes in a nicely made aluminum and plastic case with a handle and latch, Inside, the chippers are nested in high-density foam cut to their exact shape, except for a slot to get your finger in, and foam leaves, also cut to their shape, sandwiched in between. Another high-density foam insert lays on top of the chipper insert to allow for the larger outside blades, which are also separated by foam leaves. Perched on top are clear directions with excellent safety advice (e.g. leave the outside flange off on large widths if you are not showing at least three arbor threads after tightening) and a ziplock bag of laser etched shims that would make a gap gauge jealous. My arbor is plenty long to handle the full set. I inspected all of the blades and found everything in order: no chipped carbide, no bad brazing, no signs of use. Despite the lack of awful smelling machine oil that usually coats new steel bits and blades, everything was clean and rust-free. I built a finger (box) joint jig and was able to dial in a perfect fit for one-by stock with three of the included shims. I learned the hard way how sharp the carbide tips are when I tried to adjust one of the chippers and pushed a tip right through my thumb nail. With 42 tips on the blades, you have to be careful not to stack chipper tips against them. Balancing the chippers is a breeze with six tips each. The cuts are smooth as a baby's butt and the anti-tear-out bat ears are imperceptible. Because of the six-tip chippers, this is a heavy set. My cheapo Delta floor table saw gives out a screech when it starts up but it cuts red oak with ease. Despite the anti-kickback angles of the blade tips, it still kicks back if you try to rip too deep. I thought, "if it can cut a 3/4" box cut through oak with ease, why not a 3/4" deep rabbet. Fearing for my life after two tentative pushes, I dialed down the depth and the rabbet came out perfect in two passes, leaving only a 1/16 strip intact

I'm just a hobbyist woodworker, but I prefer quality tools - especially if they aren't too expensive. This dado set fits that description perfectly. Smooth, clean, flat bottom dados with no tear out. My first project with this set was in red oak, and I don't know how the set could have performed any better. Years ago, I bought an adjustable dado set - two blades mounted on a center hub that would let you tilt the blades in or out to change the width of you dado. Total junk. Literally could not make a flat bottom due to the design. Don't know if that type of dado set is still made, but if you see one, avoid it at all costs. I selected this Oshlun set because I thought the full blade multi-tooth chippers and the high tooth count on the outside blades would give a cleaner cut than the sets with fewer teeth and wing chippers with only two teeth. Don't know if that's true, but I am completely happy with the results I got with this Oshlun set. No regrets spending the money at all. The only negative is the advertised storage / carry case is simply a cardboard box with foam cutouts. Still a 5 star product.

Update: I have now used the dado blade set and I can say without a doubt this is a really quality set of blades. I recently built a new table for my bandsaw and I included T-tracks to increase the versatility. I used the Oshlun dado set to cut T-track slots. The table top has a melamine surface which is highly prone to chipping and tear out but these dado blades sliced right through cleanly and I couldn't be happier with the performance. The blades were super easy to setup and use compared to the set they replaced. From all aspects just a really quality set of dado blades. Original review: I haven't had a chance to use these blades yet but I will soon for an upcoming project and when I do I will be back to update this review. In the meantime I can say I am really impressed by the quality of these blades, the craftsmanship seems excellent. I an attest to how sharp the blades are when, even after being very careful, I managed to get a cut but the blades are so sharp I didn't even know I had been cut until latter. The one issue I have with this dado set so far is the case which is really just a box with a plastic handle. To solve this issue I found an inexpensive case that fits the dado set perfectly (see photo).

I have a Skil table saw and not a newer model. I have a number of projects that I have wanted to do involving dado cuts. After reviewing many sites, I settled on the Oshlun stacked dado set. There were a number of reviews of Frued with trouble fitting to the arbor, I had no trouble at all with this set. Price line was another element. There are more expensive sets and lesser expensive sets. Not an Earth shattering discovery, but this one just fit my budget. I can't imagine those at twice the price being twice as good. This set comes with 2 main 8 inch blades, 6 full body 6 tooth chipper blades (4 - 1/8, 1 - 1/16, 1 - 1/32), and an assortment of shims (8) wrapped up in a cardboard carrier. Not a fancy package, but I don't do this for a living so adequate enough for me. I am a relative novice at this, but I was able to set up two different sized cuts in no time. Did a great job. Cuts were nice, no ridges, a really smooth bottom. A couple of practice cuts and your off and running. For those who are just looking to get into this, you need a saw with at least 1.5 HP better with 2.0+ HP. You also need a dado inset for your saw. It took me a while to find one for my saw. And it really wasn't advertised for this blade size, but it worked. You can attempt to make your own, but I just wanted to plug and play as soon as possible. Amazon, as always, did a nice job in delivery. A nice set. Can't say much about durability as yet. Time will tell.

I am a new wood working, and getting into some of the interesting projects. never used a dado prior to this one, and I honestly did not know what to expect. all of the previous dado's Ive done were made using my router or the single blade table saw. alot of feedback and lot options out there, however I can say, the oshlun blades came in well packaged ( cardboard box), but the blades were organized and separated by a foam like disk with the little washers for spacers. I purchased on the 8" set the cut is clean, and I say clean and not only because I havent tried other sets from other vendors, but watching many youtube videos I can see that the quality of my blades is better . accurate and true. I havent found a need to use the spacers, but I am sure I will at some point. I believe they are priced well, made well, and gave them a 5 stars because they performed flawlessly I am not sponsored by this seller nor any one else. straight shooter all around. I recommend this product.

Excelente lo que se publicó, es lo que recibí.

Bin begeistert. Bis ca. 19 mm Nutbreite kann man auf der Bosch GTS 10 XC noch die originale, mutterseitige Unterlegscheibe verwenden. Achtung! Auf eigene Gefahr! Selbstverständlich hat das Dado Set kein CE zeichen, noch ist die Bosch Säge dafür zugelassen. Die Qualität ist super, nur die Zollmaße erfordern eine Probefräsung. Bei meiner Säge wäre mit 8“ Blatt eine Nuttiefe von ca. 54 mm möglich. Auf dem Foto ist die Nut 17,6 mm breit und 20 mm tief. P.s.: so konzentriert wie bei dem Schnitt war ich schon lange nicht mehr 😜

OK, I haven't used this set yet so I can't tell you how it performs. Based on various woodworkers reviews I have no doubt it will work perfectly. The blades are heavy, clearly marked, and sharp. They have more teeth than the competition which should therefore give a cleaner cut and more balanced operation. The set was well packed for transport but comes in a cardboard box unsuitable for repetitive use so I made a tougher one with multiple slides to carry the blades. Am I happy with the purchase? Absolutely. A well made tool at a great price.
