Oshlun SBJ-0830 8-Inch Box and Finger Joint Set

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.

I was very happy with this dado set. The larger number of teeth on the outer blades make a nice clean cut. It has a nice range of dado cut widths by varying the inner cutter and spacer combinations. Blades appear to be of high quality and the price was reasonable. Packaged well for shipping and or storage too.

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

Super sharp and works fine. Still got tear out on cheap HD birch veneer plywood until I made a super shallow pass (1/16”) first to score veneer and then went back with a full depth cut. Only complaint is that one of the 1/8” width blades makes a shallower cut than the rest which leaves a slight ridge in the bottom of the dado.

This dado set is very nice. The center blades have four cutting tips which makes for less tear out of the stock and less strain on my direct drive table saw. It makes very clean cuts on soft pine, and effortless clean cuts on hardwood too. Someone mentioned in one review to be careful when handling them and/or use gloves as the blades are very sharp and can easily cut you. That is a true statement. I highly recommend these if you’re a serious and/or experienced woodworker. The quality you get against the value is great.

Muy recomendable y muy barato..lo mejor!!

My DeWalt DWE7485 does not have long enough arbor to accept dado blades and this is a major downside of this otherwise great table saw. I've searched long enough for alternative blades that have thinker kerf and flat top. There aren't many to begin with and most are expensive. Look no further. These blades are the perfect affordable solution. I only used once so far but I'm very pleased with the cuts.

Pelo valor da mercadoria, merecia uma embalagem melhor, as lâminas intermediárias vieram umas sobre as outras, dependendo do cuidado(falta dele) no transporte, pode acarretar em quebra dos dentes por atrito.Aconselho uma nova embalagem. O meu chegou bem, nenhuma avaria aparente. Resta agora testar para ver se tudo cabe na DW7492.

Works very well, especially given relatively low cost. Produces nice, smooth bottom slots with clean sides. Has very complete set of chippers and shims, permitting wide array of cut widths. Note that for most applications, there is no advantage to getting a dado stack of diameter over 6”; you rarely need to make cuts deeper than the 6” will, larger units cost more, and require much more powerful saw to work properly. Also note that on many table saws, especially contractor type, the motor mandrel may not be long enough to accommodate all the supplied chippers and shims, limiting the slot width below the max specified. You will also need to omit mandrel washer/stiffener to maximize cut width, but units works well and is safe with retaining nut alone as long as at least 3 threads visible. Also note for best results you will need a dado-wide insert specific to your saw, which can be hard to find, but are pretty easy to make.

No he probado ni otras marcas, ni en otras sierra. Tengo la sierra de mesa venir y me ha funcionado de maravilla. No puedo sacarle todo el rendimiento porque el eje no me permite más de 10 mm, pero me ha gustado como trabaja. Hay que ir más lento que con un corte normal, pero es de esperar ya que tiene que quitar más material. Por lo demás, estoy muy contento con el set, y sé que me va a durar mucho tiempo
