Certainly super sharp and work great. Able to pinpoint my width with ease. Cuts great and super effective. Great price compared to other options. Very happy with this purchcaseGreat blades for the money but the shims I found to be hard to use. I bought some oversized magnetic ones that do the trick.Easy to use does a awesome job of cuttingI use these on a Shopsmith.I have a 6" dado set from Oshlun that work really well also, but could not get the depth I wanted when using a crosscut sled. The sled was key in gaining the accuracy needed for the box joints I wanted.This set solved my depth issue and made the job go smoothly.I wouldn't hesitate to recommend.I have made plenty of rabbets with this blade stack, as well as the 8" version. I would just use a bit more than 3/4" of the stack along with a zero clearance fence to make easy rabbets.Recently, I started making dados, where I need to dial in a precise stack thickness, and started using shims. I had an accident in my shop that I ASSUMED was something I was doing wrong. In essence, with a 3/4" stack, there isn't quite enough room for the arbor washer, so only the arbor nut is used. After a series of cuts, I turned off my table saw, and the blades continued rotating freely. To my horror, they began to drift into the throat plate, (down the arbor) chewing it up. I heard a CACHUNK, and hid behind a table to be cautious, until I could hear that the blades had come to rest (more than two minutes! these things have a ton of inertia!). Though the blade was totally performant while making the cut, after turning it off, the arbor nut had completely come off the arbor, and struck some of the blade teeth on the way down.After searching for the nut (and also finding two carbide blade teeth), I decided that was enough for the weekend.walking through the events in my head, I concluded that either I failed to tighten the arbor nut beyond finger tight, or the keyed arbor washer is 100% required for safe operation, and the experts who have been doing this for four decades without incident were just lucky, and I wasn't. After discussing with some of my peers, we were in agreement that if I'd truly used the tools properly, that shouldn't have happened.This weekend, I picked up ANOTHER one of these dado stacks (the 6" version), as they're reviewed very well and are cost effective. I set up a series of experiments, building up to a thicker dado stack, taking great care to appropriately torque the arbor nut, and turning the saw on and off, making short test cuts from an extra safe position then turning the saw off just to get a feel for it.When i set up cuts with the shims, I really played around with the right way to order it, how to get it on the arbor without jamming on the threads, and get the nut tight. These shims seem to have basically zero clearance bores, that fit extremely tightly on the arbor, so they take some handling to get into place. Regardless, even when using the arbor washer to shield the nut from reverse torque associated with the decelerating stack, the blades are able to eventually loosen enough to splin freely around the arbor, IF A SHIM IS IN USE.After repeated tests, I have found that when I do not use a shim, the cuts can be made safely (with or without an arbor washer). If I do use the shim, I am NOT consistently able to be sure it is properly seated and make safe cuts. These things turned the use of a dado blade from a normal shop activity to a nerve wracking game of roulette with death.I've picked up some magnetic shims with oversize inner diameters that stick firmly to the sides of the blade, and now I can make precise width cuts without worry. I DO NOT RECOMMEND USING THE SHIMS THAT COME WITH THIS SET.NOTE: It is possible there is a compound failure, that my arbor nut is defective in some way, or that my arbor is a few micrometers above or below 5/8", and combine with the sub-optimal conditions of using a shim, the issue is exacerbated. I've ordered a replacement washer and nut from the manufacturer and will test again with those.Dado set cuts a clean, square bottom. The set arrived wicked sharp and of a consistent diameter.The blade design nests adjoining blades which produces a clean cut across the width.The set arrives in a sturdy cardboard box with a foam insert that keeps the carbide tips separated during storage. A metal box would be a worthwhile upgrade as this set will last a lifetime.The shims are the only area where I have a problem. There is absolutely no slack in the internal shaft diameter. They are an absolute bear to get on and off the arbor of my Jet table saw. I find that I need to use a chipper blade to push/pull the shim on/off the arbor.Other than the shim hole diameter being a touch too tight, this is a great value.This is the third dado set I've bought over the years. The Freud that I'd used for well over five years needed replacing.I bought the Oshlun after thinking about it for a while. I liked the Oshlun full-blade inner cutters. My previous versions had vane cutters on the inside with two carbide chipper points separated by 180°. Aligning the Freud stack required an inner chipper arrangement from experience to preclude nick-cuts and occasionally reshuffling the inside blade saw spindle balance. No knock on Freud ... the dado was worked hard and lasted a long time.My first project for this Oshlun was on 14 4x6" half-lap joints. The Oshlun dado is noticeably heavier - more blade, more carbide tips. Noticeably tighter tolerances on the saws 5/8ths shaft. The tighter tolerancing extends to flatness. The blades arrive lightly oiled and oddly joined with a tight vacuum weld between the uber-flat blades.The dado cut at max thickness was like a hot knife through warm butter.Much better than expected. It's the best dado set I've owned.Needed to replace old adjustable dado blade. This is a very well made set and provides with shims a very accurate build width creating a very smooth dado cut on sides and bottom. Time will tell, but so far this has worked very well. My only complaint is the shims ( well marked, and multiple thicknesses) seem to have a slightly smaller arbor hole. This makes them a little harder to remove from the arbor than they should be.Cut 1 was made with a Mibro Buzz 8" at 59.23$Cut 2 was made with a Freud 8" at 129.96$Cut 3 was made with a ToolWay 8" at 45.98$Cut 4 was made with a Oshlun 6" at 88.31$The Buzz blades made the wost cut of all shape like a W, for sure this blades was never tested by manufacture. The Freud and ToolWay were about the same with a small slope from left to right witch could be acceptable to work with but not to my level. The Oshlun blades made me a PERFECT box, very satisfiedI have a US made table saw imported several years ago. It has a 5/8th arbor that is 38mm long and a separate saw plate to accommodate the wider blade. It also has enough horsepower to drive the considerable weight that the full set of these will add to your motor. Don't even think about buying this set if you haven't got something similar. And don't consider fitting them onto a chop saw!The full stack is very heavy and if not comfortably secured could wreak havoc in your workshop. As it is the performance is fantastic. Effortless and crisp clean rabbets and dadoes performed in seconds. The blades are uber sharp and the shims supplied mean you can achieve cuts in tiny increments up to just shy of an inch per pass. Being a US product it is sized in Imperial but you can easily convert to metric (I use a micrometer and just hit the convert button). You need to remove a conventional blade guard assembly but you can retain a riving knife if yours doesn't sit higher than the blade although it serves no purpose here being a fraction of the width of the cut. I don't buy into the idea that these are dangerous - any number of tools in the wrong hands can kill you. Just make sure you are fitting them to the right machine. Highly recommended.The 6in set allows my Bosch saw nearly a 1 inch wide by 1 inch deep groove. All I'll ever need. Lovely sharp 90deg corners. Just now I'm setting up a jig with sizes and settings. Hard to imagine how a dado stack could improve on the Oshlun? Bosch have been a bit miserly with my saw arbor length, although there is room for a little more length, might prove restrictive in time. However, that's not Oshlun's fault! If the ultimate width size (the whole stack) is important to you, beware! Lastly, zero detectable vibration. If you need to hog out a very wide deep groove this is the stack for you. It motors!I have yet to use this 8" Box and Finger Joint Set, but I know from just looking at the way they have been engineered, they will perform perfectly.Bought this as I've got to make 20 drawers with finger joints out of 6 mm birch ply. just using the two blades without the chippers all the cuts are clean and accurate. Very happy all round.
