This things awesome.
I know people say this is unsafe. Lol. I guess their trying to take off inches in a few seconds. But this thing works great.

Great, however
The grinder works as intended, it chew's up wood pretty impressively. But hold on for your life. The only reason I didn't give it four stars is because if you're using it on an x-lock adapter on a Makita or bosh angle grinder and you use it for more than 20 minutes straight you will not be getting the wheel off the adapter. The two fuse into one basically.

Great budget option!
This removes wood as well as the higher priced options. It is a course cut but great for heavier removal. I do custom trim work and am using it to cope my inside miters. This is 10x better than traditional flap disks and much more affordable than the name brand carving disks, while still delivering similar performance.

Aggressive Cutters, Even for Hardwoods
I’ve been using the more-convex 4.5” discs for the past few months to shape bowls. I’ve tried several other brands of wood-carving discs for the angle grinder, including cheaper imports from Asia, and the OBA discs are the best I’ve found. They’re mild steel, so they don’t stay sharp for very long (when carving a large hardwood bowl, such as 20” diameter and 12” deep, I will often go through two or three discs in the process). But when sharp, they are super aggressive cutters, and, in my experience, well-behaved in terms of kick-back, binding, or pulling in unwanted directions. I’ve used them for local Hawaiian hardwoods (mango, lychee, Milo, Koa), and while they do dull more quickly, they still cut these hardwoods quite well. They do have their limits though, and local Kiawe wood (Janka hardness of 3500 or more) causes excessive chattering and rapid dulling). While using the discs I frequently (every few minutes) blow them off with a high-pressure air gun attached to my air compressor and this helps keep them cutting well for longer. Once the teeth become clogged with wood fiber and resins I soak them in drain de-clogger overnight and then brush out the teeth with a brass-bristle brush. The cleaned-off discs don’t cut hardwoods as well as new, but are still good for less demanding woods and for de-barking. I have found that, when cutting hardwoods, it’s helpful to keep the angle of attack and the degree of pressure somewhat lower in order to avoid chattering, which seems to result in bent teeth that quickly shorted the lifespan of the discs. My only complaint is that I wish the discs were available with carbide teeth. Changing the discs every hour or so of carving does become a nuisance, but a manageable one.

Removes wood!
I bought two of these to grind down a stump with an angle grinder and it worked well over all. It these did the job well, taking down about 3 inches of wood on a foot and a half wide stump, bringing it below the surrounding grass. A couple of things to note. if it gets into dirt at all, it will eat up the teeth pretty quick (I knew I would do something dumb, which is why I bought two). Use a brass wire brush to clean out the teeth every now and then since these remove a good bit of wood and do get loaded up a bit over time. The big thing... DO NOT get greedy and DO NOT turn your angle grinder to the right and use the edge of the tool. Trying to take too much or using that edge will cause the disk to grab and WILL rip the grinder out of your hand, especially if it is a high torque electric grinder. No side handle or gorilla grip is going to keep the grinder in your hands. Its not a fault of the tool, and is 100% on the user to use their head and take their time. Be safe and happy grinding!

Tree Stumps
Used to grind down 3 tree stumps that protruded a few cm above ground level. Worked really well on very hard wood that a 35mm wood drill bit struggled with for multiple vertical holes

Efficacité redoutable !
Efficace mais à ne pas mettre entre toutes les mains. Personnellement je ne les utilise que sur une meuleuse à batterie performante mais ergonomique. En effet j'ai commencé par tester sur une meuleuse filaire trop puissante avec une faible ergonomie et je n'étais pas du tout rassuré par peur de perte de contrôle liée au fort pouvoir abrasif de ces disques. Maintenant c'est redevenu du plaisir quand il faut meuler le bois rapidement et sans trop d'effort. Pour le travail plus fin j'utilise le disque Kutzall.

Eats wood
This is my only experience with these kind of sculpting discs, so I have nothing to compare them with. For me they work excellently and saves me a lot of time. You can let them eat away wood, or use them precise and gently. I recommend using a side gripped angle grinder so that you have two hands controlling it. They are powerful disks that require the strength from two hands to be used effective, precise and safe.

Perfect
Really good carving capability. Smooth and fast.

Impresionante
Lo probé con madera de nogal seca. Se la come como si fuese mantequilla. La sensación de uso es como cuando cortas con una motosierra bien afilada, es decir, ella sóla se mete más y más en la madera, como si hubiese una especie de magnetismo. Va muy bien.
