Small stump removal
I actually used one of these to grind down a small tree stump in my yard so I could mow over it. If you attempt to do the same, word of advice is to cut the stump way down as close to the ground as you can and then trim off the remainder with this grinding wheel. It takes a while and I wouldn't try a large stump with this at all, but for a small 10-inch stump it worked well. Took about 45 minutes with a few rests.

This Disc Works GREAT
This Shaping Disc (Course Extreme) works REALLY well. It is very aggressive regarding the amount of material it removes, so a bit of practice is beneficial to dial-in the results. Build quality is excellent, and it appears that it will last quite a while without significant wear. Overall, I am very happy with the purchase.

Works great. Takes a bit to learn how to use
This is a really nice cutter, it does not grab hold of the work piece or throw the grinder around. It took me about 20 minutes before really getting the hang of it and I've used it multiple times on may different projects

Amazingly great product
I rarely write reviews. But this so exceeded my expectations that I had to write: - It's solid - It's extremely well balanced. In fact, so well balanced that it has a bit of a gyroscopic effect that keeps the tool straight. - It's surprisingly quiet especially for what it does. - It creates fine sawdust vs big chunks that I expected. While this is the coarse model, it left a rather smooth finish which was also unexpected. - It even looks cool. My application is that I needed to hog out a 1-1/2" wide and 1/2"deep slot of the inside of an 8-foot column wrap that I built for our porch columns. I had used a variety of tools on another of the columns and it took forever (maybe 45 minutes). With this tool, I completed the job in about 3 minutes. This product and similar do seem a bit expensive but given the time saved, it's hard to argue that this wasn't worth it.

Goodbye 60 grit sandpaper!
I learned about this from watching Blacktail Studios videos on YouTube. I make oak epoxy resin tables. Oak laughs at sandpaper. My belt sander could barely make a dent in it. A planer or a router can hog off material, but for freehand shaping this thing is amazing! Be warned, though...they call this EXTREME for a reason. Even on oak this thing will remove wood with almost NO effort. Sounds great, right? It is...until you mess up your project with 1 slip. This is not for finishing work. This is for rough shaping and hogging off wood quickly. Also...60 bucks seems steep until you realize that this thing doesn't seem to dull and will likely last me forever. My next purchase along these lines will be for a less extreme Kutzall disc.

Removes material quickly.
Great product, a little pricey but worth it. I use this for making wooden bread bowls and it removes material quickly. Alot safer than the chainsaw blade disk.

Fai carving? Allora vai tranquillo.
Il tuo settore di riferimento è il carving? Scolpisce lastre di legno o fai sculture? Allora la serjserie dischi non puoi non averla. Costano davvero tanto, ma non esiste un prodotto di concorrenza che possa essere paragonato. Sicurezza? È il primo parametro che devi tenere a mente. Lascia perdere dischi con lame, denti o altre oscenità. In caso di rimbalzo perderesti minimo le dita. Se fai carving e sculture di vario tipo, questi disco ha un rimbalzo praticamente assente (a patto di essere usato i modo corretto) e mangia davvero tanto tanto materiale rimanendo sempre scarico e pulito. Ho provato anche prodotti con occhi a mandorla fatti copiando questo sistema, niente non possono essere paragonabili, perchè quando sono nuovi mangiano i primi giorni, poi si impastano e non tolgono nulla. Dovrai pulirli con diluente per resina e tanta pazienza e si impasteranno di nuovo... questi li uso da tempo e sono sempre puliti dopo l'uso perchè I denti sono stampati i modo conico e non sono semplici riccioli sollevati come una raspa. 68euro per 1 disco sono tanti? Si certo. Ma non tornerei indietro.

You can't cut a right lot with Pooh!
Clogs up very quickly leaving it useless. The Arbotec alternative is 100 times superior and worth the extra cost. You can't cut a right lot with Pooh.

Amazing
I’ve been using cheaper carving discs before. But the kickbacks resulted in one too many injuries, so I decided to change to premium discs. And it was soo worth it!! Kutzall discs are such a joy to carve with. No kickback at all for me. I love wood carving even more now 😁!

du très bon matos
on le trouve un peu cher, mais en regardant les commentaires et étoiles des produits équivalents mais moins chers, on comprend qu'il y a de l'usure rapide, ce qui n'est pas le cas de ce disque que j'utilise assez souvent depuis plusieurs mois. je conseille de le monter sur un meuleuse d'angle à vitesse variable, de sorte à ajuster le mordant du disque en fonction des circonstances. Je l'utilise pour faire des arrondis sur toutes sorte de bois, ou pour dégrossir des surfaces brutes. Les dents à la périphérie permettent de creuser le bois, en trouvant le bon angle, le disque est très polyvalent. Bref, vous voulez un disque qui arrache du bois, c'est l'outil qu'il vous faut.
