Works well, makes short work for your carvingsOnly used the grinder so far. Took 5 minutes for it to get completely dull while trying to remove thinset from the floor.Locking placement washers dont fit 5/8 shank grinder stem. Bits do fit 5/8 grinder shank.good priceToday received my order and u was ecstatic. I got the Woodcarving Disc&Chain Saw Blades and Coarse Disc. The only problem, the bolts that came with it, do. It fit my grinder. I have a bauer grinder that I bought from Harbor Freight. The enactment fit but built that comes with the attachments are smaller so I cannot use them.. and my bolt does not fit over the attachments.The attachment themselves are very nice.The washer and threaded lock washer were missing! This renders the carving disc unusable as the diameter of the grinders washers are larger.I used this to grind a few tree stumps in my garden into planters. It works as advertised and cuts like a champ. This could be a dangerous tool if not used with great caution. I would recommend it, but please be safe. I was not able to use the accessory grinding wheel that came with it on my 30 yr old Craftsman angle grinder.I am assuming the “Coarse Disc” needs to be used on a “Special” grinder, not the same grinder that the Chain Saw blade fits? I have no idea how to make this fit on the same grinder safely without some unknown adaptors. Their pictures look like it is used on a normal angle grinder.
