    I use this item for wood shaping and find its is not any better than the Ace Hardware version which is $1.50 less. So if you are trying to save a buck then reconsider your options. They both wear out within a half an hour of steady use. I would think it would be the same on metal for rust and paint removal.

    Ive used several of these (60 grit and others) for grinding welds, deburring, chamfering and similar tasks. These are pretty good - they cut quickly, leave a decent finish, and last a while. That being said, I prefer the Walter 15W456 - they cut a bit more quickly and you can trim them when theyre used up to get a bit more life out of them.

    Nothing against Dewalt this is a quality product. On this order two DW8310 discs were sold / shipped by Amazon store. One disc was obviously used and with most of the sanding grit worn off. It was just thrown in the box with no packaging. Sending out used products or someone else’s return is completely unacceptable. However, receiving used or old (discontinued) products is an all too common theme here. In addition, most of the discs sold here do not have the required expiration date stamped on the wheel because they’re not manufactured in the US. Using a grinding wheel is the most dangerous tool. Grinding discs can break apart as the bonding material deteriorates with age which is why they stamp an expiration date. There are enough risks when using cut-off wheels and grinding wheels. I’m not looking to increase those risks in so I won’t use expired abrasive discs. I replaced these by ordering directly from manufacturer and paid the additional shipping. I’ll be doing this with everything but cat litter and other non essential consumables. It’s worth spending a few dollars more to get new.

    Bought this to sharpen my mower blades, based on a YouTube video I saw. These work so much better than a grinding wheel. Fast and easy sharpening, wish I had bought these years ago.

    This thing is awesome. I have a few uneven pieces of wood flooring that Id been burning quite a bit of time slowly sanding down. I decided to try this out instead and in about 10 minutes Id managed to do what would have taken a few hours with the sander. That being said, be very careful since it removes a lot of material very quickly.

    Works great for sharpening lawn mower blades, without being too aggressive…
