User questions & answers

Question:	Does anyone use these in a die grinder? 3450 seems like pretty low rpm rating for it
Answer:	it varies from 0 to 6800rpm in less than a second. ;Dvariable speed would have been a feature i would appreciated a lot and would have made this tool even more useful. but still i'm using it a lot.
Question:	I want to sharpen lopper blades, will this sharpen fairly hard steel
Answer:	I find it to be far more ergonomic. Very smooth and responsive. You’ll love this grinder! Just be sure to get at least a 5ah battery or more for. 2ah only last like 10 min of continued use.
Question:	Need to cut carpet tack nails flush with the concrete because they can't be removed. Will this work pretty easily
Answer:	I've used this grinder to cut 1/2 in Hardiebacker when doing bathroom remodels. I use a cutoff/wafer wheel which isn't ideal for this use but it works. In my opinion it had adequate power but the fully charged battery lasted roughly 20 mins of almost continuous use (I cut about 4 sheets for a tub surround). So, to answer your question, I know it will cut concrete with a diamond wheel, but if I needed to use it continuously for an extended period of time I'd go with something corded which is the case with most battery powered saws/grinders. I hope this helps.
Question:	Can i use it on my cast iron pans
Answer:	Any DeWalt or compatible 20v Li-Ion battery will work. They range from less than 2 Ah all the way up to 6 Ah. They'll all work the same, but the smaller the battery Ah capacity the less time they'll power the tool before recharging.I urge people to consider buying only the bare tool and buying generic DeWalt-compatible batteries. The difference today between the bare tool and the bundle that includes two 5.0 Ah batteries is $150. For $75 or less you can buy two generic DeWalt-compatible (IMPORTANT! all brands are keyed differently and are NOT interchangeable) 5.0 Ah batteries that work just fine. I have purchased 14 DeWalt or compatible 20v Li-Ion batteries thus far. All are working fine, and only two are DeWalt brand. The rest are Enegitech and some other no-name brands. I received one generic that had a problem, and the problem was trivial: the three "fuel gauge" lights would intermittently stay on permanently after the test button was pushed. The vendor immediately offered to refund half my money (I purchased them as a pair), or replace the battery. We decided to take the money and see how much of a problem it was for the lights to stay on. Wouldn't you know it. The problem soon went away! Sticky switch, I guess. But that's the only issue I've had, and we've used these A LOT. For $150, you can either buy these two DeWalt brand batteries or *4* generics. Trust me, if my experience is any indication, you'll be way happier to either spend half as much money for the same thing, or the same amount for twice as many batteries. Note: a 5.0 Ah battery lasts a LONG time. I don't have a grinder, so I don't know how long it'll run, but I have five brushless impact drivers, a hammer drill, a circular saw, a "Sawsall", and a portable shop vac, all DeWalt brand 20v Li-Ion tools. They all run GREAT on the generics. DeWalt doesn't manufacture batteries. They no doubt buy their batteries from the same Chinese factories that produce the generics. The only thing that's different is the cases and the way the slots are keyed so you can't use Black and Decker, Milwaukee, Bosch, etc. batteries interchangeably. The actual Li-Ion cells inside are all the same.

User questions & answers

Question:	where made
Answer:	Who cares. This was cost effective and works great. Alternatives were all plastic. This is metal and will last...
Question:	Do they fit a dremel
Answer:	I recommend that you purchase GVODE 2-in-1 attachment kit, a meat grinder attachment and a shredder attachment. The grinder is metal, and the shredder is plastic, the price is 89. However, I believe that the price of Black Five and Cyber Monday will be lower.I think this price is very good value, because they are not famous brands, so the premium is not much. I have bought it for more than half a year and use it 3-4 times a month. Follow the instructions for cleaning and maintenance, it is still in good condition. I found its link from amazon, hoping to help you. https://www.amazon.com/gp/product/B07QKH1DB1
Question:	Can i use these to cut/sculpt hard wood
Answer:	That person is no smarter than the meat grinder. It's aluminum.
Question:	Will there fit into a cordless dremel tool
Answer:	The disc itself is 7/8" arbor. I think you meant to write 'Porter Cable', either way I don't think a drill has enough rpm's and you won't have the protection of a grinder shield. You don't want to get hurt, keep it safe and good luck.

User questions & answers

Question:	What rpm
Answer:	They're quarter inch shank they'd fit inside the Collett but why would you use them on a router ?
Question:	Can these be used with a router
Answer:	It should The bigger die grinder can take both 1/4 shanks and 1/2 shank bits.there is a collet adaptor that usually comes with the grinders For the different size
Question:	Would this work with a 1-1/2" Die Grinder
Answer:	no, i dont think so, these are 1/4 inch Shank, dremel is smaller. die grinder is best, air or electric. Dremel is for little stuff
Question:	will this work in a dremel
Answer:	Use a 1/4 inch drill bit to drill a pilot hole then use this to enlarge hole to the desired diameter. That will prolong the life of this bit. This is more for thin metals 1/8" - 1/16" thickness. If your drilling a lot of holes in metal and you know the size diameter you need you should look into a carbide hole saw and some cutting oil like tap magic. It would depend on the thickness of the smokers aswell. Hope that helps. If you don't know the size hole you want this is good because you can keep making the hole a little bit bigger one step at time hence the name "step bit" good luck !!!
