My drill only spins at 550 RPM. Would this be sufficient for the sanding process? (I know instructions say 1200 RPM)

When I did mine I didn't know there was a certain RPM, guess I should read all the instructions. I used my cordless drill on low setting (475rpm) and my lenses turned out like new.

It's possible, but definitely not recommended. I would really discourage you from trying it, if you are not using an AC (electric) drill. A drill powered by a battery pack would not be able to sustain the 550 rpm for any length of time. Ultimately I would suggest borrowing or purchasing a drill that meets the requirements. On Amazon I found a Black & Decker (DR260B) for under $20.00 with peak power at 1500 rpm's. If you think you will ever use the drill for other things, I would suggest looking for a better drill. You can spend $50 - $60 on Amazon and get a really nice drill for the average home owner. I am not a professional nor do I claim to be an expert; however I am a hobbyist and am not new to tools. That being said, these are a few brands "I" have had good luck with in the past: DeWalt, Bosch, Makita, Milwaukee, Hitachi, Jet... There are many others but the few that I have listed here make models that are available in the price range I quoted above. I'm sorry if I have provided more than you needed, I just wanted to make sure you knew you had affordable options. Thanks for your patience and good luck

I'm not sure. I know that you have to use a drill for quite a while to complete the whole process, so I used a corded (not cordless) electric drill. If I were you, I'd find a drill that can get to the needed 1200 RPM. And realize that corded drills are sometimes cheaper than cordless drills.

Most small grinders spin to fast. Rpms should be at 3000 or less so you probably need a varible speed one. And they work much better with water. Without water they get too hot. I used mine with a random orbit sander since I did not have a polisher that can use water.

As others have said, it is not "drill friendly" and would have to be adapted. That being said, a drill does not spin at the high RPM needed for maximum benefit from this pad.

There is a switch on top of the drill, low and high. The low is 0-350 rpm, the high is 0-1500 rpm. There will be more torque on low switch, less torque on high speed. If you are siphoning water with a small hose, high speed will work good (half inch hose). The bigger the hose, high speed will not work. Remember, 1 gallon of water weights right at 8 lbs. Hope this info helps you.

Yes it works exactly like an orbital buffer/sander/polisher. I love mine and I have not had any problems with it. I use it on my motor cycles and it's the perfect size. I would consider a different option if it was a larger vehicle (SUV, Truck). It's important to keep in mind the drill RPM requirements... not less than 1200 and not greater than 3500. Most cordless drills do not fall in that range, so you will want a corded drill. The other thing to remember is that its speed that polishes, not pressure. Do not expect great results if you are pressing down hard with it.

I have a 3 dremel tools each with their own min/max rpm and I always set it for maximum speed - rpm doesn't matter - what does matter is keeping the glass and drill tip under water and let the tip do the work. If the fused glass is not compatible, you will soon realize through shatter marks. I hope this helps.

My DWD520 is variable speed in hammer and regular drilling modes. I hope this helps, as I think it may be a error in the listing. Mine works just great as well. Keith

You Can use the in whatever you have that has a small enough chuck. However the key to using tiny bits successfully is the R.P.M. YOU NEED VERY HIGH R.P.M. for these small bits. That is why the Dremel is a good tool for them. I don't think you can get the speed you need from a hand drill.

I recommend a low RPM motor that has a 5/8 shaft with keyway. You can get 5/8 bore pulleys at a hardware store. You may have to order the pulley that goes on your mill since I could not find that size at the store. My system is configured with a 5" pulley on the motor and a 3" pulley at the mill with a 30" belt to get an RPM from 83 to 133. Your motor doesn't necessarily have to be that low of RPM but you do want to crush your mill any higher than 200RPM. I spoke to Todd Millar, the inventor of this product and he recommends no more than 200. Wether you have to reduce or increase your speed, go to this site to figure out what pulley size you need to achieve your desired RPM: blocklayer.com/pulley-belteng.aspx

I can only speak for the DD750X that I have and it can grind 118 and 140 angle drills with the latter being better for tougher materials like stainless. The 750 is the only model that goes to 140, the 500 goes only to 135 so the 750 is the better choice if drilling tough materials is important to you. Clearance (relief) angle is the other important variable in grinding a drill point. The 750 does have adjustability but I don't recall exactly what the limits are right now, but it is adjustable. The best thing to do is go to the Drill Doctor website and look at the user manual and the drill angle guides they have there. Even if the DD can't get the exact geometry you're after it will give you a good symmetrical starting point for a final touch-up on a grinding wheel. Hope that helps.

Hi mark. Without knowing " how fast is enough" for what you are doing, I would hazard a guess that there is a problem with your grinder. They should have a max rotation of about 10,000 rpm max.

In a word.....No. The output of this drill is rotary motion.....like a regular drill except it has a high speed "pounding/hammering" component too. It is for use with carbide-tipped drills ... and it drills round holes in concrete quickly. That is ALL is is good for. Sorry.

Dremel does not indicate this tool is ideal for drilling. Its two-speed setting allow you to use the low-speed setting for cleaning applications and using brush accessories, then switch over to the high speed setting for routing, cutting and sanding applications.

i used it on a hand grinder. it worked at full speed but at lower speeds it looses a lot of torque.

Simplest answer is your drill probably runs at too low RPM, try a faster drill befroe changing bits.

Everything you buy is yours. If you need the hole bigger, cut it bigger. I have a Jet® mill drill. The fastest it turns is 2500 rpm. Occasionally, I need to use tiny drills on aluminum. 2500 isn't enough. I have a Makita® 1/4" drill. VERY high RPM. I am considering one of these to use it as a drill press for tiny holes. The biggest challenge is to mount the drill so the bit is perfectly perpendicular to the table. More kludging. BUT, when finished, it will be a very much needed and used tool.

If you get the little bits with the hex base. Only in softer materials like wood or plastic. The rpm is slow for a drill.. So for just a few instead of getting out the drill it may work.
