Dremel Lite 7760 N/10 4V Li-Ion Cordless Rotary Tool, Variable Speed Multi-Purpose Kit, USB Charging, Easy Accessory Changes - Perfect For Light-Duty DIY & Crafting, Sanding, Engraving and Polishing

Works VERY well!I use this for my 70 pound dog, his nails have always been a hassle to trim due to his size and his nails are all black. Using a trimmer that cuts the nail off is very hard and usually too much is takin off leading to him bleeding.Getting this nail grinder has helped SO much, not only is it extremely fast but now we have no more accidents with too much nail coming off.It’s very heavy duty and has some nice weight to itI don’t think this grinder will be breaking ANY time soon, so for what I payed it was definitely worth it for the qualityThere’s a few different vibration levels as well, for my 70lb dog and his rock hard nails I only ever use the 2nd levelIt’s fast and gets the job doneI could easily see level one being used for smaller dogs!I also love all the bits the come with the grinder! Granted I probably won’t ever use them but I think it’s a cool addition for hose looking to use the grinder for other things!Definitely get your values worth for money

I've had the Dremel Lite 7760 for some time now and conclude it is an excellent unit if used for it's intended purpose:Dremel advertise the 7760 as an entry level tool. I also have a mains powered Dremel 4300, which is the current top model from a versatility and power perspective. The 7760 will perform just as well as the 4300 for light jobs such as engraving, sanding, brushing or light grinding. But it doesn't have the power, duty cycle nor high speed of the 4300. They are intended for different applications. But the 7760 does some things the 4300 either cannot do, or it becomes awkward/time consuming to use.The 4300 or any mains power tool requires a cord and plugging into a wall socket or extension cord. The 7760 is lighter, shorter and can get into places that may be impossible for the 4300 or other long tool. Because the 7760 is battery operated, you can use it in the car, caravan, boat, attic or garden etc.; anywhere there is no mains power.The 7760 fits the hand much better than the 4300, when holding the tool like a pencil. It is shorter and lighter than the 4300, enabling holding the tool close to the cutting bit and enables greater control. While the 4300 can be gripped like a pencil, my hand becomes tired after 10min or so; while using the 7760 like a pencil is much easier to use and less fatiguing. The 7760 is battery powered and therefore cannot be operated as long as mains powered units--when the battery loses it charge the tool stops: Time to recharge.I did a couple of no load operating times for the 7760. By no load is meant the tool was turned on (just allowed to run free) and run until the batteries became flat of charge, and I timed the duration. Setting the switch on the lowest speed, it ran for 55mins. Recharge the batteries, set the switch to highest speed, and it ran for 30mins. Of-course, placing a load when using a tool entails shorter operating time, and the greater the load the shorter the running duration. So how long the tool will run varies directly with how hard you require it to work. If the tool is asked to work and it is being strained, a safety feature is engaged and the tool stops. Now turn the switch to off and then back on and it will run again. I tried pushing the friendship of the tool, and indeed it stopped. If you require a more powerful and longer running battery tool, perhaps you should look at Dremel's 8220. The 8220 is longer and much heavier than the 7760.I am doing electronic work as well as jobs around the house. If the job is light, such as wire brushing a rusty small tool, the 7760 will be quite adequate. It will be quite the thing for sharpening garden secateurs or sanding a small piece of wood prior to painting, engraving names on some tools, grind figures on a ceramic pot: All these and more are well within the capacity of the 7760.The battery is recharged using a USB connection which will supply 5volts at 1amp. Recharging time is 2hr 40mins. I tried using a bigger battery charger, and it still takes the 2hr 40mins, so there is no provision for fast charging.Many of the things I do are short in duration, and not requiring high power and the 7760 will be quite satisfactory.I showed the 7760 to a man who makes his living working on electronic equipment. Immediately, he saw its utility and I've ordered one for him.

Love it. I use it as a bead reamer. For those who don't know.....to make the holes in beads bigger. Love the fact it's cordless. And that I am able to use it with one hand. I mean it's Dremel it's good quality in my book. I do have to charge it atleast once a week but that's because I feel like it's not working at its best. Plus I can be inpatient too. Otherwise it's a good tool to have even if it is to make jewelry.

Seven months in with this Dremel model and sharing my experience is in order. I ordered this because my similar tool (different brand) would not work with my DiamaGroove tip and the 8050, previously recommended by so many dog people, was discontinued well beforehand.Pros:1) It works with the DiamaGroove tip, no alterations needed!2) It is relatively lightweight, which I appreciate.3) Adequate RPMs for efficient nail maintenance.4) The battery life is pretty decent. I can usually go several sessions for my two dogs between charging. I tend to leave it on while inspecting the nails and positioning the dogs, so it definitely gets run during each session.Cons1) LOUD; this is not a model I would consider to be quiet, which is a consideration if it increases your dog's anxiety or you want to avoid disturbing the household.2) The charging is a touch counterintuitive, if you (or me, in this case) didn't read the instructions regarding this beforehand: a green light means it isn't fully charged.3) This model gets warmer than my not-Dremel hand tool and an older Dremel tool I used to use. I'm glad the tip I use for their nails offsets that, but it does feel uncomfortable the way I sometimes hold the tool. As an aside, if you want something other than the sanding barrel tips, seriously consider saving for the brand name diamond tip: I am so glad I finally did.

This Dremel has outperformed my expectations. I'll be honest, I specifically bought because I have very weird toe nails and after seeing the pedicure people use rotary files, I thought this would work. And, it works much better than the sissy ones they have at the pedicure salon. I have also used it for various other DYI projects and it just continues to perform very well. I only use it for small projects, when I need to polish or engrave smaller thingsin a hurry and so it is much more convenient than my plug-in Dremel which I still use for larger projects. The battery life is also longer than I expected.
