Dremel 4000-2/30 120 V Variable Speed High Performance Rotary Tool Kit

Dremel has always made a quality tool, with the exception of the "chuck that connects the heads, that is why I am replacing. The other lasted years and the motor still works, however the chuck assembly need to be re-engineered so that a tool is not required to tighten and the bit does not spin in the collet

GET THIS DREMEL (with Prime shipping)I damaged my 7 year-old Dremel and had to replace it. Over the course of 7 years, I used my Dremel every week to grind my dogs' nails. One dog has soft nails and the other's nails are dense. I got my puppy 7 years ago and got a second dog 5 years ago. I tried one of the grinders marketed for doing dog nails and those are crap. Over 7 years, I ground down 2 sets of pug toenails every week. I also used my Dremel to remove a section of baseboard for bookshelf installation. So I can't comment on many of the uses for a Dremel.When it was time to replace it, I looked for a version with a separate on/off switch from the speed knob. I also wanted one that was at least 30,000 RPM. That led to the Dremel 4000. I didn't need the case and really only needed one sanding accessory, but that's not an option.DON'T BUY THE UBANTE - While searching for the Dremel 4000, I noticed the cost started at $75, and that there was an UBANTE U300 with variable speed from 10,000 to 37,000 RPM. It had good reviews (4 1/2 stars and quite a few reviews). Since I use it for only one thing (dog nails), I thought it would be fine. It was not. The sanding head was either way too rough or way too smooth, and didn't even fit snugly on any of the shafts. When I ground the dogs' nails, the rotary tool slowed down and jerked when I touched their nails. It couldn't maintain its speed. It also ran very hot. My poor dogs, which are perfectly calm for nail trimmings kept jerking and trying to get away. After 2 uses, the entire casing began vibrating enough to make my hand go numb. I'm throwing this unit away. I'm not even going to insult someone by giving them this. I have no idea how this garbage got a 4-star rating.BUY WITH PRIME SHIPPING - I immediately ordered a Dremel 4000. There were 2 options - with Prime for $75, and Free shipping and one-week delivery for $45 from VMInnovations. I could wait a week to trim my dogs' nails. So I ordered the Dremel 4000 with free shipping. The order information told me that the item would arrive in 4-8 days. The same day that I ordered it, the seller indicated that the item was on its way to the carrier. Yay! I was hopeful that it would arrive in 4 days. On the 4th day, the tracking indicated that the item was on its way to the carrier. There was no change on the 8th day, but the order info told me the item would arrive that day! I didn't have a package when I got home from work and I checked the app. The information had not changed. At 8pm, I checked it again. This time, it told me that my package was late, and that if I didn't receive it by Saturday (day 13) that I should contact Amazon support. At that point, I ordered this Dremel 4000 for $75 with Prime Shipping. It arrived 2 1/2 days later (on day 11) and I still haven't received the VMInnovations order. As soon as I receive it, I'm returning it.ABOUT THIS DREMEL - As soon as I got this Prime order in a timely fashion, I opened it, set it up, and used it. It was a little tricky to figure out how to put on the sanding tip that I wanted. I understood how to put the metal tip in the shaft. I've used a drill before - You hold down the button and unscrew the metal piece to open the inside of the tip. Then you put the metal "bit" or whatever inside it, hold down the button and tighten the piece back. The wrench helped. What took me a few minutes was figuring out how to swap the rough grit sanding circle with the medium grit one. Basically, use the handle of the provided wrench as a screwdriver in the end of the sanding tip. There's a little screw there. When you loosen the screw, the sanding hoop piece gets loose. Swap them and tighten it. I then used it for my dogs' nails and was super-duper happy. It worked wonderfully. The nails were done quickly and with no nervous dogs. The Dremel ran smoothly and the air that blew the nail dust seemed better on this one. I also like the separate power/speed controls. It allows me to leave it on the same speed every time.USING THIS FOR DOG NAILS - I use a variable speed setting of 22 and the medium sanding tip. This works for both of my dogs: one with dense nails that grow slowly and the other has softer nalis that grow quickly. I sit on the sofa with my feet on a stool, and lay each dog (Pug) on their back with their head away from me. They've been doing it for years, and are perfectly calm. Plus I always give them a treat afterwards. If you're new to trimming dog nails, make sure you check YouTube or something to learn how to do it. Dremels are great because they don't leave the sharp edges like clippers, and if you do accidentally cut the nails too short, they don't bleed as long.

Good ratings, good power, all I need to do crafts and small things in construction. Pretty good weight, adding the extension will take me a little while to get used to.

Several attachments

I bought this as a gift for my wife, she absolutely loves this machine and all of the attachments. She like to redo old furniture and this helps her out with the reconstruction of patterns that are existing when she has to replace parts of the wooden furniture. My wife likes the weight and functionality of the tool. It's nice everything stores 🏪 n the tough case it came in.

So why is this one better than the other Dremel kit options out there? It might not be but I was looking to not spend a fortune while getting what I needed and this delivered! I needed it to be organized and easy to put away into a small closet. The case this comes in is unbelievably organized and I really truly appreciate that. My one complaint about it is that it's so organized up until just a tiny compartment box for most of the accessories. There's a place for all the big accessories within the case, and they're labeled with pictures etched into the plastic. But then you go to get the right cutter head and you have to open up a tiny box full of accessories and no real organization. At this price point I'd expect a little bit better for the storage of pricey parts. But I was happy and surprised with the organization of the case itself.It came with all the accessories I needed and since it came with the keyless chuck I'm able to use some of the smaller drill bits I already owned. But since it's corded and the cord isn't very long I do prefer my cordless screwdriver for hanging pictures and shelves.When you're indoor storage options are limited this really makes a great tool to have since it can do such a wide variety of jobs. I used it to cut nice circular openings into a self made hidden litter box bench for my cats, and to cut an opening into the litter box I made from a plastic bin since no litter boxes would fit as perfectly in that bench. I used it to sand down my doors that weren't closing, to drill holes for putting up my towel bars in the bathroom - all within the first few days of owning it so I know I'll be getting lots and lots of use out of this.
