What customers say about "Key Specs"
Dremel 300-1/24 Variable-Speed Rotary Tool
  • The variable speed works well and cuts well, I am still on the first cutting wheel.
  • I love this little Dremel. Adjustable speeds and easy chuck to lock and unlock.
  • The variable speed is especially important because different materials require different speeds to work properly.
  • Not good for drilling thick steel as the speed is too high (I melted a bit trying to drill the steel shaft of a fan).
  • The on/off/speed select slider is terribly made. I read the reviews, but didn't know it would be this bad. It is very difficult to select the lowest speed, it often slips right back off.
  • I gave 4 stars because it can be difficult to change attachments. I'm hoping to get the EZ-lock accessory soon to see if that reduces the problem.
Dremel 400-1/55 Series XPR Rotary Tool Kit
  • I've owned this tool and the accessories for at least 15 years, and it has never failed me yet. It's a very high quality rotary tool.
  • I Just wish they would make foot pedal that you can adjust the speed with, would make a lot of the work I like to do much easier.
  • I have used the dremel and the cable extension along with some of the bits. The variable speed tool works very well.
  • It gets into small spaces and with the variable speed you have complete control while working on your project.
  • The only problem I have with the dremel is that it gets quite hot when running at high speed.

What customers say about "Size & Weight"
Dremel 300-1/24 Variable-Speed Rotary Tool
  • The 300 series fits in your hand better than the 4000 or the XPR versions I have played with.
  • My son-in-law loves this! It is simple to use, comes in a carrying case and is light weight.
  • I love the 300 S for it's light weight. My hand and arm do not tire after hours of work.
  • It is light, versatile, with just the right speeds for what I need.
Dremel 400-1/55 Series XPR Rotary Tool Kit
  • This thing is so versatile and handy! I bought it initially to do some lapidary work but have found so many uses for it!
  • The Dremel is actually MORE expensive than its alternatives because you are essentially paying for its small size.
  • The versality and small size have made it indispensable.
  • All I can say is this is a great tool. I was always looking for that small tool that would do just about everything.
  • For all my small hobby cutting/grinding tool needs it works ok.

What customers say about "Features"
Dremel 300-1/24 Variable-Speed Rotary Tool
  • The circle cutter is fantastic for creating circles in tile (which is why I bought one, after borrowing a friends XPR).
  • A very good and powerful tool with lots of accessories. We are able to do most of the type of jobs that dremel tools do.
  • There are many attachaments and accessories for every job. I prefer the routing accessories but I use it even for cutting and sanding. It is a small tool for great result.
  • The Dremel 300 and its accessories allow me to undertake a wide range of jobs. For example, I used my Dremel 300 to repair some tiles around my bathtub. Also, the large assortment of accessories provides creative solutions to many handy man problems.
  • I have owned two Dremel tools (a 300 and a 4000); the 4000 lasted less than a year of light use and the 300 lasted for exactly 7 uses. None of them were long or hard jobs.
  • I've gone through several dremels and the 300 was by far the worst. It has two speed settings; slow as hell and fast as sh*t. It makes no sense to have only two wildly different speed settings on a precision multi-tool.
Dremel 400-1/55 Series XPR Rotary Tool Kit
  • Has almost every feature you want. Part on power cord keeps falling off but not a big deal.
  • This kit features the new 400 Series XPR rotary tool, a saw attachment for cutting in tight places, a planer perfect for unsticking doors affected by humidity, a flex light attachment to light up the work area and sharpeners for lawn mowers and garden tools.
  • It is well-made, it does have a lot of cool attachments that in theory work great
  • Also, the Dremel 4000 with all the attachments from my old 400 is unstoppable. It's clearly more of a work tool than the 400 was. The 400 seemed a bit more like a toy.
  • I've already used it to cut through wood & drywall to install outlets in my basement and used another attachement to easily saw through metal.

What customers say about "Power"
Dremel 300-1/24 Variable-Speed Rotary Tool
  • It has plenty of power for what I am using it for.
  • It offers lots of power and fits the bill as that 3rd hand one often needs when tackling life's many jobs, both small & big. A real time saver and a well made, powerful little extra tool.
  • With just the right rpm it delivers enough power for small jobs. I am very impressed with the action of this tool.
  • It has lots of power when you need it and is still great for delicate jobs.
  • The Dremel 300 has plenty of power for the tough jobs but, most of all, it is very easy to manipulate.
Dremel 400-1/55 Series XPR Rotary Tool Kit
  • Great rotary tool - with power to spare.
  • This new unit has more power than previous Dremel's I've owned, enough to even cut through 5/16" hardwood plywood using the mini-saw attachment.
  • Has almost every feature you want. Part on power cord keeps falling off but not a big deal.
  • Moving on to the performance of this tool. It's the most powerful Dremel at 2 amps.
  • Garbage, just like the last review, my motor seized up.
  • UNK! This is the second unit/motor I have burned up.... will not take any serious wood working other than balsa wood. DO NOT buyany dremel product! Cheaply made and engineered. Is a fire hazard.
  • Noisy at high rpm compared to its small size.
