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 4000-6/50 Variable Speed Rotary Tool
  • The Dremel tool itself is great and I really appreciate the variable speed settings.
  • It has plenty of power and the adjustable speed lets you tune the Dremel to the task at hand.
  • But this Dremel is powerful and has adjustable speed setting. It took me awhile shopping online and reading reviews to find a Dremel that would meet all my needs and this is definitely the one.
  • The tool doesn't have a lot of torque, so you need to let it operate at high speeds and let the rotational speed do the work.
  • I feel that it is worth the money to get your Dremel with a varible speed control. Speed does matter and it gives you something to play with when you get bored or just thinking things over.

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 4000-6/50 Variable Speed Rotary Tool
  • This unit works good. I previously had one of the original Dremels and finally had to replace it. They have made some real improvements. Nice size, weight and feel.
  • Not a commercial rotary tool but a light weight all around small task tool as in hobbyist tool.
  • It makes it hard to do some of the finer projects I was wanting to do because it's weight and size makes it awkward to handle.
  • The flex shaft is particually nice since it allows you to have a light weight tool in your hands for detail work.
  • I use this for my 2 Dremel work stations, drill press and router table, has the power the cordless doesn't, but the cordless is used more often for it's portability.

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 4000-6/50 Variable Speed Rotary Tool
  • Comes with some nice attachments, can't wait to use the sharpener on my mower blades and see how well it works. Very pleased
  • This specific unit is extremely powerful, light, durable, and not too noisy. It includes a few bits which work well, but I wish i included more for the level of the kit.
  • The better tool ever for home or diy, probably doesn't works for heavy duty works. but so much accesories can be attached.
  • The tool is great the accesories are good but the only thing this that it did have the disk to cut wood that is my only fault with this product.
  • Great product; love that I finally have the full set with all possible attachments included in the package.

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 4000-6/50 Variable Speed Rotary Tool
  • It feels solid in my hand and has good power for what it does.
  • As with all Dremel brand rotary tools, this is excellent construction, power, and versatility.
  • So I love the dremel (when it was working) great power, easy to use, simple, did everything I needed it to do, except power back up it just stopped working out of the blue and only used it a few times.
  • Be aware that you will lose some power with this extension, there were times when drilling and cutting that it would seize and I would have to turn it off, remove the tool, and start again moving slower.
  • It has plenty of power and the adjustable speed lets you tune the Dremel to the task at hand.
