Of the many rotary tools available,the Dremel Moto-Tool is by far the most popular. For drilling,grinding and polishing it has no match!
I have owned a Dremel rotary for many years and i cannot imagine a workshop without one!
In fact I have a total of 3! I use it primarily for drilling small holes (up to a maximum diameter of 1/8") and for cutting and grinding fiberglass (primarily in f/g cowls).
The Dremel is variable speed and is 110/120V. If I use a battery powered tool it always needs charging at the moment I need it!
When it comes to cutting piano wire, especially the thicker stuff, then the Dremel, with a re-enforced cutting wheel installed is the only way to go! Be sure to use safety glasses and watch out for the sparks!
You will also find uses for this tool around the home. Once you have one, various cutting and grinding jobs will now become possible. Just remember it is a high speed, low torque device so heavy duty jobs are not it's strong point.
You can just buy the Dremel as a stand alone tool, but I decided to feature a kit, that does include some useful attachments.
A lot of the 30 accessories you will never or very occasionally use.
If you think you will do a lot of drilling,one extra accessory I would take a serious look at is the Dremel Chuck.
The collet set is an alternative, but the chuck is much quicker and more conveniant
The Dremel 4486 MultiPro Keyless Chuck is in stock. Price: $8.99
I was surprised to learn that the unit does NOT come with a collet set! It includes just the one collet for 1/8"diameter shanks. All the accessories have 1/8" diameter shanks but if you need to drill smaller holes than 1/8 " you are out of luck!
All 3 of my old Dremels came with a set of collets, so I do find this a serious over site by Dremel. You can buy a set, so remember to pick up a set when you buy your 4000
The set comes with 4 collets (1/8",3/32", 1/16" and 1/32") and a collet nut. Note the rings on the bottom of the collets signifies the diameter.
The Dremel Quick Change Collet Nut Kit is in stock. Price: $14.99
I selected these 3 videos to give you a good idea of what this tool is. It is not the kit as described here but does show the basic tool well.
After reading a lot of customer reviews, it was apparent that there is not much wrong with the Dremel tool! Very few complaints were found.
I did come across this review of 6 tools including the Dremel, so please take a look here for this review from Popular Mechanics
