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.

Kit Contents

You can just buy the Dremel as a stand alone tool, but I decided to feature a kit, that does include some useful attachments.

  • Dremel 4000 high-performance tool
  • Circle Cutter/Straight Edge Guide
  • Sanding/Grinding Guide
  • Storage Case
  • 30 accessories
  • Manual
Dremel Keyless Chuck

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

Collet Set

Dremel Collet Set

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
