You can read this guide we wrote on lapidary work.

Flex shaft attachment

A Dremel flex shaft is an attachment for the Dremel rotary tool range – the 225-01 Flex Shaft Attachment.

The flex shaft attachment has the following benefits over using the standard rotary tool:

1. It is very flexible and smaller than the main shaft, allowing access to tighter or smaller areas

2. The actual shaft has a 5 inch bend, allowing you to work on awkward angles

3. It is very lightweight and gives you greater control and precision – if you hang the main unit up by its hook, you can work with just the flex shaft for long periods without experiencing hand fatigue.

You can check out the flex shaft attachment here.

Dremels are among the most flexible finishing rotary tools you can buy with the extremely wide range of accessories and attachments that perform different functions.

You would justify using a dremel over a hand tool to prevent fatigue, get more power and speed, and also because the dremel is really multiple tools in one.

You can get electric dremels, or cordless dremels that are battery operated and portable.

Electric dremels you simply plug them into a power source, attach your accessory and/or attachment, turn on the dremel, and get to work.

Cordless dremels either have lithium ion re-chargable batteries, Ni-Cd or replaceable alkaline batteries. Insert the battery pack, or replace the batteries, attach your accessory and/or attachment, turn on the dremel, and start working.

The bottom end of the dremel has a spindle lock button, cap (that unscrews to attach attachments), collet cone that your bit/mandrel fits into, and a collet nut that tightens the bit into the dremel tool for use.

The 4000 series has the EZ Change™ mechanism and the 4300 has a 3 jaw chuck.

Before repair, check the following things:

1. That the carbon motor brushes aren’t worn out

2. That there isn’t a problem with the power outlet or batteries you are using

3. That the inside of the tool is clean from debris and sawdust

4. That you are using the dremel for it’s designed purposes (don’t overload it)

5. That you are using the appropriately sized accessory or attachment for the tool

 

Once you have checked those things:

1. Check if your Dremel is still in warranty – if it is, call Dremel and arrange servicing

 

If it isn’t under warranty:

1. You can call Dremel anyway – and pay for a service

2. You can try fix the problem yourself if you decide to

 

To repair the unit yourself (note: our opinion is to always follow Dremel instructions for repair – any repair you undertake yourself is at your own risk):

1. Unplug the dremel rotary tool

2. Remove the plastic cap

3. Depending on the model, there will be multiple screws holding the shaft together – unscrew these screws using the relevant screwdriver

4. You will now have access to the inside of your dremel rotary tool.

1. Hold spindle lock button

5. If your Dremel has the EZ Change™ mechanism, you can change the bit without a wrench.
