What Is A Dremel Drill?
Dremels might drill in two main ways:
1. With Drill Bits
The Dremel rotary tool takes drill bits.
One example of a drill bit is the 664DR Diamond Drill FlipBit, which can be used on glass, ceramic wall tile, glass block, stone, and glass bottles, for enlarging holes or making small cuts.
2. With A Dremel Workstation
Dremel also has the Dremel workstation which turns a rotary tool into a drill press.
A Dremel using a drill bit can use a Dremel Workstation at the same time too.

What Is A Dremel Flex Shaft?
Dremel offers two main types of flex shafts:
1. Flex Shaft Attachment
Dremel has the 225-01 Flex Shaft Attachment.
The flex shaft attachment has the following benefits over using the standard rotary tool:
– It is very flexible and smaller than the main shaft, allowing access to tighter or smaller areas
– The actual shaft has a 5 inch bend, allowing you to work on awkward angles
– 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.
2. Flex Shaft Tool
Dremel also makes a flex shaft tool, a high torque/power lower speed tool – the Dremel Fortiflex 9100.
This tool in particular might be good for wood carving.
What Crafts Can You Do With A Dremel Rotary Tool?
Dremel rotary tools are generally good for most finishing, crafting, and lighter DIY type activities.

When … Dremel?
When To Use A Dremel?
Dremels might be for lighter and smaller DIY type and finishing type activities.
When you consider that most Dremel rotary tools have less than 3.0 Amps, you can see why.
When to use a Dremel depends on the tool you get, and the bits and attachments you use with the tool.
Larger and more demanding tasks that involve cutting, grinding, sanding and the like, are ideally carried out with a die grinder or angle grinder.
Dremel type rotary tools are high speed, low torque, and low power compared to die grinders.
Where … Dremel?
Where To Buy A Dremel?

Places like the Dremel website, Amazon, Home Depot, and local home and hardware stores might all sell Dremels.

How … Dremel?
How To Use A Dremel?
It depends on the individual Dremel tool and what exactly you want to do with the tool.
But generally, it might involve:
1. Decide on the activities you want to carry out, and choose a suitable tool
2. Choose a bit and/or attachment to use with the tool
3. Attach the bit or set up the attachment
Essentially this involves untwisting or keying the cap or chuck (or mechanism) that holds the bit, and inserting your bit or attachment.
You then have to tighten the cap or chuck to make sure your bit or attachment is secure
Read this guide about the different Dremel chuck and collect systems for attaching and detaching bits from a Dremel tool
If a chuck system, most bits and attachments should fit the tool
If a collet system, fit the proper sized collet for the bit you want to use
For example, a Dremel might have 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.
An EZ Twist system for example doesn’t require a wrench for bit changes, but does require that you switch the collet size out when you have bits of different shank sizes. Switch the collet out for the size of the bit shank you are using
4. Use the tool as per the manufacturer instructions
This might include things such as adjusting the speed, and so on
If the tool starts getting hot, break to allow the tool to cool down so you don’t overload the motor
5. Change the bits and attachments over as necessary for different tasks
For bits like sanding pads that wear out more easily than others, make sure you have spare bits available in your kit.
6. Whether it’s a corded Dremel, or a cordless Dremel impacts whether you need to worry about charging or not
Obviously a cordless Dremel will require battery charging for lithium ion rechargeable batteries, or replacement for the batteries that aren’t rechargeable
How Does A Dremel Rotary Tool Work?

How Much Is A Dremel Tool?
It depends on the model, and where you buy it from.
Some might be under $100, and some over.

How To Repair A Dremel Rotary Tool?
Before repair, you might follow Dremel’s instructions on maintaining your Dremel tool so you can take proper care of it.
You might also 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
6. A potential issue when the shaft isn’t spinning is that the coupling has worn down (the little ring between the shaft pieces).
Check this to see if it’s broken and whether this is the issue.
Repairs & Warranty
Your Dremel may or may not still be under warranty.
Check the warranty and the date you purchased the tool to find out.
You might contact Dremel if the tool is under warranty to ask about your options for repair.
If the tool isn’t under warranty, you have a decision to make about what you’ll do with the tool.
How To Change The Dremet Bit Or Attachment
It depends on the bit changing system that is used on the Dremel.
– Some tools might require wrench changing
– Some tools might have the EZ Twist Cap System that doesn’t require a wrench for bit changing
– Some tools have the 3 Jaw Chuck
In general, a bit changing process might look like the following:
1. Hold spindle lock button
2. Untighten the collet nut with the wrench tool
3. Change over the bit by removing the current bit, and placing the mandrel/spindle of the new bit, or just the new bit into the collet cone.
A wheel usually comes with a mandrel you attach, whilst a bit has a permanently attached spindle.
4. Tighten the collet nut with the wrench tool and check the dremel bit isn’t loose.
Release the spindle lock.
5. If your Dremel has the EZ Change™ mechanism, you can change the bit without a wrench.
6. If your Dremel has a 3 jaw chuck – you may or may not need a tool key to change bits.
To change a dremel attachment, you can:
1. Remove the plastic ring/cap
2. Unscrew the current attachment
3. Screw on the new attachment
