The best Dremel bit for cutting metal for most rotary tool users would be a cut-off wheel, or cutter bit.
Cut-off wheels are more for straight cuts and cutting off sections of either solid, or sheet metal.
A cutter bit is used more for cutting into metal for metal shaping, cutting curved lines and creating holes in metal/steel.
As we mentioned in our Dremel tool guide for cutting metal, keep in mind the Dremel is a finishing type rotary tool best suited to thinner and less heavy duty metal cuts than say a die grinder, angle grinder or circular saws for example.

What Is A Dremel Bit For Cutting Metal?

Types of Dremel Bits For Cutting Metal

Some cut off wheels are designed specifically for cutting metals, while other will cut metal and other materials like wood or plastic.
Cut off wheels are made with different materials and grit, like for example the cubic boron nitride grit wheels which are much stronger wearing than the fiberglass reinforced wheels.

Diamond cutter bits on the other hand can be used on hardened steel, and used for fine detail work, cutting, engraving, carving, touch-up and finishing.
What Is A Dremel Bit Used For When Cutting Metal?
Cut off wheels can be used for cutting up to roughly 1/2 inch nails, screws, bolts, nuts and other solid metal objects of a similar thickness
Cut off wheels can also be used for cutting straight lines in sheet metal

Diamond cutter bits are more for cutting into the surface of hard metals e.g. engraving and carving
How To Choose A Dremel Bit For Cutting Metal
- Make a list of the metal cutting tasks you want to carry out
- Make a list of the relevant wheels or bits you’ll need for your tasks
- Check what size bit shanks your Dremel rotary tool accepts – get the proper size collet if you don’t have it. If you have the 3 jaw chuck system, the bit should fit regardless of the shank size
- Decide if you want a bit kit/set, or to buy individual bits
- Determine if you need to get a mandrel for the wheel or bit you want to buy
- Buy the suitable bit kit or individual bit for your task/s by looking at what each bit type is designed for, and considering the metal cutting you want to do
Features To Look For In A Dremel Bit For Cutting Metal
What material and grit is the wheel or bit made out of (e.g. diamond, steel) – this effects sometimes the hardness of metal you can cut
What is the bit designed for – what range of tasks, and what range of materials can it be used for and on?
What is the shank diameter (determines what size collet you will need if you have a collet system on your Dremel tool)
How thick and wide is the wheel? Determines what you can cut, and how quickly
What shape is the bit head? (effects the type of work you can do)
Do you need a mandrel to use the wheel or bit?
Is the bit Dremel, or Non Dremel brand? Dremel brand bits are generally high quality, and obviously designed to fit with Dremel tools
How To Use A Dremel Bit For Cutting Metal
- Look at what sort of bit mechanism your rotary tool has – collet system, or chuck (3 jaw) system? If Dremel engraver tool, just decide if you want the carbide or diamond bit equipped in the tool
- On the rotary tool, If chuck system, it should generally fit all bit/wheel and mandrel shank sizes
- If collet, look at the size of the bit shank or mandrel for the wheel/bit you want to purchase, and make sure you have the matching sized collet
- Secure the wheel/bit in the rotary tool
- Begin cutting metal (with appropriate PPE – glasses, hearing protection, spark shield etc.)
