A Dremel is a type of rotary tool that is used for a variety of purposes such as sanding, polishing, sharpening, cutting, grout removal and among others. Dremel is not entirely a tool, but a company that manufactures rotary tools.
In this article, we shall focus more on the cutting capabilities of the Dremel rotary tool. You can use it to cut through materials such as aluminum or any other sheet metal. Keep in mind that you will require specific bits or attachments depending on the material you intend to cut.
Depending on what you would like to cut and its thickness, you can decide between a cut off wheel or a 1-1/2-inch cutoff wheel which is known to cut sheet metal that is thin with so much ease. When you decide to purchase a Dremel rotary tool, it comes with a kit that has different attachments for you to choose from.
In this article, we shall look at how to use a Dremel to cut metal most kinds with ease. But first, let us look at some of the materials you will require for this exercise.
Things you will need
Safety Equipment Required
The first thing to do before you use the rotary tool is to perform a safety check. Some of the safety equipment is listed below
This is for protecting your hands from the excessive friction that would come from the metal being worked on as a result of too much heat.
They allow easy visibility when working, as well as protecting your eyes from sparks being blown around.
They protect you against fine particles of groundwood debris flying around.
Ear Plugs or Muffs
This offers protection against excessive noise that comes from the rotary tools when in use.
These shoes guide against falling debris that otherwise burns or breaks your feet and toes. If you may not have this, any closed shoes could work.
How To Use A Dremel To Cut Metal Step-by-Step Guide Line
Step 1: Preparing the Tool and Work Space
Cutting metal can be quite a daunting task. This is because of all the sparks that tend to fly around and the fumes that come out when cutting. It is, therefore, best to work in a well-aerated area to allow fresh air in. Because you will need to clamp the sheet metal, it is important to have a workbench and clamp for this.
When preparing the tool, use a wrench that is provided during the purchase of the rotary tool, or better yet, you can purchase it separately. Remove the drill head with the wrench. Insert a cutoff wheel you desire depending on the thickness of the metal and the precision you would like to attain.
Step 2: Marking the Area for Cutting
Using your pencil, you can mark the area you would like to cut in order to ensure you remain within those lines and avoid damaging your material. Dremel rotary tools are best for small cuts and incisions, which is a good reason why marking is important whether you are doing a straight or curved cut.
You can use low adhesive tape strips in place of a pencil to mark the area to be cut. This is all a matter of preference.
Step 3: Cutting the Metal
Before you start cutting, position the tool in such a way that the cutting wheel is in a perpendicular state to the metal being cut. Make sure you hold the Dremel with both hands for stability over the marked area.
Next, turn the rotary tool onto a medium or high speed to give you the right amount of power required to cut out or through the metal.
Using a firm but low pressure, dig into the metal. Remember not to cut all the way through during the first cut. Thereafter, go over the area again until you get to the required depth you desire as you move along the line of the marked area.
If you would like to make a more accurate cut, you can install a smaller bit or attachment for this. Be keen on the sparks that fly around as they may stick on you or another person. This is why it is important to have your safety equipment during this exercise. Also, do not touch the cut area immediately because it may be too hot and sharp.
Step 4: Smoothening the Cut Area and Finalizing
Install a grinding bit and grind the area you have cut to smoothen it out and make it even. Ensure you use less force when doing this to avoid damaging the metal surface. After grinding, follow up with sanding for an even smoother edge.
