How Long Does a Dremel Last?

Dremels, like other power tools do not last forever. But how long do they last? Find out below.

Dremel Lifespan

A dremel can last many years of semi-continuous use. The life of a dremel depends on several factors. The most important ones are how you use it and the material being cut.

Dremels are made for durability and rugged use on small cutting and grinding tasks. Dremel uses materials with longevity and toughness as their goal. Each dremel comes with a 2-year warranty and they provide access to customer support.

Also, always make sure that the cable on your dremel is out of the way so it avoids being cut. Do not use your dremel for long periods of time without inspecting it for any damage or worn parts.

Parts Of A Dremel

A dremel is a tool that consists of a two-speed (rotations per minute) electric motor and an interchangeable bit or attachment. The many available attachments allow the dremel to be used for sanding, routing, cutting, engraving, sharpening, or polishing.

Dremel uses materials with toughness and longevity as their goal. Each dremel hand tool comes with a 2-year warranty and they provide access to customer service.

Dremel Bits Lifespan

Dremel bits will last a certain amount of time depending on what they are used for and how often. Some bits will only last twice as long as others before they need to be replaced. Dremel bits are cheap compared to buying a new tool, but it can become costly if you constantly have to replace them depending on how often you use your dremel.

Dremel And Bit Set
Certain materials will shorten the lifespan of the bit. For example, if you drill fiberglass, the bit will wear down faster due to contact with abrasive glass fibers. Grinding, drilling, or cutting metal too fast or at the wrong speed will also wear out the bit quicker.

Applying too much pressure while using a Dremel will also wear out the bit faster.

The only materials that will not decrease the lifespan of the bit are soft plastics and wood. Cutting or grinding these will allow the bit to last up to several years.

Dremel Battery Lifespan

The dremel battery lifespan is difficult to determine exactly. This can mean the runtime between charges or the actual longevity of the battery.

Dremel uses high quality cells in its batteries. In general, dremel batteries will last for 3 years of constant daily useage, or 6 years of occasional use. A user can expect their dremel battery to last several hundred full charges.

Whether the battery charge will last a longer time will depend on how hard it has to work. If you cut or grind steel and use a lot of pressure, the battery will drain faster than if you try and cut soft woods.

You can notice the battery draining when the RPMs start to decrease. This will happen after about 15-25 minutes of semi-continuous use at one of the higher speed settings.

Dremel batteries take about 45 minutes to 1 hour to fully charge.

Dremel Won’t Turn On?

This can happen from time to time, and no matter what you do the Dremel won’t turn on. The reasons for this include:

  • The Dremel is not plugged in.
  • The battery is drained.
  • The brushes are damaged or clogged up.
  • Stator wires are not making contact.
  • The motor is blocked by grime.
  • The on/off switch is broken.
  • The TRIAC chip is faulty (it forms a part of the variable speed motor controller).

If any of the problems are internal to the Dremel, it will need to be opened up and inspected and these parts will need replacing. A damaged dremel can run more slowly than normal, or not switch on or off consistently.

Dremel Makes Burning Smell?

While running the dremel, it produces a burning smell. What causes this? This is likely due to one of the following reasons:

  • Dust build up in the tool.
  • The brushes are worn out.
  • The motor is burnt out.

Dremel Will Not Hold A Bit?

A dremel will stop being able to hold a bit due to the lock pin and spring no longer functioning properly. So, when you push the button to lock in the bit, it will not fit into the hold on the rotating shaft. The only solution is the replace it by dissassembling the dremel.

Dremel Motor

Dremel Motor Lifespan

A dremel motor can last many years of continuous use if it does not get clogged up by dust or particles. With maintenence when needed, a motor that is slowing down can be repaired. However, by pressing too hard while cutting or grinding hard materials, there is a chance the motor can burn out completely. At this point, the dremel will need fixing or replacing.

In Closing

By taking good care of your dremel you should be able to get the most out of it before you need to replace it. These are some things you can do to make sure that your dremel is not only working properly but also lasts as long as possible.
