Why Is My Drill Overheating – My Secrets Fix

You have commonly encountered the problem of drill overheating during your work. There could be plenty of reasons that have led to this issue, but mostly it is too much pressure or heat that can affect your drill. 

With the advancement of technology, we have today one of the finest tools at our disposal that makes our life easier. But they also come with some critical factors that can impact the power or stability of the drill. 

The most important thing to remember is to use the drill properly. Before starting any project, you should have the experience and knowledge of the tools. So you can identify the problem and fix it immediately to keep your tools safe for a long time. 

Why Is My Drill Overheating

Drills can overheat or stop working anytime and anywhere. The first thing is to allow the tool to cool down before moving on to the other fixes. Let’s discuss the reasons for the overheating in detail. 

Old Brushes Of The Drill

An old brush is an overlooked problem that can happen in used drills. The brushes are mostly made of carbon or copper, which is why drills get overheated so quickly. Over time, the brushes are scratched because of the friction that requires lubrication for a quick fix. 

Applying Too Much Pressure

Is your brushless drill smoking? It is important to remember that you shouldn’t apply too much pressure when you are using the drill. Start with slight pressure and let the tool run on its own and get the job done. The motor will run fast and pull more electricity if you apply additional pressure. It can overheat the drill often and lead to other technical issues. 

Continuous Use Of The Drill

You might have been using the tool for a long time. It can negatively impact the stability and power of the drill. So, ensure cooling drill bits after regular intervals during the work for a better experience. 

No Use Of Lubricants

Lubricants are vital for your tools, especially when it comes to your drill. It reduces friction and keeps the drill bits and brushes reliable for continuous use. 

Covering Of Ventilation Holes

Another major reason for the overheated drills is the covering of ventilation holes with our hands. It is a common mistake we make when using the drill. But, it does not allow the heat to pass, which overheats the drill quicker and affects your tool. 

Overload Of Drill Due To Torque

Every drill has different torque that determines the strength of the drill. It could be perfect for one job but not the rest, where you need more power. We typically prefer applying pressure rather than using the correct drill with the required torque to get the job done. 

Common Mechanical Problems

Is your corded drill smoking? There could be some mechanical problems with the bearings, wheels, and shaft overheating the drill. You should get it checked immediately by an expert or do it yourself if you have the experience. 

The Electrical Path Is Too Short

A drill has both electrical and mechanical components. Drill smoking can happen when the electrical path is short, and there is no proper flow of the current through the circuit. It can damage the wires, overheat the tool, and even give severe shocks to the user. 

Drilling At The Wrong Angle

There is a specific angle for every drill and the cutting you are doing. For efficient and effective results, the correct angle is critical. Otherwise, in many cases, like woodworking, there could be a chance of fire because of overheating. You can avoid it by using the tool at the right angle. 

How To Avoid Overheated Drill?

  • Do not apply too much pressure, and let the drill work smoothly. 
  • Avoid covering the ventilation holes and let the heat pass out of the tool. 
  • Do your complete research when you are buying a drill. Many brands with unique features and power ranges are subject to your use. 
  • Check the torque and RPMs always if you want a more robust drill. 
  • Clean your drill regularly to ensure its protection from dust. 
  • Keep it lubricated to avoid any mechanical problems.
  • Change the brushes frequently, especially when they are only a quarter-inch long left in the drill. 
  • Take breaks between the work and let the machine cool down.
