Genuine Problems That Bosch Tools Mostly Have 

bosch tools

Bosch is one of the market leaders in power tools, the company has built and maintained a name in the market, but in the last few years, some problems have been detected by users in almost every other product of Bosch. However, there are also reasons from the users’ side which contributed to the improper working of Bosch tools, and these are as follows;

  • The working instrument is doing is not what that particular hammer is supposed to do
  • Gun not having a proper storage place 
  • Heavy working hours being carried out with the hammer even without any resting periods
  • Maintenance not done timely 
  • Overheating of the instrument due to continuous usage

Regardless of the above reasons, more factors contributed to the product breakdown. These are of two types, one is mechanical, and the other one is electrical, and these factors are from the Bosch side as they are the failures of Manufacturing. Let’s have a look at these factors as well.

Mechanical Factors 

The puncher does not work, but the drill is still a sign of some mechanical issue with the hammer, as maybe the cage of the rolling bearing has collapsed, the barrel has collapsed, or the clutch has gotten some technical problems with its splines. 

In addition, the other reason could be that hammer has not stopped drilling, but the drill has changed and is not the same as before, which could be due to multiple reasons.

The puncher is not working well, or the clutch may not be able to connect with the pressing; locking gears can also be the reason behind the undefined working of the drill, and the other reasons include lack of power in the electric punch, which leads to drill stoppage or slowing. 

Electrical Factors 

Electrical factors mainly include the aspects related to electricity; burning of the clutch, motor or switch especially causes the breakdown of the hammer, and this could happen due to multiple reasons.

They were overheating the hammer due to the use of the hammer for longer hours without productive breaks, which may cause the motor or switch to get heated to the level that they may spark or burn.

The rotor has some areas, are called reservoir areas; there are chances of burning and short circuits in these areas, so that an electrical loss could happen due to problems with the reservoir areas of the rotor hammer.

The main reason for slowing down hammer drills or other problems is the non-maintenance of brushes on time. As meetings of the hammer require proper maintenance every 70 hours, failing to do so will ultimately lead to the abovementioned issues.

How To Differentiate Between Mechanical And Electrical Factors

The easy way to differentiate between mechanical or electrical faults is to look for the symptoms. If there is a smell of burning, unnecessary sounds, the hammer is not working as speedily or productively as it used to be, or the hammer is heating up very quickly. These are the symptoms indicating a mechanical fault in the product.

Electrical Factors

While for electrical faults, a very unpleasant and strong burning smell will erupt from the hammer, in severe cases, a spark may light out from the hammer leading to some unbearable burning smell.

Common Problems Which Any Hammer Can Have With Their Respective Solutions

Rotary hammers are specifically designed for heavy cuttings such as cutting tiles or concrete. While doing such tasks, most of the time, hammer drills cause troubles which need to be resolved first for other workings. Some widespread problems which any rotary or hand hammer can face have been discussed below; 

Tile Or Concrete Split 

Tile or concrete can split or crackdown as a result of hammer drilling due to heavy pressure at once. To avoid this, pressure from the drill to the cutting material should release slowly and gradually so that the cutting material may not get damaged

Drill Stops Suddenly 

Drills can stop while working due to two leading causes. One, if any, the rock gets into the routine and controls the working of flutes. Another is the material which is supposed to be cut down by the drill is not enough for cutting; more material should be added under the hole range of training for better working. This can be prevented in the following ways; 

  • Rock can not be broken down in the drill; in any case, it should be taken out from the training to work. Try to insert some nails or anything sharp-pointed in the exercise to remove the rock to resume operating the drill
  • Constantly watch for the material that is under the drill and try not to let it finish; add new material before completing the ending


Spawling is very common while using a rotary hammer, and it is the material or pieces of the tile or concrete that fly over while the rotary hammer drill is doing its work.

Spawling should be controlled to prevent injuries, as these particles are tiny and sharp enough to cause damage. To prevent spawling, a rubber cap is available in the market, which if placed at the chunk end of the hammer drill then it can control the breaking material to spread in the surroundings. Moreover, the drill’s pressure must be reduced in case of excess spawling.

Bit Jams In The Drill

At times, bit pieces get stuck in the drill, and this causes the rotary hammer drill to stop working. To avoid such an issue, the training should be stopped immediately and cleared out before resuming the exercise working again. There is a wrench available in the market with the name of Stillson wrench, which is specifically designed to resolve this issue of the drill.
