In general, bending and levering lead to failure of the chisel tool and should be avoided. In general, with pointed and flat chisels, it must also be ensured that the tool changes position after approximately 3 seconds, because every flat and pointed chisel tends to jam. The SDS-plus and the SDS-max shank must be greased to prevent heating of the shank and thus its failure.
In principle, even reinforcement can be cut through with a spade and flat chisel. When doing so, it must be ensured that the chisel is sharp and that the reinforcement is firmly anchored and does not tend to vibrate.
To prevent the machine from jumping, high pressure should be exerted on the rotary hammer drill bit during spot drilling and the machine should be set to the hammer position. Select the pressure on the machine so it does not jump and can work quietly. This is ensured by a pressure of 15 kg to 25 kg.
The rotary hammer drill cannot work properly with excessive pressure. This reduces the service life of the rotary hammer drill and results in increased heat input at the chisel.
With too little pressure, the machine jumps. This can lead to injuries.
Our chisels must not be re-hardened. In principle, re-hardening is possible but should only be carried out by qualified specialists. This should only be done if the chisel has lost its hardness due to overloading.
Any heating, friction or defects can lead to a local, new increase in hardness or a notch that can result in failure of the chisel tool.
