Working Advice
Grind chiselling tools against sanding discs, e.g. aluminium oxide, under a steady stream of water. Make sure that the cutting edges show no annealing colours; this will impair the hardness of the chiselling tools.
To forge a chisel, heat it to 850–1050 °C (pale red to yellow).
To harden a chisel, heat it to approx. 900 °C and quench in oil. Then, leave it in an oven for approx. one hour at 320 °C (annealing colour: pale blue).

For better control and precise positioning, the power tool starts at a low speed and then increases to the set speed.
Adaptive Speed Control is started automatically when the chisel is engaged with the work area during the chiseling application.
When the tool is removed from the chiseling application, the speed is reduced after a time delay.
