Sharpening chisels
Since good results can only be achieved using sharp chisels, it is important to
sharpen tools in good time. This prolongs the life of your tools and ensures high
efficiency.
Grind chisels using grinding wheels (e.g. corundum). Keeping the chisels wet
using a steady supply of water. Refer to the drawings below for recommended
values. Make sure that no annealing colour appears on the cutting edges,
otherwise the hardness of the chisel will be impaired.
