Bosch Self Sharpening 40mm Chisel

A self sharpening SDS spade chisel, what a good idea, Bosch have very cleverly designed this SDS chisel so that in use it resharpens itself and that it will constantly have a high material removal rate. 40mm wide these chisels have gone through an inductive hardening process which ensures they are extremely resistant to deformation and make them very hard wearing.
