Abstract

The drilling crown production process involves cutting slots (2) in the straight piece of strip material (1); fitting and fixing cutting elements in the slots; cutting the strip material to length and bending it to shape to form of a cylindrical drilling head of the required diameter, and welding the ends together. The drilling head is then fixed to the annular end face of the carrier body.
