Felo bits are made of chrome-molybdenum-vanadium steel, hardened in oil to a hardness of 60-64 HRC, which prevents chipping of the slot and extends the service life of the bit. Each individual bit is tested under a voltage of 10,000 volts to ensure safe work under voltage. Country of origin - Germany.
