More than 30 inspection to ensure the delivery of qualified production to the customer.
The testing includes bending resistance, stretching resistance, torsion resistance, impact resistance, alloy hardness test, steel handle hardness test, metallographic analysis, cobalt content test, cutting efficiency, maximum magnetic torque testing, alloy denstity and other testing procedures.
All carbide burrs are soldering by SILVER which is more strength than copper, cause when soldering by silver, the temperature is 800 degree, if COOPER soldering, it's more than 1200 degree. If the tempreature is higher, COBALT is easy evaporation, the shank and head is much strength, it's easy break off.
