Drill cobalt fi 5,5 Inox
Drill 5,5 mm cobalt HSSE Inox. Professional cylindrical twist drill according to the dimensional standard NWKa, DIN 338, designed for drilling through-holes and blind holes with a diameter of 5.5 mm. It has strong ground cutting edges that are resistant to impact and lateral forces, as well as spiral grooves used to guide chips up the drilled hole. The drills in question are made from modern high speed steel with about 5% cobalt - HSSE. This is a very modern material used in the production of cutting tools used in large locksmith shops. The properties of the steel in question make it possible to achieve high cutting efficiency and thus reduce working time. In addition, cylindrical drills of this type are extremely durable and resistant to thermal extremes and other harsh working conditions. Even in the case of high temperatures (up to 670 degrees) generated during high-speed cutting, the drills retain their high properties and allow precise drilling of holes (with low roughness). Drill 5.5 mm cobalt is recommended for all professionals.
