Broca multiaplicación Of high performance indicated for a wide range of materials
CoroDrill 460-XM is done of hard metal of fine grain, to guarantee an excellent combination of hardness and tenacity, and provide a big resistance to the wear and a prolonged useful life of the tool. Likewise, his coating has of a treatment of special finishing that reduces the coefficient of friction. The strong design of network provides an excellent transversal strength that, in combination with the design of the channel of desahogo, optimises the evacuation of shaving. Besides, thanks to his design of low strengths of drag and his good capacity of centred, the angle of tip of 140º is ideal for the operations of taladrado in multiple applications.
The broca presents , in the standard version, in a range of diameters of 3–20 millimetres (0.118–0.787 inches) and lengths of 2–5 × the diameter of the broca (DIN 6537 K and DIN 6537 L). The tolerance of the possible hole is of IT8–IT9 and it is available with refrigerante inner and external.
