Description
Version:
Special polygon geometry and shank to DIN 6535-HA for use on machines with synchronised spindle drives. With oil grooves; optimal lubrication effect even in deeper threads.
Special solid carbide tool material for high cutting speeds and long tool life. TiAlN and anti-friction coating ensure low wear and low tendency to edge build-up.
With internal coolant supply laterally from the grooves; recommended for through and blind holes.
