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.

Note:

For use on synchronised spindles, the GARANT quick-change tapping chuck No. 338100338121 with minimum length adjustment (MLA) ensures very high process reliability.
