DRILLING TITANIUM Fig. 26 A solid carbide drill from the SOLIDDRILL family, intended for machining titanium

No-setup time
ISCAR’s tools with replaceable heads (for example SUMOCHAM and MULTI-MASTER
families) wholly meet the requirements of the important “no-setup time” principle, as replacing
a worn head does not require additional setup operations. The head can be changed without
removing a tool from a machine, which significantly decreases downtime. The MULTI-MASTER
unified thread connection allows the shank to carry different cutting heads and vice versa,
converting the shank to a universal holder and so reducing both tool inventory and storage.
