THREAD TURNING Perpendicular Holder for Swiss-Type Lathes
Solution for Internal Threading
ISCAR designed perpendicular holders for PICCO-CUT inserts used on Swiss-type
machines. Unlike the round shank toolholders (PICCO/MG PCO), which could be mounted
only on the end units, ISCAR designed perpendicular square-shank tools to be used on
cross slide units.

Each toolholder has been designed to fit several PICCO insert shank diameters. The
toolholder features an internal coolant hole directed to the machining area. This reduces
temperature and wear, and improves chip evacuation. The supplied coolant fitting allows
for a maximum coolant pressure of 10 bar. If a higher coolant pressure is required,
a suitable fitting/pipe should be used. Very rigid clamping ensures stable and efficient
threading machining.
On ISCAR tools, it is possible to mount the insert into the pocket from the frontal side and
from the top side. This is a major advantage on machines where it is not possible to index
the insert from the front and the tool must be removed from the machine (note: standard
round tools such as drills and taps can also be clamped).
