2.5.2 SWISSCUT System for Swiss-Type Lathe

Tools for External Threading

The compact SWISSCUT toolholder provides easy and accurate indexing of the insert.
The very stable, tangentially clamped insert can be indexed without removing the screw and
without removing the toolholder from the machine turret. In addition, clamping and releasing THREAD TURNING
the insert can be accomplished from either side of the toolholder. Bottom and rear prisms
provide high stability and precision when turning in alternating directions or where relatively
high loads are applied.

The back clamping option of the SWISSCUT enables the user to clamp the insert in the
holder from the opposite side of the insert.
This B-Type (back) clamping style is enabled by using an insert with thread bushing.
The insert is clamped by a screw that pulls the insert into the pocket by thread bushing.
An O-ring mounted on the screw prevents the screw from falling out of the pocket while the
insert is being replaced. The same tool and insert can be used in both clamping directions.
The clamping design uses a special screw that can be accessed and operated from both
sides of the tool.

The SWISSCUT system is a part of ISCAR’s tools for Swiss-type machines
and small lathes.

• The unique rigid tool design with small insert overhang provides excellent economical results
especially for finishing and precision machining of small parts.
• The SWISSCUT family provides a good solution for practically any miniature part application.
