Dental Screws
For rough OD (outer dimension) turning, ISCAR
developed a SWISSCUT compact tool designed for
Swiss-type automatics and CNC lathes,
which enables reduced setup time and
easy indexing without having to remove
the toolholder from the machine.
Another option features SWISSTURN
toolholders, with a clamping mechanism
to optimize insert clamping and replacement
on Swiss-type machines, and JETCUT high
pressure coolant tools. SWISSCUT tools perform
the turn threading.

CHATTERFREE endmills are utilized for the slot
milling stage to maximize stock removal rate,
eliminate vibration and reduce cycle time. The
ground geometry provides excellent surface and tool
life, while machining at high material removal rates.

PENTACUT parting and grooving inserts perform
the cut-off operations. With 5 cutting edges and
very rigid insert clamping, PENTACUT is a
stronger insert for higher machining parameters
particularly on soft materials, parting of tubes,
small and thin-walled parts.

SWISSCUT tools are used for face and
OD turning (screw head turning), and
SOLIDDRILL solid carbide drills, with
3xD and 5xD drilling depths and right-
hand cut, for the drilling. The drills feature
coolant holes.

The thread milling stage uses SOLIDTHREAD
thread mills, whose short 3-tooth cutting zone with
3 flutes and released neck between the cutting
zone and the shank enable precise profiles and high
performance. The extremely short profile
exerts a low force which minimizes tool
bending, facilitating parallel and high
thread precision for the entire length.

Solid carbide SOLIDMILL endmills with 2
flute, 30° helix medium length, perform the key
head milling operation.
