Iscar HeliTurn

ISCAR’s HELITURN system features a unique, double-sided insert with 4 cutting edges for Fast Metal Removal (FMR) turning. The new HELITURN is a tangentially clamped insert with a unique helical shaped cutting edge, useful for large depths of cut and higher than normal feed rate.

The LNMX…-HT HELITURN insert is screw-clamped into the SLANR toolholder and supported by the TLN ..-HT carbide seat. This seat has ground surfaces on the top and bottom, to ensure perfect contact of the insert with the toolholder.

The upper rake face of this insert is mounted level with the top of the toolholder to enable chips to flow across the insert, without being disturbed by clamps or the toolholder body. The 4 curved helical cutting edges ensure positive radial rake angles and soft penetration into the material being cut. The lower forces and smaller loads ensure better tool life, higher stability and the ability to use very large depths of cut and higher feeds. The chipformer (with small bumps), deforms and breaks the chip into rib type curved segments which can easily be removed from the cutting area.

The insert has a frontal clearance angle of 3.7° with a 6° side clearance angle to allow machining to a 90° shoulder.

Depths of cut up to 8 mm [.315”] and facing depths to 3.2 mm [.126” ]
at up to 1.2 mm/rev [.047” IPR] are achievable with HELITURN.
