Iscar 6405445 Threading Insert Carbide IC1008 15-28 Tpi

Product Description

The ISCAR 6405445 is a carbide threading insert designed for external thread-turning operations on Swiss-style CNC lathes and turn-mill centers. Part of the IscarThread Swisscut series, it carries the IC1008 submicron carbide grade with a PVD coating for extended wear resistance at high cutting speeds. The insert covers a pitch range of 0.90 to 1.70 mm (15 to 28 TPI) and cuts a partial-profile 60-degree thread form. The SCIR-style geometry and MT chipbreaker work together to produce clean thread forms while managing chips in tight Swiss-type machining envelopes. Licensed machinists and CNC tooling technicians are the primary users of this insert.

This insert is suited for external threading on small-diameter turned components typical in medical, aerospace, and precision instrument manufacturing. The SCIR22 insert size fits compatible ISCAR IscarThread Swisscut toolholders designed for the 22 insert size. The right-hand cutting configuration addresses the most common threading direction in Swiss-type sliding-headstock lathes. It is appropriate for threading a range of materials where IC1008 PVD-coated submicron carbide is the specified grade.

Key Features

• IC1008 submicron carbide grade with PVD coating for wear resistance and edge toughness
• Covers 0.90 to 1.70 mm pitch range (15 to 28 TPI) in a single insert
• Partial-profile 60-degree included angle for external threading
• MT chipbreaker geometry suited to the confined chip-evacuation conditions of Swiss-type machines
• Right-hand cutting orientation, SCIR insert style
• Corner radius of 0.1 mm (0.0040 inches) for precise thread root geometry
• Compliant with ISO 13399 tooling data standards

Compatibility

Designed for use in IscarThread Swisscut series toolholders accepting the SCIR22 insert size. Verify toolholder seat and clamping compatibility with ISCAR toolholder documentation before use.

Installation Notes

Insert seating and clamping should be performed by a qualified CNC tooling technician following the toolholder manufacturer's clamping torque guidance. Power down and lock out the machine before changing inserts. Inspect the insert seat and clamping screw for debris or damage before seating the new insert. Handle carbide inserts with care to avoid chipping the cutting edge prior to installation.
