Iscar 5667743 Milling Insert IC380 Solid Carbide Triangle

Product Description

The ISCAR 5667743 is a solid carbide milling insert designed for use in high-performance face and shoulder milling applications. Identified by ANSI code HM390 TPKT 1003PDR IC380, this insert features a triangular shape with three cutting edges and a positive rake geometry. The IC380 grade substrate is submicron carbide with a PVD-applied TiCN and TiN coating, making it well suited for demanding cutting conditions in superalloys, titanium, and hard materials. At 0.152 inches thick with a 0.3150-inch inscribed circle and a 1/32-inch corner radius, it is a right-hand, single-sided insert held in place by a screw-on clamping method.

This insert is intended for use in the ISCAR HELI3MILL cutter series, specifically HM390-10 compatible toolholders. It targets production machining environments where superalloys and titanium components are common, such as aerospace, power generation, and medical manufacturing. The PDR chip breaker and helical cutting edge style support chip control and reduced cutting forces during milling of difficult-to-machine materials. Licensed machinists and CNC tooling specialists are the primary installers and end users of this insert type.

Key Features

• IC380 submicron carbide grade with PVD TiCN and TiN coating for extended tool life in superalloys and hard materials
• Triangular insert shape with three usable cutting edges per insert
• Positive rake and helical cutting edge style reduce cutting forces and improve chip evacuation
• PDR chip breaker geometry designed for controlled chip formation in difficult materials
• Right-hand cut, screw-on insert holding method for secure seating in the toolholder
• Conforms to ANSI and ISO 13399 standards for insert identification and interchangeability

Compatibility

Designed for use with HM390-10 series cutter bodies in the ISCAR HELI3MILL milling platform. The insert size code 1003 and ANSI designation HM390 TPKT 1003PDR IC380 govern toolholder compatibility. Verify cutter body pocket geometry before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert fully into the pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using the appropriate Torx or hex key. Inspect the pocket seat and clamping surfaces for chips or debris before seating a new insert to prevent seating errors or premature edge failure.
