Iscar 5540005 Vcgt Turning Insert 3/8 Ic Solid Carbide

Product Description

The ISCAR 5540005 is a solid carbide turning insert designed for precision external and internal turning operations. Manufactured to ISO 13399 standards, this insert features a VCGT style with a 35-degree diamond shape, providing a sharp cutting geometry for clean material removal. The IC20 uncoated grade is engineered for applications requiring consistent edge performance without a coating layer. At 16.60 mm in insert length and a 3/8 inch inscribed circle, this insert fits a range of compatible screw-lock toolholders used in production turning environments. The positive rake and AS chip breaker geometry support controlled chip flow across multiple workpiece material categories.

This insert is suited for turning operations on cast iron, non-ferrous metals, and heat-resistant superalloys, corresponding to ISO workpiece material groups K, M, and N. The AS chip breaker designation makes it appropriate for light to medium finishing passes where surface finish and dimensional accuracy are priorities. It is installed in CNC turning centers and manual lathes by machinists and tooling technicians working in job shops, production machining, and aerospace component manufacturing. The maximum depth of cut is 3.00 mm, keeping it in the finishing and semi-finishing range.

Key Features

• VCGT insert style with 35-degree diamond shape for tight-clearance turning
• IC20 uncoated solid carbide grade suited for K, M, and N ISO workpiece material groups
• AS chip breaker promotes controlled chip formation during finishing cuts
• Positive rake geometry reduces cutting forces on the workpiece
• Screw insert holding method for secure, repeatable seating in compatible toolholders
• Manufactured to ISO 13399 standard for tooling data compatibility

Compatibility

Designed as an OEM-style replacement insert for VCGT-style screw-lock turning toolholders accepting a 3/8 inch inscribed circle, 3/16 inch thick diamond insert with a G tolerance and C clearance code. Belongs to the ISCAR Isoturn series.

Installation Notes

Installation is performed by machining technicians using the appropriate Torx or hex key for the insert clamping screw. Power down and de-energize the machine spindle before changing inserts. Ensure the insert pocket and seating surface are clean and free of chips before seating the new insert. Follow the toolholder manufacturer guidelines for screw torque and insert orientation.
