Iscar 5566757 CCMT20SM IC806 Turning Insert Tialn

Product Description

The ISCAR 5566757 is a solid carbide turning insert in the CCMT style, part of the Isoturn series. It carries an IC806 manufacturer grade with a PVD-applied TiAlN coating engineered for cutting superalloys and titanium. The insert features an 80-degree diamond shape with a positive rake geometry and a 7-degree relief angle. The inscribed circle measures 0.25 inches and the insert length is 0.248 inches. A corner radius of 0.008 inches and an SM chip breaker geometry make this insert well suited to finishing and semi-finishing passes where tight tolerances and chip control are critical. Screw-type holding secures the insert during operation.

This insert is intended for use in CNC turning operations on superalloys and titanium workpieces, material group S per ISO 13399 classification. It is designed for applications where PVD coatings outperform CVD alternatives due to lower cutting temperatures and edge integrity requirements. Typical users include machinists and tool-and-die professionals working on aerospace, medical, and high-performance industrial components where difficult-to-machine alloys are the norm.

Key Features

• IC806 grade solid carbide with PVD TiAlN coating for superalloy and titanium cutting
• 80-degree diamond insert shape with positive rake for reduced cutting forces
• SM chip breaker geometry designed for finishing and semi-finishing operations
• 0.008 inch corner radius for precise edge geometry in tight-tolerance applications
• Screw-type insert holding method for secure, repeatable seating in the toolholder
• Conforms to ISO 13399 standards for tool data representation

Compatibility

Designed as a CCMT-style screw-on turning insert for use in compatible ISCAR Isoturn toolholders accepting a 0.25 inch inscribed circle, 80-degree diamond insert with a C clearance code and M tolerance code.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer torque and seating procedures for screw-type inserts. Ensure the toolholder pocket and clamping screw are free of chips and debris before seating the insert. Power down and lock out the machine spindle before changing inserts. Follow applicable shop safety protocols and manufacturer guidelines for insert indexing and disposal.
