Iscar 5540018 Turning Insert Ccgt 3-2-AS IC20 Solid Carbide

Product Description

The ISCAR 5540018 is a solid carbide turning insert in the CCGT 3-2-AS geometry, part of the Isoturn series. It features an 80-degree diamond shape with a positive rake angle and 7-degree relief, making it well suited for light finishing and semi-finishing cuts on a wide range of workpiece materials. The inscribed circle measures 3/8 inches, the corner radius is 1/32 inches, and the insert length is 9.70 mm (0.382 inches). The IC20 uncoated grade delivers a sharp, consistent cutting edge for applications where a bright finish and low cutting forces matter. The AS chip breaker geometry supports chip control across universal material groups.

This insert is used in CNC turning and manual lathe operations across general-purpose machining environments. Its CCGT designation and positive rake geometry make it a common choice for finishing passes on non-ferrous metals, stainless steels, carbon steels, and high-temperature alloys. Workpiece material codes H, K, M, N, P, and S are listed as primary applications, confirming its universal material compatibility. It is installed by machinists and CNC operators in production shops, job shops, and maintenance machining settings.

Key Features

• 80-degree diamond insert shape (code C) with positive rake for reduced cutting forces
• IC20 uncoated solid carbide grade with sharp, bright edge for finishing applications
• AS chip breaker geometry for effective chip control across universal material groups
• Screw-on insert holding method for secure, repeatable seating in compatible toolholders
• 7-degree relief angle (clearance code C) and tight tolerance code G for dimensional consistency
• Maximum depth of cut of 3.00 mm (0.118 inches)

Compatibility

Designed for use in CCGT-style screw-on turning toolholders accepting a 3/8-inch inscribed circle, 80-degree diamond insert. Compatible with universal workpiece material groups coded H, K, M, N, P, and S per ISO standards. Conforms to ISO 13399.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the machine before changing inserts. Use the appropriate torx or hex key to seat the screw-on insert to the toolholder manufacturer's specified procedure — do not overtighten. Inspect the insert pocket and seating surface for chips or debris before placing the insert to ensure proper contact and dimensional accuracy.
