Iscar 5500027 Ccmt 3-2-14 IC20 Carbide Turning Insert

Product Description

The ISCAR 5500027 is a solid carbide, uncoated turning insert in the CCMT style, designed for precision external and internal turning operations on CNC and manual lathes. It belongs to the Isoturn series and features an 80-degree diamond insert shape, a 3/8-inch inscribed circle, and a 1/32-inch (0.0315 inch) corner radius. With a positive rake geometry and a 7-degree relief angle, this insert is engineered for clean, controlled cuts in a range of metalworking applications. It is held in place by a screw-type clamping mechanism and carries ISO 13399 standardization, making it straightforward to specify and source across tooling systems.

The ISCAR 5500027 is suited for turning applications involving cast iron, non-ferrous metals, stainless steel, and high-temperature alloys, corresponding to ISO workpiece material classifications K, M, N, H, and S. The uncoated IC20 grade solid carbide substrate performs best in finish and semi-finish turning passes where edge sharpness and dimensional accuracy are priorities. This insert is typically used in production machining environments by CNC machinists and tool-and-die professionals on toolholders configured for CCMT-style inserts with screw-on retention.

Key Features

• CCMT insert style with 80-degree diamond shape and positive rake for reduced cutting forces
• Solid carbide IC20 grade, uncoated — optimized for sharp-edge finish turning
• 3/8-inch inscribed circle (0.3752 inch) with 1/32-inch corner radius (0.0315 inch)
• Maximum depth of cut of 0.1181 inch (3.00 mm) for controlled material removal
• Screw-holding method for secure, repeatable insert indexing
• Conforms to ISO 13399 standards; Isoturn series with chip breaker designation 14

Compatibility

Designed for use with CCMT-style screw-on turning toolholders. Compatible with toolholder bores accommodating a 0.1732-inch (4.40 mm) hole diameter. Suitable for ISO material groups H, K, M, N, and S. Material grade equivalents C2 and C3 apply.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key driver to seat the clamping screw to the toolholder manufacturer specification — do not overtighten. Verify insert seating and shim condition before resuming cutting operations.
