Iscar 5540010 Turning Insert Ccgt IC20 Solid Carbide

Product Description

The ISCAR 5540010 is a solid carbide turning insert designed for precision external and internal turning operations on CNC lathes and turning centers. Manufactured to the CCGT insert style with an 80-degree diamond shape, this uncoated IC20-grade insert delivers sharp cutting geometry suited to finishing passes and light interrupted cuts. It features a positive rake angle, a 0.0079-inch corner radius for tight-tolerance work, and an inscribed circle of 0.2500 inches. The AS chip breaker geometry controls chip evacuation effectively across a range of workpiece materials. Licensed machinists and CNC operators install this insert as part of the Isoturn series tooling system.

This insert is suited for turning applications on non-ferrous metals, cast iron, stainless steel, and steel workpieces, corresponding to ISO material groups K, M, and N as primary designations, with additional suitability across H, P, and S classifications. Typical applications include finish turning on tight-tolerance components in production and job-shop environments where surface finish and dimensional accuracy are critical. The maximum depth of cut is 2.00 mm (0.0787 inches), making this insert appropriate for light to moderate stock removal rather than heavy roughing passes.

Key Features

• CCGT insert style with 80-degree diamond shape for versatile turning geometry
• IC20 uncoated solid carbide grade for sharp-edge performance on non-ferrous and finishing applications
• Positive rake angle reduces cutting forces and heat generation at the tool-workpiece interface
• AS chip breaker promotes controlled chip formation during light and finish turning
• 0.0079-inch corner radius supports fine surface finishes on precision parts
• Screw-holding method provides secure, repeatable seating in compatible toolholders

Compatibility

Designed for use in ISCAR Isoturn series toolholders that accept CCGT-style inserts with a 1/4-inch inscribed circle and screw clamp holding method, conforming to ISO 13399 standards.

Installation Notes

CNC machinists and turning specialists install this insert by securing it with the specified clamping screw to the manufacturer-recommended torque using a calibrated torque driver — consult the toolholder documentation for the correct fastener spec. Power down and lock out the spindle before indexing or replacing inserts. Inspect the pocket seat and clamping components for chips or wear before seating a new insert to ensure proper contact and runout. Handle solid carbide inserts with care to avoid edge chipping prior to use.
