Iscar 5566758 Turning Insert Dcmt 3-0-PF IC806 Solid Carbide

Product Description

The ISCAR 5566758 is a solid carbide turning insert in the DCMT style, designed for precision external and internal turning operations on CNC and manual lathes. It carries the IC806 manufacturer grade with a TiAlN coating applied via PVD process, including ISCAR SumoTec proprietary coating technology. The insert features a 55-degree diamond shape with a positive rake angle and a 7-degree relief angle (clearance code C). The PF chip breaker geometry promotes controlled chip evacuation in demanding cuts. With a 0.375-inch inscribed circle and a 0.008-inch corner radius, this insert delivers tight tolerances (tolerance code M) in finishing and semi-finishing passes.

This insert is engineered primarily for machining superalloys and titanium, making it well-suited for aerospace, medical, and energy sector components where hard, heat-resistant materials are the norm. It is used in single-end screw-held toolholders compatible with DCMT-style pockets. The Isoturn series designation places it within ISCARs broader turning system, intended for shops running high-temperature alloys where tool life and edge stability are critical. Licensed machinists and CNC tooling specialists typically source this insert for applications demanding consistent performance on difficult-to-machine materials.

Key Features

• IC806 grade with TiAlN PVD coating and SumoTec proprietary coating technology for enhanced wear resistance in superalloy and titanium cutting
• 55-degree diamond insert shape (shape code D) with positive rake for reduced cutting forces
• PF chip breaker geometry designed for controlled chip formation in finishing and semi-finishing
• 7-degree relief angle (clearance code C) with tolerance code M for precise, repeatable fit in compatible toolholders
• Screw-held, single-end mounting for secure clamping in DCMT-style pockets
• Submicron carbide grade material for improved toughness and edge integrity at elevated cutting temperatures

Compatibility

Designed as an OEM-style replacement turning insert for screw-held DCMT-style toolholders. Specific holder compatibility should be verified against ISCAR Isoturn toolholder specifications using the DCMT 3-0-PF ISO 13399 insert designation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or hex key to torque the clamp screw to the toolholder manufacturers specification — do not overtighten, as this can fracture the carbide insert. Inspect the toolholder pocket for debris or wear before seating the new insert to ensure full contact and proper edge presentation.
